The AirTAC GFR60020AJF2K AirTAC Filter Regulator PT3/4, 40 um 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 GFR60020AJF2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in PT port, a 40 um standard filtration element, an automatic drain that expels collected condensate without manual attention, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. The embedded square gauge reads in psi, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). The aluminium alloy bowl suits this large frame, and the unit operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for 5 um filtration (code W), manual or differential-pressure drains, gauge scale in MPa, psi or bar, G or NPT threads, and bracket mounting. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for 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.

Installed at the head of a 3/4 in distribution line serving a production hall, cleaning the compressed air of water and scale and holding a set working pressure for the whole drop network.
Feeding filtered, regulated air to the cylinders and air-operated grippers on a bottling or cartoning conveyor, with the check valve holding actuator position during brief supply interruptions.
Conditioning supply air upstream of a bank of directional control valves on an automated machine, protecting spool seats from condensate and keeping operating pressure steady for repeatable valve shifting.
Size 600 with a 3/4 in PT port is the largest step in the GFR range, so start there when the line demands high air delivery; step down to 300 or 400 if the port and flow demand are smaller. The 40 um element is the standard choice for general plant air; choose the 5 um W-grade variant where downstream valves and cylinders need finer protection. The automatic drain on this unit suits unattended or hard-to-reach installations; manual and differential-pressure drains are available if you prefer control or energy-saving purge behaviour. The square gauge here reads psi; MPa or bar scales and an external round gauge are orderable. PT is the standard thread, with G (BSPP) and NPT as order options, and this configuration ships without a mounting bracket (code J) - add one if the pipework needs support. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 performance curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the correct size and the flow data from the datasheet on request.
The A in the code GFR60020AJF2K specifies an automatic drain, which discharges collected condensate from the aluminium bowl without operator attention - useful for unattended or elevated installations. Manual (code M) and differential-pressure (blank) drains are available in the same series if you prefer to control draining yourself or save purge air.
