The AirTAC GFR600-20 AirTAC Filter Regulator PT3/4, 5 um, Auto Drain 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 AirTAC GFR600-20 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure across 0.15-0.9 MPa (20-130 psi) in one body. This 600-size unit is threaded PT3/4, carries a 5 um filter element (the finer of the two published grades) and an automatic drain that expels collected condensate without manual intervention. The bowl is aluminium alloy, the material used at size 600. The standard embedded square gauge is fitted with a psi scale, a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus drain, filter-grade, gauge-scale, thread (PT, G, NPT) and bracket options, so a matching unit can be specified for the rest of your circuit. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Rated flow is published only as curves, so ask us to confirm the datasheet figures 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.

Conditioning the air feed to spray guns and air bells at a paint booth: the 5 um element strips water and particulate before the gun, and the regulator holds the set gun pressure steady.
Feeding gate and stopper cylinders on a bottling conveyor with filtered, regulated air, while the fitted check valve blocks reverse flow back into the drop.
Supplying pneumatic clamps and tool-change cylinders on a CNC machining center, where the 5 um element protects downstream valves and the set regulated pressure keeps clamp force repeatable.
Step through the GFR sizes (200/300/400/600) so the port - here PT3/4 - matches your piping and the flow the circuit needs; because flow is published as curves rather than a single rating, ask us to confirm sizing against the application before ordering. This unit pairs a 5 um element with an automatic drain; the 40 um element and the manual or differential-pressure drains are the other catalogue choices. With the automatic drain the regulation range is 0.15-0.9 MPa (20-130 psi). The embedded square gauge reads in psi, and MPa or bar scales plus an external round gauge are order options. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket is included; specifying J omits it.
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 GFR flow as curves, not a single rated figure, so no rated number is quoted here. Send us your application details and we will confirm the flow and the full datasheet figures for this PT3/4 unit on request.
The automatic drain expels collected condensate on its own, so the bowl does not need manual draining. With an automatic (or differential-pressure) drain the regulation range is 0.15-0.9 MPa (20-130 psi); the manual-drain variant extends the lower end to 0.05 MPa (7 psi). The 40 um element is the other filter-grade choice.
