Direct Drive Screw Compressors: 22–315 kW in Sri Lanka
Compare MAC3 MSD direct drive screw compressors in the 22–315 kW family for your Sri Lankan factory. Send the delivered-air requirement at working pressure, operating hours and installation details. Ask Vortex Axion for an identified model proposal, low-noise options and a free site inspection.
Performances
Assess a direct drive model using documented output at the required pressure. MAC3’s family reference lists operation up to 43°C ambient; confirm the offered version’s limits and the plant-room conditions. Compare the complete duty and maintenance scope rather than treating the family description as a universal cost or performance guarantee.
Ergonomic
For Direct Drive – 22 To 315 kW, review the fitted controller, alarm functions and operating instructions. Confirm which start/stop, monitoring and maintenance-notification features are included in the quoted version.
Our Commitment to You
Request Direct Drive – 22 To 315 kW details for your Sri Lanka application from Vortex Axion in Rajagiriya. Include the required flow and pressure, operating hours and site location. Call 0777 123 263 or 0117 101 818 to confirm the configuration, availability and quotation.
EQUIPMENT
Electric motor WEG
MAC3 lists a WEG motor with IP55 protection and Class F insulation for this family. Ask the quotation to identify the actual motor and electrical version supplied.
TAMROTOR series ENDURO air-end
The family reference identifies a TAMROTOR ENDURO air-end. Request the selected model’s rating, operating instructions and component identity; a brand name alone does not establish site-specific output or operating cost.
Electronic controller SMARTRONIC LITE - SMARTRONIC
MAC3 lists SMARTRONIC LITE or SMARTRONIC controller references, with functions depending on the version. Confirm alarms, maintenance reminders, scheduling and communications on the actual offered model, including any additional configuration work.
SCHNEIDER ELECTRIC starter and protections
The manufacturer identifies Schneider Electric starter and protection components. Have the actual supplied arrangement and site connection requirements reviewed using current model documents.
Direct drive
Confirm the offered direct drive arrangement, coupling and guards from the model documents. Request the relevant service instructions and leave access for inspection and maintenance in the plant-room plan.
EBM-PAPST air cooling fan
The family reference lists an EBM-PAPST cooling fan. Review the selected version’s ventilation and cooling-air requirements with the proposed room arrangement.
Model data: Request a current technical schedule for the selected direct drive compressor. See the MAC3 manufacturer reference for the published family table. Confirm flow, pressure, electrical version, dimensions and included equipment in the quotation.
FIELDS OF APPLICATION
Direct drive compressor price in Sri Lanka
A direct drive compressor quotation should identify the exact MAC3 MSD model, delivered airflow at your working pressure and the equipment included. Send the factory location, production schedule and known air demand to Vortex Axion. A motor power label alone is not enough to compare two offers.
Request separate prices for the compressor, dryer, filters, receiver and installation work. Ask whether transport, electrical connection, piping and commissioning are included. Confirm lead time, taxes, payment conditions and warranty scope in writing before purchase.
MAC3 MSD direct drive manufacturer reference
MAC3 lists the MSD direct drive family from 22 to 315 kW. Its industry range is a starting point for discussion; request the current offered model documents. The photographs show manufacturer equipment references, not proof of local stock.
Review the MAC3 manufacturer page for published family information. Have the quotation identify any changes in motor, air-end, controller or electrical version. Keep the accepted technical schedule with the purchase order so the receiving team can check the actual supplied machine.
Start with your factory's air requirement
List the machines and pneumatic equipment connected to the network. For each, provide the required operating pressure, stated air consumption and normal running schedule. Mark which loads operate together and which are used only during short production peaks.
Where measurements are available, send them with the dates and operating conditions. If the requirement is estimated, say so. A direct drive selection should explain the demand basis rather than relying on an unexplained allowance or the power of the compressor currently installed.
Rated airflow at working pressure
Ask every proposal to state delivered airflow and the pressure used for that rating. Keep the unit visible: m³/min, litres per minute or CFM. Do not compare an intake-displacement number with delivered-air data without clarification from the supplier.
