Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60020JN
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR60020JN 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-GR60020JN
GR60020JN is a genuine AirTAC G-series air pressure regulator in the size 600 frame with a PT (standard) 3/4 inch port. It reduces and holds downstream pressure from a compressed-air supply, adjustable from 0.05 to 0.9 MPa (7 to 130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). The JN code means this unit comes without a gauge (N) and without a mounting bracket (J) - a clean, panel-mountable regulator for installations where the set pressure is read elsewhere or adjusted once and left. This regulator performs regulation only - it does not filter water or particulate and does not lubricate the air.
This is a genuine AirTAC part. The G-series regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 inch to 1 inch, with or without embedded square or round gauges on MPa, psi or bar scales, a low-pressure type, a reverse/check valve option, and G (BSPP) or NPT threads as catalogue alternatives to the standard PT. Operating temperature is -20 to 70 C. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your line size before ordering.

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. |
| 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. |
| (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-GR60020JN Is Used
Machine frame air supply without panel gauges
Regulating the 3/4 inch inlet to an OEM machine's internal air manifold where the pressure display sits on the control cabinet door, so the regulator body itself needs no gauge.
Set-and-forget auxiliary circuit feed
Feeding an auxiliary circuit such as air springs, tool clamping or actuator pilot supply that is commissioned at one pressure and rarely touched - regulation without the cost of a gauge.
Maintenance drop behind fixed plant
Installed on a maintenance air drop behind fixed plant such as a compressor-backed wash station or hoist circuit, where the technician sets pressure once and monitors it at the nearest panel gauge.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR60020JN the Right Regulator?
Take this code when your 3/4 inch line needs regulation but no local pressure display: N deletes the gauge, which suits remote-mounted sets, cabinet interiors where a gauge lives on the door, or simply a set-and-forget branch. If you want the embedded square gauge later, the F1/F2/F3 versions of the same size 600 regulator carry it in MPa, psi or bar. J omits the bracket - order one if the unit will hang off pipework, or use the panel-mount arrangement. If your port or flow is smaller than 3/4 inch, the same regulator exists at size 400 (1/2 inch), 300 (3/8 inch) and 200 (1/4 inch). Thread is standard PT, with G (BSPP) and NPT as catalogue options; a low-pressure type (L) capped at 0.4 MPa and a reverse/check valve (K) are further decodable choices. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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.
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-GR60020JN FAQ
AirTAC does not publish a single rated-flow figure for this regulator - performance is given as flow curves instead. Tell us your inlet pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
Yes - both are code-level options rather than afterthoughts. The F1, F2 and F3 versions of the same GR60020 regulator carry the embedded square gauge on MPa, psi or bar scales, and deleting the J returns a code with the mounting bracket included. The JN code itself is supplied without either.
