Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LN
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LN 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 PT3/8" 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-GR30010LN
The AirTAC GR30010LN is a low-pressure type air pressure regulator in the G series, size 300, with a 3/8 in PT thread as the standard connection. It regulates compressed air pressure only - it contains no filter element and no drain bowl, and it performs no lubrication. As the low-pressure (L) type, its adjustment range goes up to 0.4 MPa, making it the right choice where downstream equipment must be held at modest pressures rather than full line pressure.
This is a genuine AirTAC part, supplied with a mounting bracket as standard. The GR family spans sizes 200, 300, 400 and 600 with a range of port sizes and PT, G (BSPP) or NPT thread options. Published flow data appears as curves rather than a single rating, so we confirm exact flow and datasheet figures 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. |
|---|---|
| 10 | Port size PT3/8". 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-GR30010LN Is Used
Air-jet loom supply
On a weaving shed's air-jet looms, the GR30010LN holds the low main-jet pressure the loom control system calls for, stepping shop air down instead of letting full line pressure reach the nozzles.
Paint spray booth lines
At a spray booth manifold feeding gravity-feed guns, the low-pressure type regulator lets finishers set a gentle, stable atomizing pressure below 0.4 MPa at each 3/8 in drop.
Tray-sealing machine
On a food packaging tray sealer, the regulator supplies the soft pressing and film-tension circuits at low pressure, keeping delicate trays from being crushed during the seal cycle.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LN the Right Regulator?
The main decodable choices on this regulator are size and port, thread style, pressure class and gauge. This unit is size 300 with a 3/8 in PT port - step up to size 400 or 600, or to a larger port, when your line requires more flow capacity. Because it carries the L code, it is the low-pressure type with adjustment up to 0.4 MPa; if your process needs the full 0.05-0.9 MPa range, order the standard GR type instead. The N code means no gauge is fitted, and this configuration omits the J code, so a mounting bracket is included. PT is the standard thread; G and NPT are catalogue options you can specify when ordering.
Flow for the GR series is published as curves, not a single rated number. Ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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-GR30010LN FAQ
AirTAC publishes GR-series flow as characteristic curves rather than one rated number, so we do not quote a single figure on the page. Tell us your working pressure and demand and we will confirm the sizing from the datasheet curves before you order.
The L code makes this the low-pressure type, with adjustment up to 0.4 MPa instead of the standard 0.05-0.9 MPa range. It suits circuits such as spraying, jetting and light clamping that must never see full regulated pressure. If you need the wider range, order the standard type.
