Airtac B52-GL Copper-Free Air Treatment Unit B52-GL20008
The AirTAC Airtac B52-GL Copper-Free Air Treatment Unit B52-GL20008 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 B52-GL Copper-Free Air Treatment Unit B52-GL20008
GL20008 is an AirTAC G-series air lubricator: it adds a fine oil mist to the compressed air feeding downstream tools and cylinders, and does nothing else - no filtration and no pressure regulation. This 200-size unit has a PT1/4" port and, with no J suffix in the code, it includes a mounting bracket. It runs on compressed air only, accepts up to 1.0 MPa (145 psi) inlet, has a polycarbonate (PC) bowl at the 200 size, and operates at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GL family is also offered in 300, 400 and 600 sizes with larger ports up to 1", in PT (standard), G (BSPP) or NPT threads, with or without a bracket, and with aluminium alloy bowls at the 600 size. AirTAC publishes flow as curves rather than a single rating, so we confirm flow and other datasheet figures on request.
Airtac B52-GL Copper-Free Air Treatment Unit B52-GL20008 Technical Specifications
| Model | Airtac B52-GL Copper-Free Air Treatment Unit B52-GL20008 |
|---|---|
| Series | GL200 air lubricator |
| Port size | PT1/4" (PT thread) |
| Oil bowl material | PC |
| Bracket | Mounting bracket included |
| 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-GL20008
| GL200 | G-series air lubricator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (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

- 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-GL20008 Is Used
Conveyor diverter cylinders
Lubricates the air supply to gate and diverter cylinders along a sorting conveyor, so the seals on these high-cycle actuators receive a steady oil mist through every shift.
Pneumatic riveting hammer
Sits in the line feeding a riveting hammer at a metal-fabrication cell, adding the oil mist the hammer's piston and trigger valve need to keep working over long production runs.
Fixture clamp cylinders
Feeds clamp and swing cylinders on a welding fixture line with lubricated air, protecting their internal seals across thousands of clamp-unclamp cycles per day.
Is the Airtac B52-GL Copper-Free Air Treatment Unit B52-GL20008 the Right Lubricator?
GL units lubricate only, so use this one where the line already has filtration or regulation upstream, or pair it with a GF filter and GR regulator for a full three-function setup. Size: 200 covers 1/8" and 1/4" ports; move to 300 (3/8", 1/2"), 400 (3/4") or 600 (1") as flow demand grows. Bracket: included on this code; order the J version (GL20008J) to delete it. Thread: PT is the standard here, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 B52-GL Copper-Free Air Treatment Unit B52-GL20008 FAQ
AirTAC publishes flow for the GL200 series as curves, not as a single rated figure, so we do not state a number here. Give us your line pressure and air demand and we will confirm sizing against the datasheet curves on request.
GL20008 is supplied with a PT thread as the standard; G (BSPP) and NPT versions exist in the catalogue as separate codes to order. This code includes a mounting bracket, and the J version (GL20008J) is the no-bracket alternative.