Use the same duty point for all quotations. If production needs several pressure levels, describe the arrangement and ask which duty governs selection. Retain a current data sheet for the selected direct drive model, including the definition and test conditions behind the reported flow.
Choose power after checking output
The electric compressor size guide helps organise enquiries by motor power. This page instead covers the MAC3 MSD equipment family. A capacity page and a family page answer different purchasing questions; the quoted model still needs to match the actual flow and pressure requirement.
When comparing a proposed replacement, provide the existing nameplate and explain why it is being changed. Ask whether the issue is insufficient delivered air, increased production, condition or control behaviour. A larger kW label should have a clear selection reason in the direct drive proposal.
Steady demand and operating schedule
Describe the number of production shifts, normal hours, shutdown periods and periods of reduced demand. Give examples of when equipment runs together. This helps the supplier assess whether the proposed operating arrangement fits the factory schedule.
If demand varies significantly, ask for a comparison with variable-speed equipment using the same requirement sheet. Direct drive describes the drive arrangement; it should not be treated as a complete description of system control or a guarantee that one machine suits every demand pattern.
Direct drive and variable-speed comparisons
Review the variable-speed family when assessing changing consumption. Ask both options to identify delivered flow, electrical configuration, control strategy and the scope of the proposed installation.
Compare the complete operating duty and quoted equipment, not only purchase price. Any estimated energy difference should state the baseline compressor, assumed working hours and demand pattern. Retain those assumptions so an eventual measurement can be compared against the actual proposal.
Electrical supply and starting requirements
Send available site voltage, phase information and any restrictions from the electrical contractor. Request the offered motor and starter data, together with the relevant connection documents. Ask who is responsible for cables, protection and installation work.
Have the responsible contractor review the selected machine documentation before work starts. The direct drive quotation should clearly separate supplied compressor components from site electrical work. A manufacturer’s family component list does not identify every electrical option included in a particular offer.
Room position and ventilation
Provide a room sketch showing entrances, existing equipment, ventilation openings and the proposed machine position. Include any limit on cooling-air discharge or duct routing. Request model dimensions and the manufacturer’s service clearances.
Ask the proposal to explain which site observations are still needed. Confirm that doors and panels can be opened for maintenance after the compressor, receiver and dryer have been placed. The direct drive cabinet image is useful for identification, but it is not a site-specific installation drawing.
Receiver, dryer and filter scope
Ask the offer to identify the air receiver and air treatment requirements alongside the compressor. State the downstream process’s air-quality needs and provide details of any existing treatment equipment.
Have the project drawing show each component and its connections clearly. Confirm the dryer rating basis, filter specification and drain arrangement with the supplier. A direct drive machine-only quotation should not be assumed to include storage, moisture control or every treatment item required by production.
Low-noise options and machine location
Tell Vortex Axion where people work relative to the proposed installation and whether there are restrictions on noise. Ask for the selected model’s declared sound data and its measurement basis before comparing alternatives.
Discuss low-noise options and location together, including access and ventilation. Avoid treating a catalogue sound figure as a promise about the whole room after installation. Any direct drive proposal involving acoustic changes should specify what is included and how the result will be assessed.
Controller and monitoring information
Ask the offer to identify the fitted controller and the functions available on the actual version. Describe any required scheduling, maintenance reminders, remote monitoring or connection to existing controls. Confirm accessories and configuration work separately.
Where several compressors share a network, provide a simple equipment list and explain current operation. Have the supplier describe the proposed coordination scope. The direct drive family reference should not be used as evidence that a complete multi-machine control scheme has already been designed for your factory.
Maintenance access and support
Request the supplied model’s operating instructions, service schedule and consumable identifiers. Discuss maintenance enquiries through the compressor services page. Give the existing machine identity and records when asking about replacement parts or support.
Before purchasing, confirm how visits and parts enquiries are arranged, what information is required and which costs are separate. Keep the model and serial details with the handover documents. Support availability for a direct drive compressor should be confirmed for the actual request rather than inferred from a range photograph.
Delivery, positioning and commissioning
Check the access route from unloading point to final position. Give doorway dimensions, floor changes and any handling restrictions to the supplier. Ask for the selected model’s mass and dimensions before agreeing transport and positioning responsibilities.
