The AirTAC GFR60020ALF3TK AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR60020ALF3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This 600-size unit is built with a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and the low-pressure regulator type for applications that call for reduced set pressures. The embedded square gauge is fitted with a bar scale, a reverse/check valve is included, and the mounting bracket ships with the unit. The 600-size bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um element, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 the gripper and clamp circuits of a robotic palletiser, where the automatic drain keeps condensate out of the valves on a line that runs unattended across shifts.
Conditioning air for conveyor-mounted diverters and pushers on a packaging line, filtering water and debris ahead of the cylinders while holding a reduced set pressure.
Supplying filtered, regulated air to the clamping fixtures of a machining cell, with the bar-scale gauge giving operators a direct read of the working pressure at the station.
Step up or down through the 200/300/400/600 size ladder against the flow your line needs - the 600 size carries the largest port in the family, here 3/4 in NPT (PT is the standard thread; G and NPT are order options). Choose the drain to match the installation: automatic drain (as fitted here) suits points where nobody walks past the unit; manual drain suits attended stations; the differential-pressure drain is the catalogue default. Element grade is 40 um as standard, with 5 um (code W) available where finer particulate capture matters. This unit is the low-pressure regulator type - confirm its exact adjustment range against your set pressure before ordering, and note the reverse/check valve is already fitted. Gauge scale here is bar; MPa and psi scales are alternatives.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet figures and the right size 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 rather than as a single rated figure, so we do not quote a l/min, SCFM or Cv number here. Tell us your application and we will confirm the datasheet flow figures and check the sizing against your demand before you order.
The A in the code GFR60020ALF3TK specifies the automatic drain, which discharges collected condensate from the aluminium bowl without operator attention - useful on unattended or overhead installations. The same GFR600 body is also available with a manual drain or the differential-pressure drain as the catalogue default; the standard filter grade is 40 um, with a 5 um element (code W) as an option.
