Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C3
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C3 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-GR40010C3
The GR400-10 is an AirTAC G-series air pressure regulator: regulation only, with no filter bowl and no lubricator in the circuit. This size 400 unit has a 3/8 in PT port as standard, a maximum working (inlet) pressure of 1.0 MPa (145 psi) and an adjustment range of 0.05-0.9 MPa (7-130 psi). The C3 code adds an external round pressure gauge reading in bar, and the blank bracket position means a mounting bracket is included; the GR body is also panel-mountable. Operating temperature is -20 to 70 C, non-freezing, and the medium is compressed air only.
This is a genuine AirTAC part. GR regulators are available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in PT, G (BSPP) or NPT thread, with square or round gauges in MPa, psi or bar scales, and with an optional reverse/check valve (K) or no-bracket (J) build. Regulator flow is published as characteristic curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing 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.

|---|---|
| 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

| (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-GR40010C3 Is Used
CNC workholding clamps
Set and hold a stable supply pressure to the vise and clamp cylinders on a CNC machining cell so workholding stays consistent despite shop-air swings.
Packaging conveyor diverters
Feed the stopper, pusher and diverter cylinders of a packaging conveyor line from a drop point where operators can dial in the pressure the mechanism needs.
Paint booth spray air
Regulate atomizing air to spray guns in a finishing booth so gun pressure stays where the operator sets it, independent of compressor load.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40010C3 the Right Regulator?
Step up or down in size (200/300/400/600) and port (1/8 to 1 in) to match your piping and the flow curve your circuit needs; this 400 body with 3/8 in PT ports is the mid-range step of the GR series. Choose your gauge: an external round body in bar on this model, or square/round gauges in MPa, psi or bar scales elsewhere in the range. Thread is PT as the standard; G (BSPP) and NPT are catalogue options to order. Add K for a built-in reverse/check valve, or J if you do not want the bracket. Because flow is published as curves and not a single rating, send us your pressure and flow targets and we will confirm the right size before you order.
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-GR40010C3 FAQ
AirTAC publishes regulator performance as flow-characteristic curves, not as a single rated flow number, so we do not quote a figure here. Tell us your upstream pressure, set pressure and required flow, and we will confirm from the datasheet whether size 400 at 3/8 in is correct before you order.
C is the external round pressure gauge option and 3 is the bar scale, so this unit comes with a round gauge reading in bar. Square embedded gauges and MPa, psi or bar scales are available across the GR range, and G (BSPP) or NPT threads can be ordered instead of the standard PT.
