The AirTAC GFR60020C2GK AirTAC Filter Regulator G3/4 with 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 GFR60020C2GK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is the large 600 size with a G3/4 (BSPP) port, standard 40 um filtration, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an aluminium alloy bowl suited to this top size. A round external gauge reading in psi is fitted, and the K code means a reverse/check valve is built in so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will 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.

Installed at the 3/4 inch main drop from a plant compressor receiver, it strips water and pipe-scale from the supply and holds a steady regulated pressure for the whole workshop ring, with the check valve protecting the circuit if the compressor unloads.
Feeding the pneumatic cylinders on a carton-forming and sealing conveyor, it keeps the air clean and the pressure constant so clamp and pusher strokes repeat consistently through each shift.
On a CNC fixture clamping circuit, it filters the shop air to protect the clamping valves and holds the regulated pressure the fixture designer specified, with the psi gauge giving the operator a direct reading at the machine.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; the 600 here takes a 3/4 inch port. Choose the drain to match maintenance access: differential-pressure (this model, no operator action), automatic for continuous unattended draining, or manual where you want controlled purging. Filtration is 40 um standard; specify the W code for 5 um if downstream equipment needs finer protection. Gauges come as an embedded square unit or an external round unit, in MPa, psi or bar scales - this model carries the round psi gauge. Threads are PT as standard with G (BSPP) and NPT as order options; the G here is a specification choice, not a delivery statement. Brackets are included on GFR units. Because flow is published as curves rather than one rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, working pressure and expected air demand, and we will confirm the datasheet flow figures for this exact model on request before you order.
The C2 code in GFR60020C2GK specifies the external round gauge with a psi scale; the embedded square gauge in MPa, psi or bar scales is the alternative. The trailing K specifies a built-in reverse/check valve, which holds downstream pressure if the upstream supply is interrupted. Both are decode choices you can order with or without.
