Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J
The AirTAC Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J 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.

About the Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J
The AirTAC GL30010J is a size 300 air lubricator that meters a fine oil mist into the compressed air serving your cylinders, valves and air tools. Lubrication is its only function - there is no filtration and no pressure regulation. The J suffix denotes the no-bracket version, intended for direct manifold or equipment mounting. It carries a 3/8 inch (PT3/8) port in the standard PT thread, with a PC bowl rated for 1.0 MPa (145 psi) working pressure at -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, offered in sizes 200 through 600 with thread and bracket options. Flow is published as curves rather than a single rating, so pass us your application conditions and we will confirm sizing and the complete datasheet on request.
Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J Technical Specifications
| Model | Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J |

| Port size | PT3/8" (PT thread) |
| 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) |
| Function | Oil-mist lubrication only |
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-GL30010J
| 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. |
| (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-GL30010J Is Used
Process valve actuator supply
Pneumatically actuated quarter-turn valves in a process skid cycle often and need lubricated air to keep their actuator internals healthy. The bracketless GL30010J threads directly into the actuator supply manifold on the skid.
Maintenance shop air drop
In a plant maintenance shop, 1/2 inch impact wrenches and air hammers hang off 3/8 inch drops. A GL30010J mounted directly at the drop's regulator outlet mists oil into the supply for whatever tool the technician connects.
CNC fixture clamping circuit
Pneumatic clamps and swing cylinders on a machining fixture see rapid, repetitive cycles. Installed inline on the fixture's air feed without a bracket, this lubricator keeps a steady oil mist reaching the clamp bores and seals.
Is the Airtac B52-GL Copper-Free Air Treatment Unit B52-GL30010J the Right Lubricator?
Choose the GL30010J when you need the 3/8 inch size 300 lubricator mounted without a bracket - straight onto a manifold block, a machine's air inlet or inside a cabinet where the bracket serves no purpose. For the bracketed version, order the plain GL30010. Thread is PT as the standard; G (BSPP) and NPT are catalogue options via the trailing letter. If your air consumption suggests a larger port, the same lubricator family continues in sizes 400 and 600.
Because AirTAC publishes flow as curves rather than a single rated figure, ask us to check the GL30010J against your pressure and consumption before ordering - we will confirm the datasheet on request.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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-GL30010J FAQ
AirTAC publishes lubricator flow as curves, not as one rated figure, so we do not state a single number. Give us your working pressure and required air consumption and we will confirm the correct curve and sizing from the datasheet on request before you order.
Function, size and port are identical - a size 300 lubricator with a PT3/8 port. The J suffix means this unit is supplied without a mounting bracket for direct manifold or machine mounting; the plain GL30010 includes the bracket. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options.
