WBS / WBV stationary screw air compressors — Windbell / Zhengzhou Windbell Machinery

Datasheet

Product overview

Power: 7.5 kW · WBS7.5 motor · Pressure: 7 / 8 / 10 / 12 bar · matched duties · Flow: 1.20 / 1.10 / 1.00 / 0.80 m³/min FAD

Windbell's current WBS7.5 table publishes four paired FAD selections for a 7.5 kW motor: 1.20 m³/min at 7 bar, 1.10 at 8 bar, 1.00 at 10 bar and 0.80 at 12 bar. Compare the pressure needed at the compressor after piping and treatment losses, then request the applicable flow test/reference conditions. Motor power alone does not establish delivery or measured package consumption.

The standalone WBS7.5 is listed at 890 × 560 × 840 mm, 200 kg, with a G¾ outlet and 380 V / 50 Hz supply or customization by enquiry. The same page also shows a separate all-in-one receiver, dryer and filter arrangement. Its components and footprint must be specified independently; the standalone dimensions do not cover that package.

The manufacturer describes a direct-coupled oil-injected screw machine, IP55 motor, intake/oil filtration and an oil-air separator. Oil and compressed-air coolers are separate, with a centrifugal blower for cooling. Plan the cooling-air path and maintenance clearance from the selected drawing. Specify moisture, oil and particle requirements downstream and agree treatment and condensate scope.

WBS denotes fixed-speed equipment and WBV variable-speed equipment; the manufacturer offers 7.5 kW versions in both routes. Select from the measured demand pattern and operating hours, then confirm the actual starter or inverter and electrical supply. The table lists alternative starting/control arrangements, not a promise that all are included simultaneously. The original WBS-7.5 image shows equipment internals; obtain the ordered machine's installation drawing, control description, performance record and routine spares before final acceptance.
