Feihe water-lubricated oil-free screw — WY / PM / WYH selections — Shanghai Feihe Compressor Manufacturing

Datasheet

Product overview

Power: Selected PM8F / PM22F: 7.5 / 22 kW · Pressure: PM examples 0.8 MPa; WYH separately · Flow: PM22F 1.1–3.7 m³/min at 0.8 MPa

Feihe's water-lubricated oil-free page separates standard WY, PM variable-speed, high-pressure WYH and low-pressure WYL parameter tables. Selected PM points are FHOGDWY-PM8F: 7.5 kW with 0.4–1.2 m³/min at 0.8 MPa, and FHOGDWY-PM22F: 22 kW with 1.1–3.7 m³/min at 0.8 MPa. PM22F separately lists 0.9–3.2 at 1.0 MPa and 0.8–2.8 m³/min at 1.25 MPa. These ranges are pressure-specific selections; their complete volumetric reference conditions and operating control range need the actual duty sheet.

The PM22F row distinguishes cooling-water quantity of 5 T/H from lubrication-water quantity of 30 L/min, with stated cooling-water inlet temperature below 32°C. Its dimensions are 1400 × 1000 × 1520 mm, listed mass 780 kg and 1-inch outlet. The selected motor supply is 380 V / 50 Hz, IP54. Agree water quality, circuit pressure and return conditions, make-up/drain behavior, water treatment and protection; neither water column establishes the site's purchased-water consumption.

The separate FHOGDWYH-22F row gives 22 kW, with 2.0 / 1.9 / 1.8 m³/min at 1.6 / 2.0 / 2.5 MPa. Do not combine it with the PM22F flow or the WYL low-pressure range. The standard WY table's third pressure heading reads 12.5 under MPa, unlike the PM table's 1.25; that ambiguous heading is excluded rather than silently corrected. The original public product image is labelled FHOGDWY-132 and illustrates the wider family, not these selected model ratings.

Water lubrication identifies the compression method. Define the process purity target, downstream dryer/filters, sampling point and acceptance test; obtain model-scoped oil-free evidence rather than treating the site's ISO9001 wording as an air-purity class. Confirm package input, cooling/ambient limits, water-service access, wear parts, manuals and commissioning requirements.
