The AirTAC GFR60020AF2WGK AirTAC Filter Regulator G3/4, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR60020AF2WGK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 unit is fitted with G3/4 ports (G/BSPP thread), 5 um filtration (the fine W grade), an automatic drain that ejects collected condensate without manual attention, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the aluminium alloy bowl suits this largest frame. Maximum inlet pressure is 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 port sizes from 1/8 to 1 inch, and options including 40 um or 5 um filtration, differential-pressure, automatic or manual drains, psi, MPa or bar gauge 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. 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.

At a large paint-line air drop, the 5 um element takes water and particulate out of the supply before atomizing equipment, while the regulator holds a steady set pressure so spray quality does not wander with plant-air swings.
On a bottling hall conveyor built around pneumatic diverters and pushers, this unit conditions the branch feed and keeps actuator pressure constant through shift-long cycling, with the automatic drain handling condensate in humid summer air.
In a machine-shop CNC cell, the G3/4 branch feeding the tool-change and clamping circuits passes through this filter regulator; the psi gauge gives the operator a visible setpoint and the check valve holds clamping pressure if the main supply drops.
Sizing a GFR starts with the port and frame: this unit is size 600 with G3/4 ports, the largest step in the family, chosen when the air demand at the point of use calls for the bigger passage. Filtration here is the 5 um W grade - pick it over the 40 um standard when downstream valves, cylinders or instruments want finer air; the trade-off is a element that loads faster. The automatic drain suits unattended installations; a manual or differential-pressure drain is the alternative where you prefer controlled or load-proportional purging. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are the other catalogue choices. Thread is G (BSPP); PT is the standard and NPT is an order option. A mounting bracket is included, and the reverse/check valve holds downstream pressure if upstream supply is interrupted.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we cannot quote you a rated flow figure here. Send us your application details and we will confirm the datasheet 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.
We do not quote a single rated flow figure, because AirTAC publishes flow for the GFR series as performance curves rather than one rated number. Tell us your line pressure and the air demand at the point of use, and we will confirm the datasheet curve and check this size against your application before you order.
The A in the code specifies an automatic drain: condensate collected in the aluminium alloy bowl is ejected on its own, so the unit suits installations that run unattended. The catalogue also offers manual and differential-pressure drains on GFR units if you prefer to purge on demand or in proportion to flow.
