Low-pressure air end running at 3-5 bar — volume without wasted compression. The 22-185 kW Low Pressure Screw Air Compressor is built for continuous industrial duty. It runs on a direct-coupled air end with no belts to re-tension, and it is delivered as a complete package — airend, motor, cooler, separator and controller on one base frame — so on-site work is limited to power, piping and a drain.
A single cutaway view of the whole unit: airend, drive motor, separator tank, coolers, filtration and controller mounted on one base frame. Use it to check the space envelope and service access before ordering.
Vector inverter that trims motor speed to match actual air demand instead of loading and unloading at a fixed speed. Highest saving on installations that sit part-loaded most of the day.
A TEFC induction motor sized to the airend with a wide service factor. Direct-coupled to the airend through a flexible coupling — no belt tension to re-check, no belt dust in the enclosure.
A single-stage oil-injected rotary screw airend with asymmetric rotors machined and lapped as a matched pair. Large-diameter rotors run at low speed for a long bearing life and a stable specific power figure.
Spin-on full-flow oil filter with a large filtration area. It protects the airend bearings from wear particles and keeps the oil service interval predictable.
Wet separator tank with a two-stage element that brings carry-over down to a few parts per million. The vertical design gives the oil time to settle before the next cycle.
Aluminium plate-fin coolers for the oil and the compressed air, with a fan sized for ambient conditions. Keeps discharge temperature inside the limits that protect the oil charge.
Optional telematics module that logs pressure, temperature, running hours and service due dates to a web dashboard or phone app. Useful when the machine runs unattended.
Specifications for this model are available on request.
High-volume, low-pressure air is the core requirement.
Process air where volume matters more than pressure.
Furnace and forming line air.
Dilute-phase transport of powders and granules.
Cement, fly ash and similar materials.
Every unit ships with an 18-month warranty on the air end and 12 months on the rest of the machine, counted from commissioning or 24 months from shipment, whichever comes first.
Each machine is run on the test bench and the delivered flow, working pressure, current draw and noise level are recorded against the datasheet before it is crated.
Installation drawings, piping diagrams and a commissioning checklist are supplied with the machine, with remote engineering support during start-up.
Airends, motors, controllers, filters, separators and cooler assemblies are held in our own warehouse, so service parts are not tied to a production run.
Processes that need volume rather than pressure: textile and air-jet weaving, chemical fibre spinning, glass making, and dilute-phase conveying of cement or fly ash.
Because you would be paying to compress air to a pressure you then throw away at a regulator. A low-pressure airend delivers the same volume with a lower compression ratio, so the specific power is lower.
Yes. The inverter option is listed in the specification table and suits the varying demand typical of these processes.
The lower compression ratio means a lower discharge temperature, which is easier on the oil and the separator element.
