Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30015C1K
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30015C1K 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-GR30015C1K
GR30015C1K is an AirTAC G-series air pressure regulator: regulation only, with no filter bowl and no lubricator. This size 300 unit carries a 1/2 in G(BSPP) female thread, the C1 suffix specifies an external round pressure gauge with MPa scale, and the K suffix means a built-in reverse (check) valve is fitted. The standard-type regulator adjusts outlet pressure across 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), on compressed air only, with an operating temperature of -20 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series regulator range runs from size 200 to size 600 with ports from 1/8 in to 1 in, and options include PT (standard), G or NPT threads, embedded square or external round gauges with MPa, psi or bar scales, a low-pressure type rated up to 0.4 MPa, and the K reverse (check) valve shown here. A bracket is included. Flow data is published as curves rather than a single rating, so ask us to confirm 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.
Model Code: Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30015C1K
| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 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. |
| (blank) | Pressure gauge fitted (blank). |
| 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.
Size Class

- GR300PT1/4" - PT1/2"
- 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-GR30015C1K Is Used
Pneumatic press supply
Regulating the air to a small pneumatic press or clamping fixture, where the fitted reverse valve backs up the circuit against downstream back-flow.
Control panel air supply
Feeding instrument and control cabinets that use air-actuated components, with the round MPa gauge giving a clear local set-pressure reading.
Trailer air-powered equipment
Supplying air-powered tail-lift and dock equipment built to BSPP fittings, holding a steady working pressure from the vehicle's supply line.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30015C1K the Right Regulator?
Match the size code (200/300/400/600) to the port and flow your circuit needs; size 300 with its 1/2 in port is the mid-range step. Choose the gauge: embedded square or this external round type, with MPa (1), psi (2) or bar (3) scales. PT thread is the standard build; G(BSPP) and NPT are catalogue options to order. Decide on the K suffix: this unit carries the reverse (check) valve, while the same code without K leaves it out. Flow is published as curves, not a single rating, so send us your flow and pressure conditions and we will confirm sizing against the datasheet before you order.
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.
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-GR30015C1K FAQ
Flow for this series is published as curves, not as a single rated figure, so we do not state a number here. Share your inlet pressure, set pressure and demand, and we will confirm the sizing from the datasheet on request.
K specifies that a built-in reverse (check) valve is fitted. The same regulator without the K suffix (a blank in that position) is supplied without the valve - choose the K version only if your circuit calls for it.
