The AirTAC GFR600C20C2 AirTAC Filter Regulator 3/4 in PT 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 GFR600C20C2 is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a PT3/4 (3/4 in) PT thread port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), an external round gauge with a psi scale is fitted so the set pressure can be read directly, and a mounting bracket is included. 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. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered with manual or automatic drains, a 5 um element (code W), different gauge scales, G or NPT threads, and other catalogue options. 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.

Feeds clean, pressure-regulated air to the tool changer, clamps and pneumatic actuators on a machining center, with the 40 um element catching pipe scale and the round psi gauge letting setters verify set pressure at a glance.
Conditions the supply to diverter gates, pushers and stop cylinders along a packaging conveyor, keeping condensate and debris out of the valves while holding a stable regulated pressure for consistent cycling.
Serves drop lines at assembly stations where impact wrenches and pneumatic fixtures need filtered, regulated air, with the differential-pressure drain handling condensate between scheduled maintenance rounds.
Start with the port and size step: this unit is size 600 with a PT3/4 port, the largest step in the family, chosen when the line's required flow calls for the bigger passage - confirm the exact flow against the published curves with us before ordering. Choose the drain to match maintenance access: differential-pressure (this unit) needs no day-to-day attention, automatic drains continuously, and manual drains suit attended installations. Filter grade is 40 um as standard; specify 5 um (code W) where finer protection is needed. Gauge scale is selectable (MPa, psi or bar) - this unit ships with a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
Because flow is published as curves rather than a single rating, send us your application's flow and pressure requirements and we will confirm the correct sizing from 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 number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
The blank drain position in the code means the differential-pressure drain: condensate is discharged automatically when the pressure differential across the 40 um element rises, so there is no daily draining task. If your installation is better served by a fully automatic drain (code A) or a manual drain (code M), those are catalogue options in the same size - ask us for the matching model.
