Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010LJC1
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010LJC1 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT3/8" ports, and ships with a pressure 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-GR40010LJC1
GR40010LJC1 is an AirTAC G-series air pressure regulator in the 400 size, fitted with a 3/8 in PT threaded port. The L in the code marks it as the low-pressure type: the regulated outlet is set up to 0.4 MPa, which suits circuits that run below the standard GR adjustment range. This configuration comes without a mounting bracket and includes an external round pressure gauge on a MPa scale.
This is a genuine AirTAC part. The GR series is offered in 200, 300, 400 and 600 sizes with a choice of PT, G(BSPP) or NPT threads, gauge styles and scales, bracket or panel mounting, and an optional reverse/check valve. It runs on compressed air only, works from -20 to 70 C, and maximum working pressure is 1.0 MPa (145 psi). AirTAC publishes flow 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.

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-GR40010LJC1 Is Used
Labeler glue applicators
Sets low, stable air pressure to glue pumps and applicator valves on a case-labeling line, where a standard regulator overshoots the working band.
Spray booth atomizing air
Feeds low-pressure atomizing air to paint spray guns in a finishing booth, giving operators a dial-in point below 0.4 MPa at the gun station.
Carton sealing clamps
Regulates hold-down clamp cylinders on a carton sealing conveyor so cartons are gripped firmly without being crushed on the line.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010LJC1 the Right Regulator?
Size 400 with a 3/8 in PT port is the upper-middle step in the GR range; step down to 300 or up to 600 when your line flow falls outside what this port size handles. As an L-type regulator the outlet is adjustable up to 0.4 MPa, so choose the standard GR version if you need settings beyond that. Gauge options are an external round or embedded square gauge on MPa, psi or bar scales, or none at all. Thread is PT as the standard, with G(BSPP) and NPT available to order, and the J code deletes the mounting bracket. AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing against the 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 - 0.4 MPa (7 - 58 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-GR40010LJC1 FAQ
AirTAC publishes GR flow as characteristic curves rather than a single rated figure, so we do not quote one number. Tell us your line flow and inlet pressure and we will confirm against the GR400 datasheet on request whether the 3/8 in port is correctly sized.
L marks the low-pressure type: the outlet is adjustable up to 0.4 MPa, instead of the 0.05-0.9 MPa range of the standard GR. Choose the standard version if your set point can go above 0.4 MPa; maximum working pressure on either type is 1.0 MPa (145 psi).
