Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LN
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LN 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 PT1/4" 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-GR20008LN
The GR20008LN is a genuine AirTAC G-series air pressure regulator for compressed air only, in the low-pressure type with outlet pressure adjustable up to 0.4 MPa, for circuits that run below full line pressure. It carries a PT1/4 port in the 200 size. The N means no pressure gauge is supplied, and because there is no J in the code, the mounting bracket is included, so the unit can be fixed to a machine frame or panel.
This is a regulation-only unit: no filter element, no drain bowl and no lubricator are built in. Maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and the 200 size is the most compact step in the G series, which continues through 300, 400 and 600 with larger ports and greater flow capacity. Flow data is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

|---|---|
| 08 | Port size PT1/4". 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. |
| 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.

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-GR20008LN Is Used
Machine frame air regulation
Bolted to the machine frame with its included bracket, it sets a low, stable working pressure for the actuators on one section of a production machine.
Control panel air circuit
Panel-mounted beside other air-treatment components, it drops supply pressure to a level that pneumatic pilot valves and actuators in the control circuit can safely use.
Test bench supply
Provides adjustable low-pressure air on an engineering test bench, letting the operator set different test pressures for valves and cylinders under evaluation.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20008LN the Right Regulator?
This is the PT1/4 port in the 200 size with the bracket included - choose it when you want factory mounting hardware; add the J to the code if you would rather pocket-mount the body yourself. The L type adjusts up to 0.4 MPa, so move to a standard GR if your setpoint is higher. No gauge is fitted here, so add your own downstream gauge or order a gauge-coded version (round C or square F with a 1/2/3 scale) if you want a built-in readout. Thread is standard PT; G (BSPP) and T (NPT) are catalogue options. If the 200-size flow curve does not cover your demand, step up to 300, 400 or 600. 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 (PT1/4" 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-GR20008LN FAQ
AirTAC publishes GR-series flow data as performance curves rather than a single rated flow figure, so there is no one number to quote. Give us your line pressure, target setpoint and air consumption, and we will confirm the curve data and datasheet for this 200-size, PT1/4 unit on request before you order.
It comes with the mounting bracket but without a gauge: the N in the code means no gauge is supplied, and the absence of J means the optional bracket is included. If you want a built-in readout, order a version with a gauge code - round C or square F with a 1, 2 or 3 scale - otherwise fit your own downstream gauge.
