Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC1K
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC1K 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-GR20006LC1K
GR20006LC1K is a genuine AirTAC G-series air pressure regulator for compressed air only, in the low-pressure type (code L) with a setting range up to 0.4 MPa. The code decodes to a size 200 unit with a 1/8in PT-thread port (PT is the standard thread; G and NPT are orderable options), an external round pressure gauge with MPa scale (code C1), the mounting bracket included, and a reverse (check) valve fitted (code K). Maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -20 to 70 C. Pressure loss through the GR series is low.
The G-series regulator line is available in sizes 200, 300, 400 and 600, stepping ports from 1/8in to 1in. Options include standard or low-pressure type, with or without the K reverse valve, no gauge, embedded square gauges, or external round gauges in MPa, psi or bar scales, and G or NPT threads. AirTAC publishes flow as curves rather than a single rating, so we confirm datasheet figures 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.

| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| 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-GR20006LC1K Is Used
Low-pressure glue or coating line
Holds a low, gauge-checked setting to a glue or coating head while the fitted check valve stops the circuit back-feeding through the regulator.
Sample-holding test bench
Sets a low test pressure on a bench rig and holds it against reverse flow once the supply side is closed.
Delicate actuator feed on a packaging line
Feeds low-pressure sealing or labelling cylinders with a round-gauge setting and a check valve holding the set circuit pressure.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LC1K the Right Regulator?
This build combines the low-pressure type (L, setting up to 0.4 MPa), an external round MPa gauge (C1), the included bracket, and a fitted reverse (check) valve (K) for circuits that must hold pressure against backflow. Size 200 with a PT1/8in port suits the smallest lines; GR300/400/600 step up to 1/4in-1in ports for more flow. Order C2/C3 gauges for psi or bar scales, or G/NPT threads instead of PT.
Flow is published as curves, not as one rated figure, so ask us to confirm the datasheet data 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.
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-GR20006LC1K FAQ
There is no single rated flow figure: AirTAC publishes GR-series flow as performance curves rather than a number. We do not quote a rating here, but we will confirm the flow and datasheet data for your application on request before ordering.
Both are low-pressure (L) regulators with an external round MPa gauge and bracket. The K suffix adds a fitted reverse (check) valve, which is the right choice where downstream pressure must not feed back through the regulator, such as clamping, holding or test circuits.
