The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006C1K 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 PT1/8" 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.
GR20006C1K is an AirTAC G-series air pressure regulator: regulation only, with no filter element and no drain bowl. This configuration is set up for 1/8 in PT threaded ports, carries a round external pressure gauge with MPa scale, and includes a built-in reverse (check) valve that holds downstream pressure if the upstream supply drops. The regulating range is 0.05-0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C.
This is a genuine AirTAC part from the GR series, which spans sizes 200, 300, 400 and 600 so port size and capacity can step up with your line. Alternative thread options (G/BSPP or NPT), a no-gauge version, a low-pressure type and panel mounting are catalogue options. Because AirTAC publishes flow as curves rather than a single rating, we confirm the datasheet and sizing figures on request before you order.

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.

| 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.

Sets and holds the regulated pressure feeding clamping cylinders on a machining centre fixture, with the check valve keeping the clamp engaged if shop air pressure dips.
Provides a stable, adjustable pilot supply to positioners and pneumatically actuated valves on a process skid where the pilot circuit is separate from the main line.
Lets each operator on an assembly bench dial in the exact pressure for air tools and small cylinders fed from a shared 1/8 in branch line.
Size 200 with 1/8 in PT ports suits compact branch lines and small actuators; if your air demand is higher, step up to GR300, GR400 or GR600 rather than undersizing the port. The round gauge is offered in MPa (this model), psi or bar scales, so match it to the instruments already on your panel. The K option adds a reverse/check valve; choose it wherever a clamped load must not lose position if supply pressure falls. Thread is PT as standard, with G and NPT available as catalogue options, and a mounting bracket is included unless the J suffix is ordered.
Flow appears in the catalogue as curves, not one rated number, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
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 publishes regulator flow as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your line pressure and downstream demand and we will confirm the sizing from the datasheet on request before you order.
The K suffix means a reverse (check) valve is fitted. Air flows through the regulator normally, but if upstream pressure falls the check valve keeps downstream pressure from bleeding back, which is useful for clamping and holding circuits. GR models without K have no check valve.
