Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006C3
The AirTAC Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006C3 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 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-GR20006C3
GR20006C3 is an AirTAC G-series air pressure regulator: regulation only, with no filter element and no drain bowl. This configuration is set up for 1/8 in PT threaded ports and carries a round external pressure gauge with bar scale, matching equipment documented in metric units. The regulating range is 0.05-0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C.
This is a genuine AirTAC part from the GR series, which spans sizes 200, 300, 400 and 600 so port size and capacity can step up with your line. Alternative thread options (G/BSPP or NPT), a no-gauge version, a low-pressure type and panel mounting are catalogue options. Because AirTAC publishes flow as curves rather than a single rating, we confirm the datasheet and sizing figures on request before you order.

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". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

- 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-GR20006C3 Is Used
Metric-documented packaging machine retrofits
Provides a bar-readable setpoint when replacing the regulator on imported packaging machines whose manuals and dial plates are in bar.
Air knife and blow-off nozzle feeds
Lets line staff set the exact bar pressure feeding blow-off nozzles that clear chips and dust on a small machining or filling station.
Pneumatic test rigs in the workshop
Gives engineers an adjustable, bar-calibrated pressure source for bench testing pneumatic subassemblies before they go onto the machine.
Is the Airtac B52-GR Copper-Free Air Source Treatment Unit B52-GR20006C3 the Right Regulator?
Size 200 with 1/8 in PT ports fits compact branch lines and small actuators; go to GR300, GR400 or GR600 where demand is higher. The bar-scale round gauge (C3) suits machines and drawings documented in metric units; psi and MPa scales are available on other codes. Thread is PT as standard, with G/BSPP and NPT available as catalogue options, and a mounting bracket is included unless the J suffix is ordered. Add K to the code if the circuit needs a reverse/check valve fitted.
Flow is shown in the catalogue as curves, not a single rated figure, so ask us to confirm sizing against the datasheet for 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 - 0.9 MPa (7 - 130 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-GR20006C3 FAQ
There is no single rated flow to quote: AirTAC publishes regulator capacity as flow curves. Share your inlet pressure and downstream demand and we will confirm the sizing from the datasheet on request so you order the right size the first time.
C3 specifies the round external gauge with bar scale. The alternative codes on the same body are C1 (MPa scale) and C2 (psi scale). A bare code with no gauge letter still includes the standard square embedded gauge, and N deletes the gauge entirely.
