Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC1K
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC1K 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, 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-GR30008LC1K
The AirTAC GR series is a pure air pressure regulator: it reduces and holds a steady downstream pressure from your compressed air supply, with no filtration, no bowl and no lubrication. This GR300-08LC1K is the 300 size with a 1/4 inch PT port in the L low-pressure type, limited to a 0.4 MPa setting range for circuits that must stay at low pressure. The K suffix adds a reverse (check) valve so downstream air is held if the supply drops. An external round gauge with an MPa scale is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The G series regulators come in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, PT as standard thread with G and NPT options to order, and an operating temperature of -20 to 70 C. AirTAC publishes regulator flow as curves rather than a single rating, so we confirm the flow and datasheet figures 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. |
| (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.

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-GR30008LC1K Is Used
Hold circuit on an assembly press fixture
Maintains low set pressure to hold cylinders in a fixture, with the check valve keeping the downstream side pressurised during supply dips.
Pneumatic test rig with backflow isolation
Sets low test pressures on a QA bench while the check valve stops the tested volume pushing air back through the regulator.
Low-pressure actuation on a packaging conveyor
Feeds lightly loaded guide and divert cylinders on a conveyor line at a fixed low setting, read locally on the MPa gauge.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30008LC1K the Right Regulator?
Choose the low-pressure L type when set points sit at the low end - it is limited to 0.4 MPa by design. Add the K suffix, as here, when backflow through the regulator must be blocked. The 300 body takes a 1/4 inch PT port; move to 200, 400 or 600 for other pipework. The round gauge reads in MPa; pick the LC2K code for a psi scale. G or NPT threads are catalogue options. Flow is published as curves, not a single rating, so 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.
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-GR30008LC1K FAQ
AirTAC publishes regulator flow as characteristic curves, not as a single rated figure, so we do not quote one here. Share your set pressure and duty and we will confirm the flow from the datasheet on request.
The K adds a reverse (check) valve, so downstream air cannot push back through the regulator if the upstream supply falls. Both are the same low-pressure type, limited to a 0.4 MPa setting, with the same 1/4 inch PT port and round MPa gauge.
