FAQ

IMI Norgren recommends using high-quality, non-detergent mineral oils with a viscosity between ISO VG10 and VG32 for optimal performance. Avoid synthetic oils or oils with additives unless explicitly approved, as they can damage the seals and internal components.

The oil drip rate is adjusted using the yellow knob located on the top of the unit. Turning it counter-clockwise increases the flow, and turning it clockwise decreases it. The correct rate depends on the application, but a general starting point is one to two drops per minute for every 10 SCFM (Standard Cubic Feet per Minute) of air flow.
