The AirTAC GFR60020F2G AirTAC Filter Regulator, G3/4, Square psi Gauge 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 differential-pressure 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 GFR60020F2G is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the size 600 unit with G3/4 (BSPP) female ports, the standard 40 um filter element, a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include a 5 um filter element (code W), automatic or manual drain, MPa or bar gauge scales, an external round gauge, a reverse/check valve, and NPT thread as an order alternative. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.

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.

Clean, pressure-stabilised air to spray guns and air balances in a paint booth, where water carry-over or pressure drift shows up directly in finish quality.
Feeding the pneumatic cylinders and flap-tuck actuators on a packaging conveyor, with the regulator set to the pressure the machine builder specifies.
Point-of-use conditioning ahead of a directional-valve manifold on a process line, protecting the valves from water and debris and holding a set working pressure.
Start with the size and port: 600 is the largest G-series step, with G3/4 ports, so match it to the pipe bore and the air demand of the line it feeds. Choose the drain type for the duty: this unit has the differential-pressure drain (the default, no code letter), while automatic (A) drains continuously and manual (M) requires an operator to open the drain. The standard 40 um element suits general plant air; specify 5 um (W) where finer particulate removal matters. The F2 code here means the embedded square gauge reads in psi; MPa and bar scales are available, and an external round gauge is an option. Thread is G (BSPP) on this unit; PT is the catalogue standard and NPT is an order alternative for US piping. A bracket is included; the J code omits it.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet figures and check the sizing before you order.
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 GFR series as curves, not as a single rated figure, so we do not state a number here. Ask us and we will confirm the flow curve from the datasheet and check it against your application before you order.
Yes. The F2 code on this model means the embedded square gauge is scaled in psi. Gauge scale 1 gives MPa and scale 3 gives bar, and an external round gauge is also available as an option - tell us which scale you want when ordering.
