Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1K
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1K 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, 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-GR30010LC1K
The GR30010LC1K is an AirTAC G-series low-pressure air pressure regulator with a reverse (check) valve fitted. The L selects the low-pressure type, whose setting range tops out at 0.4 MPa for circuits that must stay gently pressurised, while the K option allows downstream air to back-flow through the unit when the supply drops or is isolated. This LC1K configuration is the 300 size with a PT3/8 port, an external round gauge on an MPa scale, and a mounting bracket included. It regulates only - no filter and no lubricator.
This is a genuine AirTAC part. The GR series covers 200, 300, 400 and 600 sizes with standard or low-pressure types, PT/G/NPT threads, gauge and bracket choices and the check-valve K option. We confirm flow and datasheet figures for this 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.

| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge 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. |
| K | Reverse-flow (reflux) valve fitted. |
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

- 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.

Where the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1K Is Used
Paint and coating booth air
Feed atomising and agitating air to a spray booth at a limited low pressure, with the check valve letting the gun lines relax back through the regulator between coats.
Air knife and blow-off header
Set a soft, visible low pressure on the 3/8 in header feeding air knives and blow-off nozzles on a filling line, with back-flow through the check valve at line stop.
Workshop low-pressure test bench
Run a maintenance bench for checking low-pressure pneumatic devices, using the MPa gauge to set the point and the check valve to vent the device side safely at shutdown.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1K the Right Regulator?
The 300 size with its 3/8 port suits lines between the 1/4 in and 1/2 in steps of the G-series range. This code combines the low-pressure L type (settings up to 0.4 MPa) with the K check valve - a natural fit where you want both a limited setting and free back-flow at shutdown. The C1 suffix adds an external round gauge with an MPa scale; psi, bar and square-gauge variants exist if you prefer them. A mounting bracket is included, and the thread is PT as standard with G (BSPP) and NPT as catalogue options.
Because flow is published only as curves, not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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.
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30010LC1K FAQ
There is no single rated-flow figure to quote: AirTAC publishes GR regulator flow as curves. Give us your supply and setting pressures and the air your application uses, and we will confirm the flow curve and full datasheet for the GR30010LC1K on request.
L makes this the low-pressure type, adjustable up to 0.4 MPa rather than the standard 0.05-0.9 MPa range - suited to circuits that need a limited setting. K adds a reverse (check) valve so downstream air can flow back through the regulator when the upstream supply is cut. The unit is otherwise a 300-size GR with a PT3/8 port, a round MPa gauge and a bracket.
