The AirTAC Airtac GL Air Lubricators GL30010JG is a genuine G-series air lubricator. It meters an oil mist into the compressed-air line so cylinders, valves and air tools downstream stay lubricated, with PT3/8" ports and a pc oil bowl. A lubricator does not filter or regulate — it goes last in the line, after the filter and the regulator.
The AirTAC GL30010JG is a G-series air lubricator: it adds a fine oil mist to a compressed air line to keep downstream pneumatic tools, cylinders and valves running smoothly. It performs lubrication only - there is no water filtration and no pressure regulation in this unit - and this code decodes to the 300 size with a 3/8 in G (BSPP) female port. The J suffix means it comes without a mounting bracket. This is a genuine AirTAC part in the GL series, which spans sizes 200, 300, 400 and 600 with a choice of PT, G (BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). For this 300 size the bowl is polycarbonate. Rated flow figures are published as curves rather than a single number, so ask us and we will confirm the datasheet for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. A lubricator has no drain, no regulating mechanism, no gauge and no filter element, so none of those figures apply. Oil grade, bowl capacity, flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GL300 | G-series air lubricator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| J | Supplied without bracket. A bracket ships by default; J orders it without. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
The lubricator has the shortest code of the six G-series subfamilies — size, port, bracket, thread. There is no drain, pressure-type, gauge or filtering-grade position. Example: GL300-10JG is a 300 body, PT3/8", no bracket, G (BSPP) thread.
A larger body carries a larger port and passes more air. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GL600 uses an aluminium-alloy oil bowl; the 200, 300 and 400 bodies use PC.

| Line order | Filter first, then regulator, lubricator last |
Mists oil into the compressed air feeding air chucks, clamps and air-powered accessories on a machining centre, reducing wear on moving seals during every cycle.
Lubricates the air supply to pick-and-place cylinders and diverters on a carton or bottle packaging conveyor, keeping high-cycle actuators sealing and moving freely.
Feeds lubricated air to impact drivers, ratchets and riveters at assembly stations, protecting internal vane motors through a full shift of intermittent use.
Choose the size by the port and flow demand of your line: GL200 takes smaller ports, GL300 (this model, 3/8 in) and GL400/600 step up for larger ports and higher air demand. This GL30010JG has a G (BSPP) thread; PT is the standard thread on the series and NPT is also a catalogue option if you prefer. The J suffix means no mounting bracket is fitted - if you want the bracket version, order the code without the J. Pair this lubricator with a separate AirTAC GF filter and GR regulator if your line also needs water removal and pressure control, or use a GC combination instead. Because published flow data comes as curves rather than one rated figure, send us your air consumption and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The oil mist travels downstream, so if any branch of the line must stay oil-free, take that branch off before the lubricator. We will confirm the recommended oil grade from the factory datasheet on request.
AirTAC publishes lubricator flow as characteristic curves rather than a single rated-flow figure, so we do not quote a number that could mislead your sizing. Tell us your line pressure and air consumption and we will confirm the relevant datasheet figures for the GL300 at 3/8 in on request.
The J suffix means this unit is supplied without a mounting bracket - drop the J if you want the bracketed version - and the trailing G is the thread option, a 3/8 in G (BSPP) female port. PT is the standard thread for the series and NPT is available as a catalogue option, so pick the code that matches your pipework.
