The AirTAC GFR600C20F2WK AirTAC Filter Regulator 3/4 in PT, 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 AirTAC GFR600C20F2WK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is built around a 3/4 in PT port, a fine 5 um filter element (the W grade, versus the standard 40 um), a differential-pressure drain that bleeds condensate as flow passes through, an embedded square gauge reading in psi, and a reverse/check valve that holds the downstream setting when upstream pressure is lost. At size 600 the bowl is aluminium alloy, and the unit carries a maximum inlet pressure of 1.0 MPa (145 psi) with a regulation range of 0.15-0.9 MPa (20-130 psi) for temperatures from -5 to 70 C, non-freezing.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, PT, G or NPT threads, and optional check valves. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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 on the 3/4 in supply drop to a machining centre, the 5 um element keeps swarf-chiller spray valves and tool-change actuators free of water and fine dirt while the regulator holds a steady setpoint and the check valve preserves it through upstream dips.
Feeding the cylinder and stopper array on a bottling or carton-packing conveyor, this unit filters condensate out of the plant air, regulates the pressure the actuators see, and its psi gauge gives the line technician a direct reading at the machine.
Mounted ahead of a valve island on an automated assembly cell, the fine 5 um grade protects solenoid seats from particulate and moisture, while the regulated output and check valve keep the island's supply stable and held during compressor unloading.
Start with the port step: size 600 with a 3/4 in PT port is the largest GFR frame, so match it to your line size and let us check the published flow curve against your air demand before you order. Choose the drain next - differential-pressure (as fitted here) drains automatically in proportion to flow, while automatic drains continuously and manual drains need periodic attention; the drain type also sets the regulation range quoted. Pick the filter grade: 40 um is the standard element and 5 um (this unit's W code) suits finer downstream equipment. Then set the gauge scale (MPa, psi or bar), the thread (PT is standard; G and NPT are order options), and whether you want the bracket (included here) and a check valve (fitted here, code K).
One honest note on sizing: AirTAC publishes GFR flow as curves, not a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing from the datasheet before you commit.
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 performance curves rather than a single rated figure, so we do not quote a flow number here. Tell us your inlet pressure, setpoint and air demand and we will confirm the sizing from the datasheet on request before you order.
The differential-pressure drain (the default, no letter in the drain position) discharges condensate automatically as air flows through the bowl, with no operator attention. The W code selects the 5 um element instead of the standard 40 um, for finer protection of downstream equipment; both grades share the same body, drain and regulation range of 0.15-0.9 MPa (20-130 psi).
