Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025C3
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR60025C3 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" 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-GR60025C3
The GR60025C3 is an AirTAC G-series air pressure regulator for compressed air only: it regulates downstream pressure and nothing else - there is no filter bowl and no lubricator in this unit. This 600-size body carries a 1 in port with PT thread, accepts up to 1.0 MPa (145 psi) of working pressure, and adjusts across the 0.05-0.9 MPa range. It is fitted with an external round pressure gauge scaled in bar, and as a GR-series regulator it operates from -20 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series regulator line runs from size 200 through 600, with PT, G (BSPP) and NPT thread options, an optional low-pressure type, an optional reverse/check valve, an embedded square gauge or an external round gauge in MPa, psi or bar scales, and bracket or panel mounting. Regulator flow is published as curves rather than a single rating, so we confirm the datasheet and flow 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (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-GR60025C3 Is Used
Textile loom plant air supply
Mounted on the branch feeds of a weaving plant's compressed-air distribution, this 1 in regulator sets loom and doffing-equipment working pressure, with the bar gauge matching the machine nameplates.
Trailer brake-test rig supply
On the shop-air feed to a commercial trailer brake-test station, it gives the technician a single adjustment point for test-line pressure, read in bar on the external round gauge.
Food plant tray-sealer pneumatics
Installed upstream of the valve stack on a tray-sealing machine's pneumatic circuit, it holds the sealing and ejection cylinders at their set working pressure from the 1 in branch line.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025C3 the Right Regulator?
At 600 size with a 1 in port, this is the largest step in the G-series; step up or down (200/300/400/600) to match the pipe and air demand of your line. For this model the real choices are: thread family (PT is the standard; G (BSPP) and NPT are catalogue options), and gauge style and scale - the C3 code selects the external round gauge with bar scale, useful where equipment nameplates are marked in bar; MPa (C1) and psi (C2) scales are alternatives. Mounting uses the optional bracket or panel mounting. Regulator flow is published as curves, not one rated number, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1" 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-GR60025C3 FAQ
AirTAC publishes regulator flow as performance curves, not as a single rated figure, so we do not quote one number here. Tell us your line pressure, downstream setting and air demand, and we will confirm the datasheet and curve figures for this exact model on request before you order.
On the GR family the gauge suffix selects the instrument: C1 is the external round gauge in MPa, C2 in psi, and C3 (this model) in bar; with no gauge code you get the embedded square gauge, and N deletes the gauge. Pick the scale that matches the rest of the panel, or N if you already have remote instrumentation.
