The AirTAC GFR600-20T AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit has 3/4 in NPT ports, a manual drain, a 40 um filter element, an embedded square gauge scaled in bar, and a standard regulator adjustable from 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the 600-size bowl is aluminium alloy. No mounting bracket is included.
This is a genuine AirTAC part, one of the G-series sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and PT, G or NPT threads. Across the range you can specify automatic or differential-pressure drains, the 5 um (W) filter grade, MPa, psi or bar gauge scales, and a mounting bracket. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no 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. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtering and regulating the air feeding paint guns and air-assisted applicators at a body-shop booth, where clean, dry air and a steady setpoint matter for finish quality.
Conditioning the supply to the clamp-and-press cylinders on a packaging conveyor, keeping actuator pressure consistent through a full production shift.
Supplying filtered, regulated air to quarter-turn pneumatic valve actuators on a water-treatment skid, with the bar-scaled gauge giving operators a local setpoint readout.
Port size steps with flow demand: this 600-size unit carries 3/4 in NPT ports, the largest size step in the G-series. The real choices on this model are drain type - manual here, with automatic and differential-pressure versions elsewhere in the range - the 40 um standard element versus the finer 5 um (W) grade, gauge scale (bar on this unit; MPa and psi are order options), and thread: PT is the standard, with G and NPT as catalogue options to order. A mounting bracket is not included on this configuration but is available across the range. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
This model has a manual drain: condensate is released by operating the drain by hand, which suits stations attended during routine checks. If the unit sits where nobody drains it regularly, choose the automatic or differential-pressure drain version instead.
