Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025JNK
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR60025JNK 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-GR60025JNK
The AirTAC GR60025JNK is a pure air pressure regulator from the G-series: it reduces and holds downstream pressure only. It contains no filter, no drain bowl and no lubricator. This configuration is the largest 600 size with a 1 inch PT port, the standard pressure type (not the low-pressure L version), fitted with the K reverse/check valve and specified without a pressure gauge or mounting bracket. Maximum working pressure is 1.0 MPa (145 psi) and the adjustment range is 0.05-0.9 MPa (20-130 psi). Operating temperature is -20 to 70 C, and the medium is compressed air only.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600, so you can step port size and flow capacity up or down within the same family. Optional order codes cover G (BSPP) or NPT threads, a built-in square gauge, the K reverse/check valve, the L low-pressure type and bracket or no-bracket builds. Published flow data appears as curves rather than a single rating, so ask us and 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. |
| J | Supplied without bracket. |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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-GR60025JNK Is Used
Automotive paint spray booths
Sets a stable, reduced air pressure feeding spray guns and air-assisted atomising lines, where a steady downstream pressure keeps the coating application consistent across a shift.
Carton sealing and case packing lines
Placed at the drop to packaging machinery, it holds the working pressure for cylinder-driven tuck, fold and press stations while the built-in check valve protects the setting from downstream backflow.
Pneumatic clamping on CNC fixtures
Supplies fixture and clamp cylinders on machining centres with a controlled clamp pressure, so workholding force stays repeatable between cycles without over-pressurising the clamps.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60025JNK the Right Regulator?
Choose the 600 size with a 1 inch PT port when your main air line is that diameter and the flow demand is the largest in the G-series range; smaller 400, 300 or 200 bodies cost less but restrict higher flows. This JNK code already fixes three choices: no bracket (J), no gauge (N) and a reverse/check valve (K) that blocks reverse flow through the regulator. If you want a local pressure readout, order a GR code with a gauge instead - the embedded square gauge is standard on gauge versions, with an external round gauge available. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order.
On sizing, be aware that AirTAC publishes GR flow performance as curves, not as one rated number, so we cannot quote you a flow figure here. Send us your line pressure, set pressure and air consumption and we will confirm the correct size 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.
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-GR60025JNK FAQ
AirTAC publishes GR-series flow performance as curves, not as a single rated figure, so there is no one flow number we can honestly quote. Tell us your inlet pressure, set pressure and air demand and we will confirm the flow and sizing against the datasheet on request before you order.
For GR regulators, J means no mounting bracket, N means the unit is supplied without a pressure gauge, and K means a reverse/check valve is fitted to block backflow through the regulator. Codes without these letters come with a bracket and gauge included and no check valve.
