Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40015C1
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40015C1 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 PT1/2" 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-GR40015C1
The AirTAC GR400-15C1 is a genuine AirTAC G-series air pressure regulator: regulation only, with no filter and no lubricator. This 400-size unit carries PT1/2 ports and is the standard-pressure type with an adjustment range of 0.05-0.9 MPa (7-130 psi). The C1 suffix specifies an external round pressure gauge with an MPa scale fitted, so the set outlet pressure is visible at the unit. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -20 to 70 C (non-freezing).
This is a genuine AirTAC part from the GR family, which runs 200, 300, 400 and 600 sizes across PT1/8 to PT1 ports. Options include the embedded square gauge, a low-pressure type limited to 0.4 MPa, a reverse/check valve, panel mounting and a no-bracket variant. Pressure loss on the GR is low. AirTAC publishes flow as curves rather than one rated figure, so ask us to confirm the flow and 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.

- 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-GR40015C1 Is Used
Process valve actuator supply on a skid
Regulate air to pneumatically actuated process valves on a fluid-handling skid, with the MPa gauge giving operators a local reading of the actuator supply pressure.
Bottling line clamp and lift circuits
Set controlled pressure for bottle clamps and lift stations on a bottling line so handling is gentle and consistent, with the round gauge confirming the setting at a glance.
Press fixture regulation at a fabrication cell
Feed light pneumatic press and fixture tooling at a stable set pressure so forming and staking operations repeat the same force, verified on the fitted MPa gauge.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40015C1 the Right Regulator?
At 400 size with a PT1/2 port, this is the step to take when your circuit is ported at 1/2 inch and needs the larger flow path of the 400 body; smaller circuits can drop to 200/300 and larger ones to 600. The C1 code gives you a round external gauge reading in MPa; pick the C2/C3 scale or the embedded square gauge if you prefer psi or bar or a compact panel look. A bracket is included (J would remove it) and the GR also panel-mounts. PT thread is the standard; G (BSPP) and NPT are catalogue options to state at order. Flow appears only as curves, not a single rating, so ask us to check sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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-GR40015C1 FAQ
No. AirTAC publishes GR-series flow as characteristic curves, not as one rated number, so quoting a single figure would not be accurate. We will pull the GR400-15C1 datasheet curve for your pressure conditions and confirm sizing on request before you order.
C1 fits an external round pressure gauge with an MPa scale, so you can read the regulated outlet pressure directly at the unit. The regulation itself is unchanged: standard type, 0.05-0.9 MPa adjustment, 400 size, PT1/2 PT thread, bracket included. Square-gauge or no-gauge versions are separate codes.
