22-132 kW 2-Stage Compression Screw Air Compressor

22-132 kW 2-Stage Compression Screw Air Compressor

Model: WBS22II
Capacity FAD: 155 cfm
Working pressure: 7 bar
Motor Power: 22 kW
Description

Two-stage compression with intercooling — lower specific power than a single stage at the same pressure. The 22-132 kW 2-Stage Compression 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.

Unit Overview

Unit Overview

The machine as shipped: canopy, control panel, service doors and mounting feet.

Airend — the Compression Element

Airend — the Compression Element

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.

High-Efficiency Drive Motor

High-Efficiency Drive Motor

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.

Variable Speed Inverter

Variable Speed Inverter

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.

Controller Display

Controller Display

Colour touch display showing line pressure, outlet temperature, running hours and the next service date, with alarm history for fault finding.

Oil-Air Separator Tank

Oil-Air Separator Tank

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.

Why This Range

Comparison of the two-stage design against a conventional single stage at the same discharge pressure: lower compression ratio per stage, lower discharge temperature, and lower specific power.

  • 18-Month Warranty

    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.

  • Factory Test Before Shipment

    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.

  • Engineer Commissioning Support

    Installation drawings, piping diagrams and a commissioning checklist are supplied with the machine, with remote engineering support during start-up.

  • Spare Parts Held in Stock

    Airends, motors, controllers, filters, separators and cooler assemblies are held in our own warehouse, so service parts are not tied to a production run.

FAQ
What is the advantage of two stages?

The air is compressed in two steps with intercooling between them. That lowers the compression ratio per stage and the discharge temperature, which raises efficiency and extends the life of the airend and the oil.

Is it worth the extra cost over a single stage?

It pays back on machines that run loaded for long periods, and on installations where the pressure is at the top of the range. On intermittent light duty the difference is smaller.

Is variable speed available?

Yes. The inverter option appears in the specification table and combines well with the two-stage airend on part-load duties.

What is the service interval?

Same consumables as a single-stage screw machine — intake filter, oil filter, separator element and oil — on the hours given in the manual.
