GL200, GL300 and GL400 air lubricators provide adjustable oil delivery for pneumatic circuits requiring oil mist. The oil-feed ring turns through one revolution, with graduations for setting the feed quantity. Bowl capacities of 25mL, 75mL and 160mL correspond to the three body sizes.

The oil-drip mechanism uses a gap seal and a nozzle that creates negative pressure at the oil outlet. The feed-ring graduation provides an approximate indication of oil delivery, with an approximately linear relationship between ring position and feed quantity.
In GL300-10, G identifies the series, L identifies the lubricator function, 300 identifies the body size and 10 identifies the PT3/8″ port. Available body sizes are 200, 300 and 400.
| Port code | Connection |
