Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60020NK
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR60020NK 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 PT3/4" 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-GR60020NK
The GR60020NK is an AirTAC G-series air pressure regulator, providing downstream pressure control only - no filtration, no bowl and no lubrication. The decode is size 600 with PT3/4 ports, mounting bracket included, no gauge, and a built-in reverse (check) valve so the regulated downstream pressure is retained if the upstream supply is shut off. Adjustment range is 0.05 to 0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GR series runs from size 200 to 600, 1/8 in to 1 in ports, PT standard with G (BSPP) and NPT options, and gauge, bracket and check-valve choices. Flow is published as curves rather than one rated number, so we confirm flow and datasheet details 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. |
|---|---|
| 20 | Port size PT3/4". 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. |
| 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-GR60020NK Is Used
Accumulation gate actuators on a packaging conveyor
Holds a fixed pressure on the gates and diverters that control product flow, and the check valve keeps the gates from drifting when the line air is isolated.
Bolt-tightening air wrench stations on a vehicle assembly line
Supplies impact wrenches and nutrunners at a controlled pressure so torque output stays within specification station to station.
Emergency hold-up circuit for a machine clamp bank
On a multi-clamp fixture circuit, the reverse valve keeps the clamped side pressurised at its set point if the main supply drops, protecting the workpiece.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60020NK the Right Regulator?
Size 600 with 3/4 in PT ports suits larger machine supply lines; sizes 200 to 400 cover 1/8 in to 1/2 in work. Pick this code over the plain GR60020N when you want the K check valve built in - it is useful on circuits where a lost supply must not vent the regulated side. The N omits the gauge; choose a gauge-coded variant if you want a built-in indication. Bracket is included. PT thread is standard, with G (BSPP) and NPT as order options; operating temperature is -20 to 70 C.
Because flow appears only as curves in the catalogue, send us your flow requirement and we will confirm the correct size on request.
Quick checklist
- ✓ Body size for your peak flow (PT3/4" 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-GR60020NK FAQ
Flow for this regulator is published as performance curves, not as a single rated number, so we do not state one here. Share your application flow and pressure and we will confirm sizing and the datasheet figures on request.
K specifies a built-in reverse (check) valve: when the upstream supply fails or is shut off, it prevents downstream air from flowing back through the regulator, holding the regulated pressure. Specify K on clamp, gate or holding circuits where that retained pressure matters.
