AirTAC GL400-15 Lubricator (GL40015JG)
The AirTAC AirTAC GL400-15 Lubricator (GL40015JG) 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 PT1/2" 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.

About the AirTAC GL400-15 Lubricator (GL40015JG)
GL40015JG is a single-function air lubricator from the AirTAC G series: it adds a controlled oil mist to a compressed-air line so downstream cylinders, valves and air tools receive continuous lubrication. It performs no filtration and no pressure regulation - those jobs belong to separate GF and GR units upstream. This size 400 configuration carries G1/2 ports (1/2 in G / BSPP thread), has no mounting bracket (the J code), a polycarbonate bowl, a maximum working pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C.
You are buying a genuine AirTAC part. The GL family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, in PT, G (BSPP) and NPT threads, with or without a mounting bracket. Because AirTAC publishes flow for this series as curves rather than a single rated figure, we confirm the exact flow and the full datasheet for your model on request.

| Oil bowl material | PC |
| Bracket | Supplied without bracket |
| Fluid | Compressed air |
|---|---|
| Inlet pressure | 0.05 - 1.0 MPa (7 - 145 psi) |
| Max. working pressure | 1.0 MPa (145 psi) |
| Temperature range | -5 to +70 °C (unfreeze) |

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.
Model Code: AirTAC GL400-15 Lubricator (GL40015JG)
| GL400 | G-series air lubricator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 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.
Size Class
- GL200PT1/8" - PT1/4"
- GL300PT1/4" - PT1/2"
- GL400PT3/8" - PT1/2"
- GL600PT3/4" - PT1"
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.

Where the AirTAC GL400-15 Lubricator (GL40015JG) Is Used
European machine retrofits
Imported machines built to BSPP standards need G-thread ports throughout the air preparation stack. GL40015JG drops straight into those 1/2 in lines and keeps the machine's cylinders and air tools fed with lubricated air.
Woodworking shop air drops
Nailers, sanders and pneumatic clamps at a woodworking bench run for hours at a stretch. A lubricator on the 1/2 in drop feeds oil mist to the tools so seals and valves last through long production runs.
Automated pick-and-place cells
Grippers and slides cycling thousands of times per shift depend on lubricated air. Mounted directly in the manifold line, this lubricator keeps every cycle supplied with a fine oil mist.
Is the AirTAC GL400-15 Lubricator (GL40015JG) the Right Lubricator?
Size 400 serves the upper-middle of the GL range: drop to 300 or 200 for smaller drops, or step to 600 where a 1 in port is required. This code specifies the G (BSPP) thread - the right match for European-standard fittings - while PT is the standard thread and NPT is a catalogue alternative. The J code means no mounting bracket is supplied, so plan for direct pipe or panel fixing; a bracket can be added when ordering. AirTAC publishes flow for the GL series as curves, not a single rating, so ask us to confirm sizing against your line pressure and air consumption before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" here)
- ✓ Downstream equipment actually needs oil
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Bracket needed, or order with J
- ✓ Bowl material: PC, or aluminium on GL600
- ✓ Fit after the filter and regulator
Installation & Maintenance Notes
- check Fit last in the line: filter, then regulator, then lubricator.
- check Mount vertically, bowl down, following the airflow arrow.
- check Keep inlet pressure within 0.05 - 1.0 MPa.
- check Use only oil approved for pneumatic lubricators.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Check the oil level regularly; top up before it runs dry.
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 GL400-15 Lubricator (GL40015JG) FAQ
AirTAC publishes flow for the GL series as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and expected air consumption and we will confirm the flow and the full datasheet for this model on request.
The trailing G in the code specifies G (BSPP) thread, which matches European-standard fittings. PT is the AirTAC standard thread, and NPT versions are also catalogue options - choose the one that matches the pipework and fittings already on your machine.