Record who will perform connections and what commissioning is included. Agree the conditions and observations to be recorded at handover. The direct drive machine, treatment equipment and system drawings should all match the accepted quotation before the installation is treated as complete.
Free site inspection for direct drive enquiries
Ask Vortex Axion about a free site inspection in Sri Lanka. Send the location, contact person, production hours and the reason for the enquiry. Prepare a room sketch, machine list and available flow or pressure readings.
Confirm appointment availability and the preliminary inspection scope. Detailed design, formal measurements and specialist testing may require separate proposals. A direct drive purchasing enquiry is easier to progress when known information, assumptions and outstanding questions are clearly listed before the visit.
Comparing quotation scope
Use one requirement sheet when requesting several offers. Check the exact model, pressure-duty data, motor, control version, receiver, treatment and installation responsibilities side by side. Ask the supplier to explain any excluded items before comparing totals.
Record later changes in a revised quotation. If the duty, location or production schedule changes, ask whether the original selection still applies. Keep the accepted direct drive proposal available to the maintenance and installation teams so they work from the current scope.
Preparing a direct drive enquiry for an existing factory
For an existing workshop or factory, begin with a short description of the problem you want the new equipment to solve. For example, say whether production has added machinery, operators report pressure interruptions, the installed unit is reaching the end of its serviceable life, or the site wants to compare operating costs. This gives the supplier a concrete reason to investigate instead of treating replacement as a like-for-like power-label exercise.
Attach one clear nameplate photograph for each retained compressor and label it with the equipment’s location. Add the available service history and a simple list of connected production machines. If operators have recorded faults or pressure readings, include the conditions under which those observations occurred. Information from a quiet period should not be presented as evidence of peak production performance.
Ask the direct drive proposal to distinguish three things: information supplied by the customer, assumptions used for selection, and items to be confirmed during the site review. If demand cannot yet be established, request clarification of what further observation is needed. Keep the updated requirement sheet with the quotation so changes in production or the intended location are visible to everyone reviewing the purchase.
Reading an equipment quotation before acceptance
Check the exact model designation throughout the quotation, technical schedule and supplied documents. A product-family heading is useful for discussion, but the order should identify the machine version being offered. Ask the supplier to clarify any discrepancy between a photograph, a catalogue example and the equipment schedule before treating them as the same configuration.
Make a simple inclusion list for the direct drive machine, storage, treatment, controls and accessories. Alongside it, record the installation tasks and the party responsible for each. Where an item is excluded, ask how it will be provided and who will coordinate its connection. This makes the final comparison easier to understand than a single price containing an unspecified mixture of equipment and labour.
Review warranty conditions, quotation validity, lead time and the required handover information together. If a site visit changes the recommended model or adds work, request a revised scope. Retain the accepted version and its date, rather than asking the installation team to interpret several earlier offers. Equipment changes should have a clear explanation and be recorded before delivery arrangements are finalised.
Keeping a direct drive handover record
Prepare a folder for the supplied machine identity, accepted duty, installation drawing and operating instructions. Add the actual serial number after delivery and record the controller and electrical version. The service team can then distinguish the installed equipment from a catalogue reference when support is requested later.
Ask the commissioning record to identify the operating conditions observed and any work still outstanding. Keep measured results separate from estimates made during quotation. If the factory was not operating under representative production conditions at handover, record that limitation and agree whether further observation is required. This avoids describing an assumed benefit as an established result.
Keep a change log when machines are added to the air network or working hours increase. Record the date, new requirement and related document revision. A future direct drive capacity or service enquiry can then refer to the current installation and explain what has changed since the equipment was selected. Clear records also help the site contact and maintenance team provide consistent information when arranging a visit.
Direct drive questions
Can I select by kW alone? Provide airflow, pressure and operating hours as well as the desired power range. Is a dryer included? Check the named equipment schedule. Are prices fixed on this page? Request a model-specific quotation with its validity and scope.
Does the image show local stock? It is a manufacturer reference. Can I request a low-noise option? Describe the site and request the actual model sound data. What should I send first? A machine list, duty requirement, location and existing nameplate are useful starting points.
