Product overview
Gairs OGWBY / OGWY ordinary-pressure water-lubricated VSD compressors from Gairs / Shanghai Gairs Machinery
Gairs presents OGWBY as a water-lubricated, oil-free single-screw variable-speed family. The original parameter table uses OGWY model codes, so retain the complete offered designation rather than assuming the family heading identifies every motor or cooling version.
For OGWY22F/S, the table lists 22 kW motor power and delivery ranges of 1.5–3.7 m³/min at 0.7 MPa, 1.4–3.4 at 0.85 MPa and 1.2–3.0 at 1.0 MPa. Its listed lubricating-water volume is 30 L. That volume is not a cooling-water flow rate or a guaranteed daily make-up requirement. F identifies air cooling and S water cooling; the table footnote distinguishes OGWB variable-frequency and OGWY permanent-magnet variable-frequency starting. Confirm the exact code and current configuration in the offer.
For a varying industrial demand, request minimum stable delivery, load control, package input and the flow measurement/reference conditions at the selected pressure. State the electricity and site cooling conditions. Specify the water-treatment, make-up and maintenance scope separately from downstream drying and filtration. A manufacturer's oil-free family description does not define particle, moisture or microbial quality at the user equipment; agree the required air-quality limits and acceptance test for the actual system.

Specifying a Oil-free duty
| Duty | Write on the RFQ |
|---|---|
| Compressor for a pharmaceutical plant | Pharma procurement is a document pack: IQ/OQ support, material certs, residual oil. The machine is the easy part if the RFQ lists the papers. |
| Class 0 oil-free compressor | Class 0 means a stated test method at a stated point in the air system. An oil-free airend without a paper is not Class 0 on this desk. |
| Oil-free screw compressor manufacturers in China | Oil-free screw is a different factory from oil-injected screw. Dry airends and water-lubricated airends are also different quotes. Name the architecture. |
