Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1K
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1K 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-GR20008C1K
GR20008C1K is an AirTAC G-series air pressure regulator: regulation only, with no filter, no bowl and no lubricator. The 200 frame carries PT1/4 ports, and the trailing K means a reverse (check) valve is fitted in the supply path. Outlet pressure is read on a round external gauge with an MPa scale. Medium is compressed air.
This is a genuine AirTAC part. The GR series runs from size 200 to 600 with ports from 1/8 in to 1 in, PT thread as standard and G (BSPP) or NPT as catalogue options, in standard and low-pressure (L) types. Maximum working pressure is 1.0 MPa (145 psi) and the setting range for GR is 0.05-0.9 MPa (7-130 psi). Operating temperature is -20 to 70 C. Because flow is published as curves rather than a single rating, we confirm flow and other datasheet figures 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. |

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-GR20008C1K Is Used
Pneumatic clamping press
Sets and holds the working pressure on a bench pneumatic press or workholding fixture fed from a shop air main through 1/4 in drop lines, with the check valve helping hold the setting upstream.
Packaging machine actuator supply
Regulates supply to small cylinders and directional valves on a packaging or labelling machine where each station needs its own set pressure.
Pilot air for actuated valves
Regulates pilot pressure to pneumatically actuated process valves on a production skid, with the MPa gauge letting technicians set the pilot circuit at a glance.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008C1K the Right Regulator?
Real choices on this series: step through sizes 200/300/400/600 to match the port and flow duty (this unit is size 200 with 1/4 in PT ports); choose the gauge and its scale (MPa, psi or bar, round external or embedded square); order G (BSPP) or NPT threads instead of PT; specify the low-pressure L type (up to 0.4 MPa) where the line runs low; and add the K check-valve option as fitted here. AirTAC publishes GR flow as curves, not a single rated figure, so ask us to confirm sizing against the datasheet before you order.
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-GR20008C1K FAQ
AirTAC publishes GR-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the correct size and expected flow from the datasheet on request.
The trailing K means a reverse (check) valve is fitted, so air does not flow back through the regulator if upstream pressure is lost. Codes without the K are standard regulators; the rest of this code decodes as size 200, 1/4 in PT ports and a round MPa-scale gauge.
