AirTAC GL300-08 Lubricator (GL30008J)
The AirTAC AirTAC GL300-08 Lubricator (GL30008J) 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 PT1/4" 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 GL300-08 Lubricator (GL30008J)
The AirTAC GL30008J is a size 300 air lubricator supplying a fine oil mist to downstream cylinders, valves and air tools. It performs lubrication only - no filtration, no pressure regulation. The J suffix means no mounting bracket, which suits direct manifold or panel mounting where a bracket would be in the way. It carries a PT1/4 port in the standard PT thread, with a PC bowl rated to 1.0 MPa (145 psi) working pressure in a -5 to 70 C, non-freezing environment.
This is a genuine AirTAC part from the G series, available in sizes 200, 300, 400 and 600 with bracket and thread options to match your installation. Flow is published as curves rather than a single rating, so share your application conditions and we will confirm sizing and the full datasheet on request.

| 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 GL300-08 Lubricator (GL30008J)
| GL300 | G-series air lubricator, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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. |
| (blank) | PT 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 GL300-08 Lubricator (GL30008J) Is Used
Manifold-fed robot gripper circuit
On a pick-and-place cell, the gripper cylinders and mini valves on a common manifold need lubricated air. The bracketless GL30008J screws straight into the manifold inlet, keeping the lubrication point compact inside the cell frame.
Workshop impact wrench drop
At a maintenance bench, impact wrenches and air ratchets depend on misted oil for their vane motors. Installed at the quick-connect drop ahead of the tool, this lubricator oils the tool exactly while it is in use.
Lab automation air actuators
Benchtop laboratory equipment with small pneumatic actuators - clamps, lifters, shutter drives - benefits from a light, steady oil mist. The compact, bracket-free body mounts directly on the instrument's air inlet fitting.
Is the AirTAC GL300-08 Lubricator (GL30008J) the Right Lubricator?
This is the 1/4 inch (PT1/4) size 300 lubricator in the no-bracket configuration, intended for mounting where a bracket adds nothing - on a manifold plate, inside a control cabinet, or screwed directly into a machine's air inlet. If you would rather have the bracket, order the plain GL30008. Thread is PT as the standard; G (BSPP) and NPT can be ordered as catalogue options. If your air consumption outgrows a 1/4 inch port, step up to a size 400 or 600 body.
Because flow is published as curves and not a single rated figure, send us your line's air consumption and pressure and we will confirm the GL30008J suits the job before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GL300-08 Lubricator (GL30008J) FAQ
AirTAC publishes lubricator performance as flow curves rather than one rated flow number, so we do not state a single figure. Give us your working pressure and expected air consumption, and we will check the curve for the GL30008J and confirm sizing from the datasheet on request.
J means this unit is supplied without a mounting bracket - intended for manifold or direct mounting. If you want the bracket, order the plain GL30008 with the same PT1/4 port. Thread is PT as standard; G (BSPP) and NPT are available as catalogue options.
