The AirTAC GFR60020C1TK AirTAC Filter Regulator NPT3/4 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 AirTAC GFR60020C1TK is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration carries a 3/4 in NPT port, standard 40 um filtration, a differential-pressure drain, and an aluminium alloy bowl - the material used at size 600. It is fitted with an external round gauge scaled in MPa, a 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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options including automatic or manual drains, 5 um (W) filtration, square or round gauges scaled in MPa, psi or bar, G or NPT threads, and low-pressure or reverse-valve variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet 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.

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.

Positioned at the drop to a spray booth, the unit strips water and 40 um particulate from the shop air and holds a steady regulated pressure to the guns, with the round MPa gauge giving the painter a clear setpoint readout.
On a packaging conveyor, the filter regulator feeds the flap-fold and press cylinders with clean, pressure-stable air, while the reverse/check valve helps hold the downstream circuit if upstream supply dips.
Feeding pneumatic clamps on a machining centre, the unit filters incoming shop air and regulates it to the clamp circuit's set pressure, with the bracket allowing tidy panel mounting beside the machine's valve manifold.
Start with the size and port: the 600 frame with its 3/4 in port suits the larger end of the GFR range, but the right step depends on the flow your line needs, so match the size against demand rather than port alone. Choose the drain next: this unit uses the differential-pressure drain (default); automatic (A) drains without attention and manual (M) gives operator control. Filtration is 40 um standard, with 5 um (W) available when downstream equipment needs finer air. Gauges come as an embedded square gauge or an external round gauge, scaled in MPa, psi or bar - this unit has the round MPa gauge. Thread is PT as standard with G (BSPP) and NPT as order options; this unit is NPT. A bracket is included (J deletes it), and K adds the reverse/check valve fitted here.
One honest note before ordering: flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you commit.
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 GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow figures from the datasheet for your application on request.
The differential-pressure drain is the default and works unattended, but the other options are real choices: automatic drain (code A) removes condensate without relying on a pressure differential, and manual drain (code M) lets an operator drain the aluminium bowl on demand. Pick based on how the unit is accessed in your installation; all three are available across the GFR range.
