Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/8" ports, ordered without a gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.

About the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN
The AirTAC GR series is a pure air pressure regulator: it reduces and holds downstream pressure from a compressed-air supply, with no filter, no bowl and no lubricator in the circuit. This GR400-10 configuration is the 400 size with 3/8 in. PT ports, standard pressure type adjustable over 0.05-0.9 MPa (7-130 psi), supplied without a mounting bracket (J) and without a gauge (N). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C.
GR400-10 is a genuine AirTAC part. The G-series regulator family runs from size 200 to 600, with larger sizes offering larger ports and more flow, thread options PT (standard), G (BSPP) and NPT, an L low-pressure version limited to 0.4 MPa, a reverse/check valve option and gauge options. GR pressure loss is low. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| GR400 | G-series pressure regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.

A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Where the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN Is Used
Packaging line air drop
Set and hold a stable working pressure on the 3/8 in. branch feeding the cylinders of a carton-sealing or case-packing machine.
Workholding clamp circuit
Adjust downstream pressure to set clamping force on a pneumatic fixture or vise at a machining cell, with the setting held at the point of use.
Machine air preparation panel
Serve as the point-of-use regulator in a machine's air preparation section, trimming supply pressure for the machine's own valves and actuators.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN the Right Regulator?
Size the GR400-10 by port and flow: the 400 body takes a 3/8 in. PT connection, and you can step down to size 300 or up to 600 as your line's capacity changes. Choose PT as the standard thread or order G (BSPP) or NPT as catalogue options; use J if you do not want the bracket, N if no gauge is needed, L for low-pressure duty up to 0.4 MPa, and K to fit a reverse/check valve. AirTAC publishes flow 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 (PT3/8" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.9 MPa (7 - 130 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010JN FAQ
AirTAC publishes GR400 flow as curves rather than a single rated figure, so we do not quote one number here. Send us your inlet pressure and downstream demand and we will confirm the datasheet flow for this size before you order.
J means this unit is supplied without a mounting bracket, and N means no pressure gauge is fitted. If you want the bracket or a gauge with an MPa, psi or bar scale, ask us for the corresponding GR400-10 code.
