Our Products

All our products use the rocking piston technology, although we offer diaphragm versions for certain specialist applications. Available flow rates vary from under 10lpm (0.36cfm) to over 400lpm (14.1cfm), with pressures ranging from 29″Hg (vacuum) to over 11 bars (pressure). If you include the different voltage ranges, we offer over 1,000 models.

GSE has a global reputation for manufacturing OEM vacuum pumps and compressors with a very long life and very low noise levels.
