The AirTAC AirTAC GFR600C20JF2WGK Filter Regulator G3/4 5 um 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 GFR600C20JF2WGK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 600 unit carries a G3/4 port with G thread, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square pressure gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting when upstream pressure is lost. It is ordered without 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 working temperature range is -5 to 70 C (non-freezing). The size 600 bowl is aluminium alloy.
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 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or external round gauges with MPa, psi or bar scales, a low-pressure regulator type, a reverse/check valve, G, NPT or PT threads, and bracket or no-bracket mounting. 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.

Point-of-use conditioning on the 3/4 inch supply feeding a CNC machining centre: the 5 um element protects solenoid valves and air bearings from particulate and water while the regulator holds a stable setting for clamping and tool-change circuits.
Conditioning the atomizing and conveying air on an industrial paint line, where the 5 um grade and automatic differential-pressure drain keep moisture and fine dirt out of spray equipment and the psi gauge gives operators a readable setpoint.
Air preparation for the pneumatic cylinders and stop-gate actuators along a bottling or canning conveyor, with the reverse/check valve holding the regulated pressure to the actuators if the upstream supply dips during a compressor switchover.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a G3/4 port, the largest step in the GFR range, suited to lines fed at 3/4 inch. Drain type is a real choice: differential-pressure (as here) drains with flow, automatic drains on a timer-free basis, and manual requires an operator to open the drain - pick per how often the line runs and how much condensate the site sees. Filter grade is 40 um standard or 5 um (code W, as here) when finer particulate protection is needed. Gauge scale is selectable (MPa, psi or bar) and the regulator can be ordered as standard or low-pressure type, with or without the reverse/check valve. Thread is PT as standard with G and NPT as order options, and the bracket can be included or omitted.
Flow for this family is published as curves, not a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm sizing and the datasheet figures 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 rated flow number. Tell us your application and required flow, and we will confirm the correct size against the datasheet curves on request before you order.
The W code in the model selects the optional 5 um filter element instead of the 40 um standard grade, for finer particulate protection downstream. The K code fits a reverse/check valve, which holds the regulated downstream pressure if upstream supply pressure is lost. Both are catalogue options you can include or omit when ordering.
