Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C1K
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C1K 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, 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-GR40010C1K
The AirTAC GR400 series is a standalone compressed-air pressure regulator - regulation only, with no filter, no bowl and no lubrication. GR40010C1K is the 400 size with a 3/8 in PT thread, standard pressure type, an external round gauge with MPa scale (C1), and the K option fitting a reverse (check) valve to hold downstream pressure if the upstream supply is lost. Adjustment range is 0.05-0.9 MPa, maximum inlet 1.0 MPa (145 psi), working temperature -20 to 70 C. A mounting bracket is included.
This is a genuine AirTAC part. The G series runs in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G and NPT as catalogue options; GR can also be panel-mounted. Flow is published as characteristic curves rather than a single rating, so we confirm datasheet and sizing figures 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.

| 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. |
| (blank) | Fixing bracket included. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

- GR400PT3/8" - PT1/2"
- GR600PT3/4" - PT1"
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-GR40010C1K Is Used
Carton erector clamp holding circuit
Keeping the flap-fold clamp pressure on an automatic carton erposer stable during header pressure dips, with the check valve holding the downstream side.
Air-spring and actuator press line
Regulating a 3/8 in feed to pressing and forming tooling that must not lose set pressure if the main supply is isolated, monitored on the round MPa gauge.
Receiver-tank-fed machine cell
Serving a small machine cell from an accumulator tank, with the regulator setting cell pressure and the check valve preventing stored air back-feeding the header.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C1K the Right Regulator?
Choose the 400 size with a 3/8 in PT port when the supply needs more capacity than the 300 series; GR600 is the next step for the largest ports. The K suffix adds the check valve for circuits that must hold set pressure through upstream dips, and C1 gives the external round gauge in MPa - psi and bar scales and the embedded square gauge are the other gauge choices. PT is standard, with G and NPT threads to order, and a bracket is included.
Sizing depends on AirTAC's flow curves rather than a single rated figure, so send us your supply pressure, set pressure and demand and we will confirm the selection against the datasheet 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.
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C1K FAQ
AirTAC publishes regulator flow as characteristic curves rather than a single rated number, so we do not quote a flow figure here. Provide your supply pressure, required set pressure and demand and we will confirm the sizing against the datasheet curves on request.
K fits a reverse (check) valve, so the downstream circuit keeps its regulated pressure when the upstream supply drops or is shut. Without the K the same 400 size, 3/8 in port and MPa round gauge configuration is ordered as the plain GR40010C1.
