Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LN
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LN is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/4" 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-GR30008LN
GR30008LN is an AirTAC G-series air pressure regulator in the 300 size with a PT1/4 port. It reduces and holds downstream air pressure for compressed-air circuits, and the L in the code identifies the low-pressure type, with set pressure adjustable up to 0.4 MPa for circuits that must not see full line pressure. The bracket position is blank, which in the AirTAC code means a mounting bracket is included, and the N suffix means no gauge is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and the medium is compressed air only.
This is a genuine AirTAC part. The G-series regulator family runs in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, in PT (standard), G (BSPP) or NPT thread, with or without gauge, bracket or reverse/check valve; GR is also panel-mountable. AirTAC publishes regulator flow as performance curves rather than a single rated figure, so ask us to confirm flow and datasheet details 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.

| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 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-GR30008LN Is Used
Regulating stage on maintenance rigs
Used as the pressure-setting stage on a mobile pneumatic maintenance rig, with the included bracket fixing the unit firmly to the rig panel.
Workshop air-tool bench stations
Mounted on a workshop wall with its bracket, it drops line air to a reduced working pressure for hand-held air tools at a bench outlet.
Machine air supply drops
Installed at the air drop feeding a packaging machine section, holding a low set pressure for actuators downstream that cannot tolerate full line pressure.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LN the Right Regulator?
Start with the port: the 300 size in this code carries a PT1/4 port; step up to the 400 or 600 sizes for larger ports and more air, or down to 200 for compact circuits. The L code makes this the low-pressure type, with set pressure adjustable up to 0.4 MPa; if your process needs the full 0.05-0.9 MPa range, choose the standard GR300-08 instead. The blank bracket code means a mounting bracket is included - add J to the code if you want the unit without one - and the N code deletes the gauge; gauge variants with square or round dials in MPa, psi or bar exist in the family. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. Because AirTAC publishes regulator flow only as curves, not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 - 0.4 MPa (7 - 58 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-GR30008LN FAQ
AirTAC publishes regulator flow as performance curves rather than a single rated figure, so no flow number is quoted here. Share your inlet pressure, set pressure and air consumption and we will confirm the GR300 sizing from the datasheet on request.
Yes - the bracket position is blank in this code, which in the AirTAC scheme means a bracket is included, and the GR series is also panel-mountable. Adding J to the code removes the bracket. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options.
