Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30015LC1
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR30015LC1 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 PT1/2" 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-GR30015LC1
The GR30015LC1 is an AirTAC GR-series air pressure regulator in the low-pressure type: its set pressure range goes up to 0.4 MPa, suited to circuits that must run gently rather than at full line pressure. The 300 size carries a PT1/2 port, and the LC1 suffix adds an external round pressure gauge scaled in MPa plus the standard mounting bracket. As a pure regulator it has no filter, bowl or lubricator, so it should sit downstream of a GF filter if the air also needs cleaning.
This is a genuine AirTAC part. The GR family is offered in 200, 300, 400 and 600 sizes with ports from PT1/8 to PT1, G (BSPP) and NPT thread options to order, and gauge or check-valve variants. AirTAC publishes flow only as curves rather than a single rating, so we confirm exact 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.

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-GR30015LC1 Is Used
Laboratory air supply drops
On a lab bench air manifold, the low-pressure regulator holds a gentle, stable supply to sensitive instruments and bench fixtures that must not see full shop-air pressure.
Packaging line air knives and blow-offs
Feeding air knives and blow-off nozzles on a packaging conveyor, it lets operators set a low, repeatable pressure so delicate packs and labels are cleaned without damage.
Low-pressure jig and clamp circuits
On assembly fixtures with soft-touch clamps, it supplies a fixed low pressure so parts are held securely without marking, and the round MPa gauge gives operators a clear setpoint reference.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR30015LC1 the Right Regulator?
Pick the low-pressure (L) type when your setpoint stays at or below 0.4 MPa; for setpoints up to 0.9 MPa (7-130 psi) choose the standard GR type instead. Match the size and port step (200-600, 1/8" to 1") to the air demand of the circuit. This LC1 code supplies an external round gauge on an MPa scale - if you prefer psi or bar scales, or the embedded square gauge style, those are order options. PT is the standard thread, with G (BSPP) and NPT available as catalogue options, and the bracket is included in this code. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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-GR30015LC1 FAQ
There is no single published rated-flow number for the GR series; AirTAC states flow as performance curves, which vary with pressure conditions. Send us your inlet pressure, set pressure and air consumption and we will confirm the sizing and flow from the datasheet on request.
The L type in this code limits the set pressure to a maximum of 0.4 MPa, for circuits that run at low pressures. A standard GR regulator adjusts over 0.05-0.9 MPa (7-130 psi). Choose based on your setpoint, and we can help decode the right variant.
