The AirTAC GFR600C20C2K AirTAC Filter Regulator PT3/4 with 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 See datasheet 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 GFR600C20C2K is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is the large 600 frame with a 3/4 in PT port, a 40 um standard filtration element, and a differential-pressure automatic drain that bleeds accumulated condensate without a manual routine. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and this unit carries an external round gauge scaled in psi plus a built-in reverse (check) valve that holds downstream pressure if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (W) filtration, manual or automatic drain variants, gauge choices and G or NPT thread options. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing 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.

Point-of-use conditioning for a CNC machine shop: the 40 um element strips water and pipe scale from the plant ring main, and the regulator holds a steady setting to the machine's pneumatic valves and clamps, with the check valve holding pressure through brief supply dips.
Feeding carton sealers and case-packing cylinders on a packaging line, where the 3/4 in port suits the larger header run and the regulator keeps actuator speed consistent as other machines on the header draw air.
Conditioning the utility air drop that serves a lab's pneumatic bench equipment: filtered, regulated air at a set pressure, with the psi-scaled round gauge giving operators a direct local reading at the bench.
Step up or down through the GFR sizes (200, 300, 400, 600) to match the port and flow path your line needs; this 600 unit takes a 3/4 in PT connection. Choose the drain to suit maintenance habits: the differential-pressure drain fitted here is the default and needs no attention, while automatic (A) and manual (M) variants are available. The 40 um element fitted here suits general plant air; specify the W code for 5 um where finer protection matters. Gauge scale is selectable (MPa, psi or bar) and this unit ships with the round external gauge in psi; PT is the standard thread with G (BSPP) and NPT as order options, and a mounting bracket is included.
Because flow in this series is published as curves rather than a single rated number, 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. 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 quote a l/min or SCFM number. Tell us your application and we will confirm the datasheet flow curve and sizing for this 3/4 in, size-600 unit on request.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply drops. C2 means the external round gauge is fitted and scaled in psi. The rest of the decode: size 600, PT3/4 port, 40 um standard element, differential-pressure drain, standard regulator, bracket included.
