Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008N
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008N 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, ordered without a 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-GR20008N
The GR20008N is a genuine AirTAC G-series air pressure regulator for compressed air only. It reduces and holds a steady downstream pressure across the standard adjustment range of 0.05-0.9 MPa (7-130 psi). The N suffix means no gauge is supplied. It decodes to size 200 with PT1/4 (1/4 inch PT) ports and, with no bracket code, a mounting bracket is included; the GR series is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and pressure loss through the regulator is low.
This is a genuine AirTAC part, not a copy or a substitute. The GR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 inch to 1 inch and PT, G (BSPP) or NPT threads, with gauge options and an optional reverse (check) valve. AirTAC publishes regulator flow as curves rather than a single rated figure, so we confirm flow and datasheet 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.

| (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-GR20008N Is Used
CNC machine tool air circuit
Regulates the 1/4 inch shop-air feed to pneumatic functions on a CNC machining centre, holding a steady setpoint to the machine's air-operated components.
Bottling line capper supply
Supplies regulated air to the capper heads on a bottling line, where a stable downstream pressure keeps the capping action consistent through each shift.
Assembly bench actuators
Feeds small air cylinders and grippers at a manual assembly bench, letting operators dial in the right working pressure for light-duty tooling on a 1/4 inch line.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008N the Right Regulator?
Size 200 is the smallest step in the GR series and carries a 1/4 inch port, so it is the natural pick for compact 1/4 inch circuits. If your pipe run or air demand points to 3/8 inch or larger, step up to GR300/400/600. The standard type adjusts from 0.05 to 0.9 MPa; if your setpoint must sit well below that, the L low-pressure variant covers up to 0.4 MPa. Because this code ends in N, no gauge is supplied, so specify a square embedded gauge or an external round gauge in MPa, psi or bar scale if you want a visual setpoint reference. If an occasional upstream pressure dip would disturb your downstream setting, choose the K version with the reverse valve.
Thread is PT as the standard; G (BSPP) and NPT are catalogue options. AirTAC publishes flow for the GR series as curves, not a single rated number, so ask us to confirm sizing against the 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.
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-GR20008N FAQ
AirTAC publishes regulator flow as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Share your inlet pressure, setpoint and air demand with us and we will confirm the flow figures from the datasheet on request so you can size the unit correctly.
N means the regulator is supplied without a pressure gauge. You can still specify a gauge with the unit: an embedded square gauge or an external round gauge, with MPa, psi or bar scales available. If you want the regulator to hold its setting through upstream pressure dips, the K version with a reverse (check) valve is the alternative.
