AirTAC GR300 · Air Pressure Regulator

Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008JC1

The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30008JC1 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 PT1/4" ports, and ships with a pressure 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-GR30008JC1

The AirTAC GR series is a pure air pressure regulator: it reduces and holds a stable downstream pressure from a compressed air line, with no filter, no drain bowl and no lubrication function. This GR30008JC1 is the 300 size with a 1/4 in PT port (PT is the standard thread; G and NPT are catalogue options), the standard pressure type with a 0.05-0.9 MPa (7-130 psi) adjustment range, and an external round gauge reading in MPa. The J code means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C (non-freezing), and the medium is compressed air only.

This is a genuine AirTAC part distributed for the US market. The G-series regulator family is offered in sizes 200, 300, 400 and 600 across a range of port sizes, with a low-pressure type option (up to 0.4 MPa), optional check valve, embedded square or external round gauges in MPa, psi or bar scale, G (BSPP) or NPT thread variants, and bracket or panel mounting. Flow capacity is published as curves rather than a single figure, so we confirm the datasheet and flow curve for your exact model 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.

Model Code: Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008JC1

GR300G-series pressure regulator, 300 body — sets the port range.
08Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2".
(blank)Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type.
JSupplied without bracket.
(blank)Pressure gauge fitted (blank).
CGauge shape: Round. C is round, F is square.
1Gauge scale: MPa. 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.

Size Class

  • GR200PT1/8" - PT1/4"
  • GR300PT1/4" - PT1/2"
  • GR400PT3/8" - PT1/2"
  • GR600PT3/4" - PT1"

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.

Maintenance shop air drops

Installed on bench drops in a maintenance area to give technicians an adjustable, gauge-monitored supply for air tools and small test jobs.

Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008JC1 the Right Regulator?

Match the 200/300/400/600 size to your port and flow demand - larger sizes carry larger ports and more flow. This configuration pairs the no-bracket J option with an external round gauge in MPa scale; psi and bar scales and a no-gauge version exist in the family. Choose PT (standard), G (BSPP) or NPT thread, and add the K check valve if the downstream side can push pressure back. Because flow is published as curves and not a single rating, send us your application parameters and we will confirm sizing against the datasheet before you order.

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 - 0.9 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-GR30008JC1 FAQ

There is no single rated flow figure to quote - AirTAC publishes regulator capacity as flow curves only. Tell us your inlet pressure and the flow your application needs, and we will confirm the sizing from the datasheet curve for this exact model on request.

J means the unit is supplied without a mounting bracket, C means an external round pressure gauge is fitted, and 1 means that gauge reads in MPa. Other family options include the embedded square gauge, psi and bar scales, and a bracket-included version.
