Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C1K
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C1K 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 PT1/4" 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-GR30008C1K
The AirTAC GR30008C1K is a genuine AirTAC G-series air pressure regulator: it reduces and holds a stable downstream pressure from your compressed air supply, with no filtering or lubrication function. This size 300 unit has a PT1/4 port, and the C1 in the code means an external round pressure gauge on an MPa scale is fitted, while the K suffix adds a reverse (check) valve so downstream air cannot flow back through the regulator. Regulation range is 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C.
This is a genuine AirTAC part in the GR family, which spans sizes 200, 300, 400 and 600 with 1/8" to 1" ports, optional G (BSPP) or NPT threads, round or square gauges in MPa, psi or bar scales, a low-pressure type, and a bracket for mounting. Flow figures for this series are published as curves rather than a single rating, so ask us to 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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-GR30008C1K Is Used
Pneumatic clamping on a stamping press
Sets a steady holding pressure for air-actuated clamp cylinders on a metal stamping line, so fixture force stays consistent from cycle to cycle; the check valve keeps the set pressure from bleeding back if supply dips.
Air feed to a CNC machine tool
Drops shop air to the pressure the machine builder specifies for tool-change cylinders and air-powered spindles, with a local gauge at the machine for the operator to read and adjust.
Regulating supply to a valve manifold
Feeds a bank of directional control valves on an automation panel at a controlled pressure, protecting downstream actuators and giving the panel a dedicated adjustment point.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008C1K the Right Regulator?
Step up or down in GR size (200/300/400/600) to match the port and the flow your line needs - larger sizes carry larger ports and more flow. The PT thread here is the standard; G (BSPP) and NPT versions are catalogue options to order if your pipework needs them. Choose the gauge scale you read in: this unit has a round gauge in MPa, with psi and bar scales and the embedded square gauge available on other codes, and the K option adds a reverse check valve where back-flow must be blocked. Flow in this series is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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-GR30008C1K FAQ
AirTAC publishes regulator flow as performance curves rather than a single rated number, so we do not quote a fixed figure. Ask us to confirm the flow curves and datasheet for the GR30008C1K on request, and we will help you check it against your application before you order.
The K suffix means a reverse (check) valve is fitted, which stops downstream air from flowing back through the regulator. Choose a code without K if back-flow is not a concern in your circuit; it is a real ordering choice on the GR series, not an accessory you add later.
