Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC4
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC4 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 PT1/8" 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-GR20006LC4
The GR20006LC4 is a genuine AirTAC G-series air pressure regulator in the compact size 200 body. It reduces and holds downstream pressure on a compressed-air line; the L code makes this the low-pressure type, so the setting is adjustable up to 0.4 MPa. The 06 position gives a PT1/8 port (PT is the standard thread for this model), and the C option specifies an external round pressure gauge. Note that scale code 4 is not one of the standard catalogue scales (1 = MPa, 2 = psi, 3 = bar), so we confirm the exact gauge scale with AirTAC before you order. There is no filter, bowl or lubricator in this unit - it regulates pressure only, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating range of -20 to 70 C (non-freezing).
Across the G-series, the GR regulator line runs from size 200 to 600 with ports from 1/8in to 1in, in standard or low-pressure versions, with or without a gauge, and with G (BSPP) or NPT thread variants, panel mounting and a reverse/check valve (K) available to order. AirTAC publishes flow as characteristic curves rather than a single rated number, so we confirm the datasheet and sizing figures for you 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.

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-GR20006LC4 Is Used
Conveyor hold-down air
Supplies the low-pressure hold-down or diverting air jets along a packaging conveyor line, keeping cartons seated without marking them.
Wire and cable blowing line
Controls the feed pressure on a small duct-blowing or cable-pushing setup where a gentle, repeatable air setting protects the jacket.
Lab pneumatic bench circuit
Feeds a laboratory bench manifold that needs a settable low-pressure air supply for fixture actuation and sample handling.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC4 the Right Regulator?
Size 200 with a 1/8in port suits compact, low-consumption circuits; step up to 300/400/600 when the line needs a larger port and more flow. The L code selects the low-pressure type, adjustable up to 0.4 MPa - order the standard GR if your settings sit in the 0.05-0.9 MPa band. The C option gives a round external gauge, but scale code 4 sits outside the standard catalogue scales (1 = MPa, 2 = psi, 3 = bar), so we confirm the exact scale with AirTAC before you order. Thread is PT as standard, with G (BSPP) and NPT as 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 (PT1/8" 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-GR20006LC4 FAQ
AirTAC publishes regulator flow as characteristic curves, not as a single rated figure, so there is no one-number rating we can quote for this model. Give us your inlet pressure, set pressure and expected air consumption and we will confirm the sizing against the datasheet curves before you order.
The code specifies a round external pressure gauge, but scale code 4 is not one of AirTAC's standard scales (1 = MPa, 2 = psi, 3 = bar). We confirm the exact fitted scale with AirTAC before your order is placed, so the gauge you receive matches the units read on your line.
