The AirTAC GFR600C20JC1WTK AirTAC Filter Regulator NPT3/4 5um 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 GFR600C20JC1WTK 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 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and an aluminium alloy bowl - the material used across the 600 size. The C1 suffixes add a round external pressure gauge scaled in MPa, and the K suffix fits a reverse (check) valve so downstream pressure is held if the supply is lost. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT to order), drain type, filter grade and gauge, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 a paint-line air drop: the 5 um element strips water and fine particulate before atomising equipment, while the regulator holds a steady set pressure and the check valve holds the line if supply dips.
Feeding carton-sealers and case-forming cylinders on a packaging conveyor, where the regulator keeps actuator speed consistent and the differential-pressure drain keeps condensate out of the valves without daily manual draining.
Supplying air to control-valve positioners and actuators on a process skid: clean, regulated air protects the positioner, and the reverse valve keeps the actuator's set pressure if the instrument-air header drops.
Work size and port against the air demand of the machine or line: 600 is the largest GFR size, here with a 3/4 in NPT port. Choose the drain to suit attendance: differential-pressure (this code) drains on demand, automatic drains continuously, manual requires someone to open it. Filter grade is 40 um standard or 5 um (W) where finer particulate removal is needed - this unit carries the 5 um element. Gauge scale is MPa, psi or bar (this code: round gauge, MPa), and the check valve (K) suits circuits that must hold downstream pressure. Thread is PT as standard; G (BSPP) and NPT are catalogue options - order the suffix you need. Bracket is omitted on this code (J); add it if you panel- or wall-mount. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR flow as performance curves rather than a single rated figure, so no one number exists to quote. Send us your application's air demand and we will confirm the flow and datasheet figures for this 3/4 in, size-600 unit on request before you order.
The W in the code selects the finer 5 um filter grade instead of the 40 um standard, and K fits a reverse (check) valve that holds downstream pressure if the supply is interrupted. Both are catalogue options on the GFR family; a 40 um, no-check-valve version is available if your circuit does not need them.
