Airtac GL Lubricator GL300C10
The AirTAC Airtac GL Lubricator GL300C10 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 See datasheet 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 GL Lubricator GL300C10
The AirTAC GL series is a dedicated air lubricator: it adds a fine oil mist to a compressed-air line and nothing else - there is no filtration and no pressure regulation in this unit. GL300C10 is the size 300 body with a PT3/8 port (PT is the standard thread; G and NPT are catalogue thread options). The PC (polycarbonate) bowl holds the oil, the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. This version is supplied with the mounting bracket.
This is a genuine AirTAC part distributed for the US market. The GL series is available in sizes 200, 300, 400 and 600, each in a range of port sizes, with or without the mounting bracket, and in PT, G (BSPP) or NPT thread. Lubricator flow is published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application.

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 GL Lubricator GL300C10
| GL300 | G-series air lubricator, 300 body — sets the port range. |
|---|---|
| C1 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Mounting bracket included. 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 GL Lubricator GL300C10 Is Used
Impact wrench and air ratchet supply
Feeding a fine oil mist to pneumatic impact wrenches and ratchets at a maintenance workshop bench, keeping tool motors and vanes oiled through the working day.
Packaging line cylinder lubrication
Mounted upstream of the valve island on a carton-forming or case-packing machine, so cylinders and directional valves on the line receive continuous oil mist.
Conveyor air vane motor supply
Lubricating the air vane motors that drive roller and belt conveyors in a distribution centre, supplied through a 3/8 inch branch of the plant air ring main.
Is the Airtac GL Lubricator GL300C10 the Right Lubricator?
Step up or down through the 200/300/400/600 sizes to match the port and flow path you need; size 300 here carries a 3/8 inch port. Thread: PT is the standard for this code - order the G (BSPP) or NPT variant if your pipework requires it. The mounting bracket is included on GL300C10; choose the J version if you do not want it. Because lubricator flow is published as curves and not as a single rating, ask us to confirm sizing against your air consumption before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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 GL Lubricator GL300C10 FAQ
AirTAC publishes lubricator flow as curves, not as a single rated figure, so there is no one number we can quote here. Tell us your line pressure and air consumption and we will confirm the correct size and the datasheet curve on request before you order.
Only the mounting bracket. GL300C10 is supplied with the bracket fitted; the J version omits it. The size 300 body, PT3/8 port, PC bowl, 1.0 MPa maximum inlet pressure and -5 to 70 C working range are identical.
