The AirTAC Airtac B52-GL Copper-Free Air Treatment Unit B52-GL40015J 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 PT1/2" 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.
The AirTAC GL40015J is a G-series air line lubricator: it meters an oil mist into the compressed air supply so downstream cylinders, valves and air tools receive continuous lubrication. It performs lubrication only - no filtration and no pressure regulation. This size 400 configuration carries a PT1/2 port and a polycarbonate bowl, and the J suffix means the mounting bracket is omitted, keeping the footprint minimal for direct manifold or frame mounting. Maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series lubricator family runs from size 200 through 600, with PT as the standard thread and G (BSPP) and NPT as catalogue options. Published flow data appears as curves rather than a single rated figure; ask us and we will confirm the datasheet figures for your application on request.

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.
| GL400 | G-series air lubricator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 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.
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.

| Line order | Filter first, then regulator, lubricator last |
Plumbed directly into the manifold of a multi-station assembly fixture panel, the GL40015J lubricates the supply air feeding clamps and cylinders at every station without adding a bracket to the panel layout.
On a pneumatic gantry used for material handling, the lubricator feeds the linear actuators and gripper cylinders from a 1/2-inch line, keeping their seals lubricated through high-cycle pick-and-place duty.
Installed in the airline serving yarn-threading and doffing cylinders on a textile machine, the GL40015J delivers a steady oil mist so the machine's pneumatic components run lubricated in dusty continuous operation.
Choose the GL40015J over the GL40015 when the bracket is not needed - the unit mounts straight onto a manifold, bulkhead or existing panel. The PT1/2 port is the larger port in the size 400 frame; pick it for 1/2-inch piping or when you want lower pressure drop than the PT3/8 version. Thread is PT standard, with G (BSPP) and NPT available to order.
Because flow is published as curves rather than a single rated figure, send us your operating conditions and we will confirm sizing against the datasheet before you order.
Quick checklist
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.
No single rated flow figure exists to quote: AirTAC publishes lubricator flow as curves in the datasheet. Share your line pressure and the flow your actuators require, and we will confirm the sizing from the datasheet on request before you order.
The J suffix means no mounting bracket is supplied - the unit is otherwise the same size 400, PT1/2, polycarbonate-bowl lubricator as the GL40015. It suits direct manifold, bulkhead or panel mounting. Order the plain GL40015 if you want the bracket included.
