Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025N
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR60025N 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, 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-GR60025N
The AirTAC GR60025N is a pure air pressure regulator from the G-series: regulation only, with no filter, no drain bowl and no lubricator. This is the largest 600 size with a 1 inch PT port, the standard pressure type, supplied with its mounting bracket and without a pressure gauge, and with no reverse/check valve. Maximum working pressure is 1.0 MPa (145 psi), the adjustment range is 0.05-0.9 MPa (20-130 psi), and operating temperature is -20 to 70 C with compressed air as the only medium.
This is a genuine AirTAC part. The GR family runs from sizes 200 through 300, 400 and 600, so the same regulator function is available in smaller port sizes if your line or flow demand is lower. Optional codes add G (BSPP) or NPT threads, an embedded square gauge, the K reverse/check valve and the L low-pressure type. Flow data is published as curves rather than a single rating, so we will confirm the datasheet and sizing 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.

| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Fixing bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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-GR60025N Is Used
Robotic gripper cells on assembly lines
Regulates supply pressure to gripper and end-of-arm actuation circuits on robot cells, where a fixed downstream setting keeps part-handling forces consistent from cycle to cycle.
Bottling line actuator air drops
Feeds bottle-washer, filler and capper stations with reduced, regulated pressure from the plant 1 inch main, with the mounting bracket used to secure the unit to the machine frame.
Truck and trailer air brake test benches
Used on workshop test rigs to set a controlled supply pressure to brake and suspension components while they are function-tested before the vehicle leaves the bay.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025N the Right Regulator?
Step up to this 600 size with a 1 inch PT port when your main air header is 1 inch and your flow demand sits at the top of the G-series range; the 400, 300 and 200 sizes suit progressively lower flows. This N code includes the mounting bracket but omits the gauge - if you want a pressure readout at the unit, order a GR60025 code without the N, which carries the embedded square gauge (an external round gauge is also optional). The blank reverse-valve position means no check valve; add K to the code if you need backflow blocked. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options to order.
Flow is published as curves, not a single rated number, so we will not quote a figure here. Share your line pressure, set pressure and air consumption and we will confirm sizing against the datasheet before you order.
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-GR60025N FAQ
AirTAC does not publish a single rated flow figure for GR regulators - performance is given as curves. That is why we do not quote a number here. Send us your inlet pressure, set pressure and air demand and we will confirm the flow and correct sizing against the datasheet on request.
N means the regulator is supplied without a pressure gauge; the mounting bracket is still included because that position is blank. If you want a local readout, order the GR60025 code without the N, which comes with the embedded square gauge, or specify the optional external round gauge.
