Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LJN
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LJN 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, ordered without a 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-GR20006LJN
GR20006LJN is an AirTAC G-series air pressure regulator: regulation only, with no filter element and no lubricator. This is the 200 size with a PT 1/8in port, the low-pressure (L) type whose setting range extends up to 0.4 MPa, supplied without a gauge (N) and without a mounting bracket (J). It reduces and holds a stable downstream pressure from a compressed-air supply, with an operating temperature of -20 to 70 C.
This is a genuine AirTAC part, bought from the catalogue as an original component. The G-series regulator line runs from size 200 up to 600, with larger port sizes, PT/G/NPT thread options, standard or low-pressure regulation, gauge and reverse-valve options, and bracket choices. Because rated flow for these units is published as curves rather than a single figure, we confirm the datasheet flow numbers 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.
Model Code: Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LJN
| 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. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class

- GR300PT1/4" - PT1/2"
- GR400PT3/8" - PT1/2"
- 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-GR20006LJN Is Used
Pneumatic clamping on a small fixture
Set and hold a low clamping pressure on an air-actuated clamp cylinder in a machining fixture, where the low-pressure (L) range up to 0.4 MPa is the working band.
Compact control panel pressure trim
Drop into a tight control cabinet or machine sub-panel as a space-saving 1/8in pressure-adjust point where no local gauge is needed at the regulator itself.
Low-pressure air feed on assembly stations
Feed light-duty pneumatic tools or small actuators on an assembly bench from a dedicated low-pressure regulated take-off point.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006LJN the Right Regulator?
The 200 size with a 1/8in port is the smallest step in the GR line, so match it to a circuit whose required flow sits comfortably in the low end of the G-series flow curves - step up to 300, 400 or 600 if your demand is higher. The low-pressure (L) type in this code covers regulation up to 0.4 MPa; if your setpoint needs more, order the standard type instead. Since this unit ships without a gauge (N), you can order a gauge-fitted variant or add an external gauge if you need a local readout; thread can be PT (standard) or G/NPT as a catalogue option.
Because AirTAC publishes flow as curves rather than a single rated number, 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-GR20006LJN FAQ
AirTAC does not publish a single rated flow figure for GR regulators - flow is given as performance curves. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this exact unit on request before you order.
The N in the code means this configuration is supplied without a gauge. You can order the same 200-size regulator in a gauge-fitted variant instead, or use an external gauge; a standard GR also offers square embedded or round external gauges on MPa, psi or bar scales.
