Fixed Speed Air Compressor

Not every factory needs variable speed. When air demand holds flat across the shift, a constant-speed machine does the same job with simpler controls and a lower purchase price - the logic behind this fixed speed air compressor, built around a standard industrial-frequency asynchronous motor. The motor technology is mature and proven, easy for local technicians to diagnose and service anywhere in the world, and star-delta starting limits inrush current so the unit starts gently on a normal workshop grid. Because the machine runs at constant RPM, delivered pressure stays steady with small fluctuation, which suits tools and production machines that expect a stable supply rather than modulation. The control panel stays intentionally simple: pressure readout, load-unload status and basic alarms, so operators without compressed-air training can run it safely from day one. The design keeps components generic and globally available, so consumables and spare parts are inexpensive, and the platform is rated for 24-hour continuous duty. The range is deliberately compact: 0.8 to 3 cubic meters per minute at 8 to 13 bar with 7.5 to 18.5 kW, which targets small shops and single-line users rather than large central stations. The buyer logic is that on a flat load profile, a fixed-speed machine avoids paying for variable-frequency hardware that will never recover its cost, and its simpler control and fewer electronic parts mean fewer things that can break in a small workshop. The electrical and control components are standard industrial parts available from local suppliers in most markets, so a failed sensor or contactor can be replaced without waiting for an imported spare, and the absence of inverter electronics makes the machine tolerant of dusty, humid workshop floors.

Comps backs every unit with a one-year warranty and continues with lifetime maintenance service afterward at favorable parts prices. For a fixed-speed buyer, whose purchase decision is driven by low cost of ownership, this long-term service commitment matters: generic components stay affordable and the machine keeps running years after delivery.

Applications

 

Small processing workshops. The compact 7.5-18.5 kW range and simple controls match small shops that run a stable air load and want easy, local maintenance.

Auto repair shops and hardware processing. Steady 8-13 bar supply feeds pneumatic tools and spray guns without the complexity of inverter control, which lowers both purchase price and service needs.

Packaging, printing and woodworking machinery. Fixed load profiles let the constant-speed machine run at its efficient operating point all day, avoiding the part-load penalty that variable drive is usually bought to solve.

Customization

 

We set the voltage and frequency to your local grid, select the pressure tier between 8 and 13 bar, and adjust the outlet connection, canopy color and skid layout. OEM branding is available, and customized configurations can be developed from your drawings.

All units are packed for export on wooden pallets with plastic foam cushioning to protect the canopy, cooler and control panel during sea freight. We support EXW, FOB, CIF and DDP terms. Payment is 30% advance before production and 70% balance before shipment. Standard units are delivered in 40 days, while customized units take about 60 days.
