About the AirTAC GL400
The AirTAC GL400 is a G-series air line lubricator. It has 3/8", 1/2" ports (PT thread as standard, G also stocked). Operating pressure is 0.05 – 1.0 MPa (7 – 145 psi).
The drip unit is diaphragm-sealed, so the oil feed stays stable; one turn of the adjusting ring covers the whole range and the feed changes almost linearly with it. The drip design keeps the pressure loss low, and oil can be topped up without shutting off the air. Proof pressure 1.5 MPa (215 psi), temperature -5 to +70 °C (no freezing).
