The AirTAC GFR600-20 AirTAC Filter Regulator, NPT3/4, Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600-20 is an AirTAC filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 configuration has 3/4 in NPT ports, an automatic drain on the aluminium alloy bowl, the standard 40 um filter element, an embedded square gauge with a bar scale, a fitted reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of port sizes, drain types (differential-pressure, automatic or manual), a 5 um filter element option (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow figures for your application 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 0.15 - 0.9 MPa (20 - 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Point-of-use water removal and regulated pressure for the pneumatic clamps, tool changers and actuators on a CNC machining centre fed from a shared shop-air header.
Clean, pressure-regulated air for the pick-and-place cylinders and diverters on a carton packaging conveyor, with the automatic drain coping with condensate at the drop point.
Filtered and regulated air to spray guns and air-assisted equipment in a body-shop booth, where water and particulate in the supply would otherwise reach the finish.
Size up by port and required flow: 200, 300, 400 and 600 step up in port size and capacity, so match the 3/4 in NPT port on this unit to your line size. Choose the drain to suit access: automatic (this unit) handles condensate removal at the bowl, manual suits attended installations, and differential-pressure is the default. The standard element is 40 um; specify code W for the 5 um grade where finer filtration is needed. Gauge scale is selectable (MPa, psi or bar - this unit is bar), and PT is the standard thread with G and NPT as order options; a bracket is included.
Flow for this series is published as curves, not as a single rated number, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for the GFR600-20 on request before you order.
A is the automatic drain on the bowl, F3 is the embedded square gauge with a bar scale, T is the NPT thread option (PT is the standard thread; G is also available), and K means a reverse/check valve is fitted. The filter element is the standard 40 um grade; code W would give the 5 um grade.
