Airtac B52-GL Copper-Free Air Treatment Unit B52-GL300C10J
The AirTAC Airtac B52-GL Copper-Free Air Treatment Unit B52-GL300C10J 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 B52-GL Copper-Free Air Treatment Unit B52-GL300C10J
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. GL300C10J 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. The J suffix means no mounting bracket is fitted.
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 B52-GL Copper-Free Air Treatment Unit B52-GL300C10J
| 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 B52-GL Copper-Free Air Treatment Unit B52-GL300C10J Is Used
Workshop air tool drop lubrication
Installed in the drop from an overhead air line to a workbench, oiling grinders, drills and screwdrivers used across a shift.
Injection moulding machine actuator feed
Feeding oil mist to the pneumatic actuators that operate slides and ejectors on an injection moulding machine, mounted directly in the machine air circuit.
Trailer brake and door actuator supply
Lubricating the air cylinders that open and close curtains and tail lifts on commercial vehicle assembly and service lines.
Is the Airtac B52-GL Copper-Free Air Treatment Unit B52-GL300C10J 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 J suffix deletes the mounting bracket, so plan for direct line mounting or your own fixing method; the non-J version includes the bracket. 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 B52-GL Copper-Free Air Treatment Unit B52-GL300C10J FAQ
AirTAC publishes lubricator flow as curves, not as a single rated figure, so there is no one number to quote here. Send us your line pressure and air consumption and we will confirm the sizing and provide the datasheet on request.
It means the unit comes without the mounting bracket. Function, size 300 body, PT3/8 port, PC bowl and the -5 to 70 C working range are the same as the bracketed GL300C10; only the fixing hardware differs.
