Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40015LC1
The AirTAC B52-GR Copper-Free Air Source Treatment Unit B52-GR40015LC1 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-GR40015LC1
The GR40015LC1 is an AirTAC G-series air pressure regulator in the low-pressure type, coded L, whose setting range tops out at 0.4 MPa instead of the standard 0.9 MPa. It regulates compressed air only - no filter, no bowl, no lubricator - making it the choice for delicate circuits such as low-force actuation and pilot supplies. The configuration is size 400 with a PT1/2 port, an external round gauge on MPa scale (C1), and the mounting bracket included.
This is a genuine AirTAC part from the G series, available in sizes 200, 300, 400 and 600 with ports from 1/8" to 1". Maximum working pressure is 1.0 MPa (145 psi) and the GR operating temperature is -20 to 70 C. Because flow is published as curves rather than a single rated figure, we will confirm the datasheet numbers for this low-pressure version 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.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

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-GR40015LC1 Is Used
Lab and pilot-plant pneumatic benches
Set gentle, repeatable air pressure to test rigs and small actuators on a laboratory bench, where the MPa round gauge gives a clear readout at low settings.
Food tray sealing and tamping stations
Supply tray tamping and hold-down cylinders on a packaging line at low force, so delicate packs are pressed without crushing - a job the 0.4 MPa ceiling suits.
Air-bearing and low-force gripper supplies
Feed low-pressure air tables, air film movers and soft grippers that must not see full line pressure, with the regulator set well inside its low range.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR40015LC1 the Right Regulator?
Pick the L (low-pressure) type when your process needs fine setting below 0.4 MPa - it is the right tool when the standard 0.05-0.9 MPa range would leave you crowding the bottom of the knob. Size 400 with a 1/2" port sits mid-large in the series; go to 300/200 for branches or 600 for 3/4"-1" mains. The C1 suffix gives you the external round gauge reading in MPa; choose scale 2 for psi or 3 for bar if that is what your panel reads. Thread is standard PT, with G (BSPP) and NPT as catalogue variants, and the bracket is included in this code.
Flow data is published as curves, not a single rating, so let us confirm datasheet sizing for your application before you order.
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-GR40015LC1 FAQ
AirTAC publishes GR flow as curves rather than a single rated figure, so we do not quote a rated number for this model. Share your inlet pressure and demand and we will confirm the GR400 datasheet curve on request, including at low regulated settings.
The L code limits the adjustment range to a maximum of 0.4 MPa, giving finer, more usable setting resolution for circuits that run at low pressures. The standard GR400-15 adjusts 0.05-0.9 MPa (7-130 psi) instead. Both are regulator-only units with no filter or bowl; filtering must be done by a separate GF unit upstream.
