GRF W-Series Medium & High-Pressure Piston Compressors
0.5–2.0 m³/min at 20–100 bar: multi-stage piston sets with intercooling for laser-cutting assist air, high-pressure leak testing and blow-moulding boosting.

GRF W-Series Medium & High-Pressure Piston Compressors
0.5–2.0 m³/min at 20–100 bar: multi-stage piston sets with intercooling for laser-cutting assist air, high-pressure leak testing and blow-moulding boosting.
Overview
The W family matches cylinder combinations and stage count to discharge pressure: two to three stages for 20–30 bar, three for 70 bar and four for 100 bar, with intercooling holding stage temperatures down. Open-frame, belt-driven sets with fan cooling keep service points visible; high-pressure cylinders and valve groups are selected by pressure class — a practical source for low-flow, high-ratio process air.
Key features
Eight ratings from 20 to 100 bar — pick the duty pressure directly.
Intercooling lowers discharge temperature and power at high ratios.
Belt drive and fan cooling; straightforward service and common spares.
Laser assist air, leak testing, boosting and high-pressure trials.
