The AirTAC GFR600C20ALF2WTK AirTAC Filter Regulator NPT3/4, 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 AirTAC GFR600C20ALF2WTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 3/4 in NPT port, a fine 5 um filter element (code W), and an automatic drain that expels collected condensate from the bowl without daily manual attention. The regulator is the low-pressure type, and the unit carries an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket. The bowl on size 600 units is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filter elements, and gauges scaled in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Mounted on the 3/4 in main drop feeding a stamping or assembly press valve manifold: the 5 um element removes water and fines ahead of the valves while the low-pressure regulator holds a gentle, stable supply pressure to the circuit.
Installed on the atomizing-air branch of a spray booth: the automatic drain keeps condensate out of the finish without daily bowl checks, and the low-pressure regulator suits the modest set pressures that fine atomizing air demands.
Fitted at the air-prep point for conveyor stops, gates and pusher cylinders on a bottling line: the reverse/check valve holds downstream pressure if the supply dips, and the psi-scaled square gauge gives operators a clear local setpoint readout.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest size in the GFR range - match it to your main air drop and required flow, and step down to 200/300/400 where the line is smaller. Drain type is a real choice: automatic (this unit) suits points that are hard to reach or run unattended, manual suits attended stations, and differential-pressure is the catalogue default. Filter grade is 40 um standard or 5 um (W) as fitted here for finer protection downstream. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are also selectable, and a bracket is included with this unit.
One honest routing note: AirTAC publishes flow for this family as curves, not as a single rated number, and the exact regulation range of the low-pressure type is not stated in the material we hold. Send us your line pressure, set pressure and flow demand 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 family as curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, set pressure and demand, or ask for the datasheet, and we will confirm the flow figures for this exact unit on request.
This unit's automatic drain (code A) expels condensate from the aluminium alloy bowl on its own once collected water reaches a set level, so it suits unattended or hard-to-reach installations. Manual drain (M) is emptied by hand, and differential-pressure drain is the catalogue default. Drain type is a real ordering choice across the GF/GFR/GFC/GC families.
