Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008N
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30008N 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, 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-GR30008N
GR30008N is a genuine AirTAC G-series air pressure regulator: regulation only, with no filter, no drain bowl and no lubrication function. This 300-size unit is set up with 1/4 inch PT threads, the standard adjusting range of 0.05-0.9 MPa (7-130 psi), and the N code means it is supplied without a pressure gauge - an ideal choice where the panel already carries its own gauges. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C.
This is a genuine AirTAC part, built in the same 200 / 300 / 400 / 600 size family with port sizes from 1/8 to 1 inch and optional G (BSPP) or NPT threads. The GR body is also panel-mountable and can take an optional mounting bracket. AirTAC publishes flow performance as curves rather than a single rated figure, so we confirm the exact flow and datasheet values 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". |
| (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. |
| (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.

- 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.

Where the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008N Is Used
Pneumatic clamp circuits
Set and hold the downstream pressure feeding clamping cylinders on a machining fixture, so workpieces are gripped at a repeatable set point independently of supply fluctuations.
Packaging machine actuation
Trim the pressure supplied to sealing and forming cylinders on a packaging line, keeping actuation settings stable without adding filtration the machine FRL already provides.
Branch line pressure reduction
Drop main-header pressure to a lower working level on a branch feeding a single machine or station, mounted in the branch after the plant's existing filter unit.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008N the Right Regulator?
Pick the size and port step against the air demand of the circuit: 300-size GR units with PT1/4 ports sit in the middle of the range, stepping up to 400/600 or down to 200 as the line size requires. Thread is PT as standard; G (BSPP) and NPT are catalogue options you can order. The N code deletes the gauge - if you want local pressure indication, choose a GR with a square embedded gauge or an external round gauge in MPa, psi or bar scale. A mounting bracket is included as standard; J deletes it.
Because flow data is published as curves and not as one rated number, ask us to confirm sizing against your flow demand before ordering - we will pull the GR300 datasheet figures for you.
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-GR30008N FAQ
AirTAC publishes GR300 flow performance as characteristic curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Tell us your working conditions and we will confirm the relevant flow values from the datasheet on request before you order.
N means this regulator is supplied without a pressure gauge. If you want local indication, AirTAC offers GR units with an embedded square gauge or an external round gauge, in MPa, psi or bar scale - ask us for the correct variant code.
