SJ-40A / Fixed-speed screw compressors
SJ-40A is a 30 kW Fixed-speed screw compressors. Single-stage fixed-speed screw compressors with asynchronous motors for workshop and factory air supply. Compare motor power and air delivery at the pressure required by your equipment. Overseas configurations use IP55 motor protection.
The listed working-pressure configuration is 8 / 10 / 12.5 bar · 116 / 145 / 181.3 psi. Maximum listed air delivery is 5 m³/min / 176.6 CFM; use the performance row for your chosen pressure when comparing equipment. Final selection should include the production demand, operating hours and available electrical supply. Receiver storage, drying and filtration can be specified around the installation as separate system components.
Consider SJ equipment for general industrial pneumatic duties and established air systems with a clear demand profile. Where demand changes substantially during the day, compare a permanent magnet VSD configuration as part of the same project review.
Thick enclosure panels made from materials conforming to Chinese national standards help reduce resonance and provide stable cabinet support. Internal thermal and acoustic insulation lining helps reduce operating noise.

COMPLETE YOUR AIR SYSTEM
A matching refrigerated dryer.
One model to start with.
AB standard: 10 bar / 145 psi.
Flow-based starting point using the maximum listed compressor air delivery. Standard AB dryers are rated at 10 bar; compressor configurations above 10 bar require suitable high-pressure air treatment. Final sizing also accounts for inlet and ambient temperatures and required air quality.
INSTALLATION & MAINTENANCE
Prepare for dependable operation.
Before installation
Review the confirmed electrical specification, connections, dimensions and service clearances. Plan suitable ventilation and condensate drainage, and follow the supplied operating instructions for installation and commissioning.
Routine care
Use the equipment maintenance schedule and the specified consumables. Keep a record of running hours, service work and operating conditions. The site environment and duty pattern affect maintenance planning.
When you need support
Send the model and serial number, nameplate photo, operating conditions and a clear description of the issue. Include any controller alarm and relevant photos or video. This information helps identify the appropriate technical guidance or replacement component.
WARRANTY & SUPPORT
Confirm the details
before you order.
MATEOU offers a two-year equipment warranty. Applicable coverage and terms are confirmed in your quotation and order documents. Request operating information, maintenance guidance and the appropriate consumables for your selected configuration.
Request current exterior, internal, detail and main-component photos of the selected equipment configuration.
