The AirTAC GFR60020AC2T AirTAC Filter Regulator NPT3/4 Auto Drain 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 PT3/4" ports, a automatic 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 GFR60020AC2T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is fitted with a 3/4 in NPT port, a 40 um standard filtration element, and an automatic drain that expels collected condensate without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round external gauge reading in psi is fitted so the set pressure can be checked at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the GFR600 series, the largest size in the G-family line, which also covers 200, 300 and 400 sizes with a choice of ports, threads (PT standard, G and NPT as order options), drain types, gauge styles and scales, and a 5 um (code W) filtration element. Because rated flow is published only as curves rather than a single figure, we confirm the datasheet and flow 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.

Installed on a 3/4 in compressed-air distribution branch feeding a production hall, cleaning water and particulate from the supply and holding a steady regulated pressure for the whole downstream circuit, with the automatic drain handling condensate between maintenance rounds.
Mounted ahead of the valve manifold on a carton-forming and conveyor section, delivering filtered air at a set pressure to cylinders and grippers so case erection and product transfer run without pressure drift through the shift.
Fitted in the service-air take-off of a loading-bay rig, conditioning the supply to air-suspended dock levellers and pneumatic brake-test fixtures, with the psi gauge letting technicians verify set pressure during inspection.
Size 600 with a 3/4 in NPT port is the top of the GFR range, so step up to it when your line's required flow sits beyond what a 300 or 400 unit handles - ask us to confirm sizing against the published flow curves before ordering, since AirTAC does not publish a single rated-flow number. The automatic drain suits installations that are not checked daily; choose manual or differential-pressure drain codes if you prefer operator-controlled or pressure-differential draining. The 40 um element is the standard grade; specify the W code for 5 um where finer particulate removal is needed. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. The T suffix orders NPT threading, while PT is the catalogue standard and G (BSPP) is also available. A mounting bracket is included.
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 GFR600 series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your line pressure, set pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A code in GFR60020AC2T orders the automatic drain, which discharges collected condensate from the aluminium alloy bowl without operator attention - useful for unmanned or hard-to-reach installations. The same series is also available with manual drain (M) or the differential-pressure drain (blank code) if you prefer a different draining method.
