The AirTAC AirTAC GFR60020F1TK Filter Regulator NPT 3/4 in 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 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 GFR60020F1TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a built-in reverse/check valve that holds the downstream setting when upstream supply is lost. The set outlet pressure is read on the embedded square gauge (MPa scale), and because this is the 600 size, the 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 in to 1 in, optional 5 um filtration (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G or NPT thread options. 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.

Feeding clean, regulated air to tool changers, clamps and pneumatic actuators on a machine-tool cell, with the check valve holding actuator settings through supply dips.
Conditioning the air feeding carton sealers, case packers and bagging lines, so water and debris are stripped out and cylinders run at a stable set pressure.
Preparing air for conveyor diverters, filler heads and capping heads on a beverage line, where the differential-pressure drain keeps condensate moving without operator attention.
Start with the port and size: 600 is the largest G-series step, so size up to it when your line demand sits near the top of a smaller unit's flow curve, and down to 200/300/400 for lighter duty. Choose the drain to match access: differential-pressure (this unit) needs no attention, automatic suits unattended installations, manual suits supervised points. Pick 40 um for general air prep or the 5 um W option where finer protection matters. Select the gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order); a bracket is included on this unit.
Because flow is published as curves and not a single rating, send us your application details 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. The reflux valve permits reverse flow 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 number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The blank drain code on this model means the differential-pressure drain: condensate is discharged automatically when the pressure drop across the 40 um element rises, with no operator input. If your point of use is unattended or you prefer a scheduled manual blowdown, the GFR600 series is also available with automatic (code A) or manual (code M) drains - ask us to quote the variant.
