The AirTAC GFR60020AF3T AirTAC Filter Regulator 3/4 in NPT, 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 GFR60020AF3T is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration is built for a 3/4 in NPT port, filters to 40 um as standard, and carries an automatic drain that expels collected condensate from the bowl without anyone opening it - useful on lines that run unattended. The bowl on this size is aluminium alloy, a square pressure gauge with a bar scale is fitted, and the standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with optional 5 um filtration (code W), manual or differential-pressure drain variants, gauge scales in MPa, psi or bar, an optional external round gauge, and G (BSPP) or NPT threads to order in place of the PT standard. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures against your application.

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.

Point-of-use supply for machining centres and their pneumatic clamps: the 40 um element keeps swarf-cooled shop air clean and the regulator holds a steady setting to the tool changer and clamping circuits, with the automatic drain coping between shifts.
Feeding the pick-and-place and carton-sealing cylinders on a bottling or cartoning conveyor, where a 3/4 in trunk feed serves several actuators and the automatic drain keeps condensate out of the valves on a line that runs all day.
Regulated, filtered air for lab autosamplers, pneumatic actuators and small process rigs fed from a house-air drop, where the bar-scale gauge lets technicians verify the setting and the aluminium bowl suits a fixed installation.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up or down (200/300/400/600) according to the air demand of the line rather than the pipe size alone. Choose the drain to match attendance: automatic (this unit) for unattended duty, manual where someone checks the bowl routinely, or differential-pressure as the default. Filtration is 40 um here; specify 5 um (code W) only where downstream equipment needs finer protection. The fitted square gauge reads in bar; MPa and psi scales and an external round gauge are alternatives. This unit is NPT-threaded; PT is the catalogue standard and G (BSPP) is also orderable. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so send us your flow requirement and we will confirm the right size from 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 series as performance curves rather than a single rated figure, so we do not quote a number. Tell us your required flow and operating pressure and we will confirm the correct size from the datasheet before you order.
The A in the code means an automatic drain: condensate collected in the aluminium bowl is expelled on its own, which suits unattended or hard-to-reach installations. A manual drain (code M) is the choice where someone inspects the bowl routinely, and the blank differential-pressure drain is the catalogue default.
