The AirTAC GFR600-20 AirTAC Filter Regulator PT3/4, 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 GFR600-20 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This size 600 unit has a 3/4 in PT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an aluminium alloy bowl. Pressure is adjusted across 0.15-0.9 MPa (20-130 psi), a round psi gauge is fitted, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, 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.

Cleans water and debris out of the shop air and holds a steady regulated pressure feeding carton-sealing, wrapping and labelling machines on a packaging line, with the automatic drain handling condensate between shifts.
Prepares the air supply for the pneumatic cylinders that stop, divert and index product on conveyor systems, keeping grit and moisture out of valve spools while the regulator holds the setting the cylinders were set up with.
Point-of-use air preparation for CNC lathes and machining centres, where clean, dry, correctly regulated air protects clamps, tool-changers and control valves, and the psi gauge gives operators a direct pressure readout.
Size 600 with a 3/4 in PT port is the largest step in the GFR range; step down to 200, 300 or 400 where demand is smaller. Choose the drain to match the installation: automatic here, or manual or differential-pressure elsewhere in the series. The 40 um element is standard; specify W for 5 um where finer filtration matters. The gauge on this unit reads in psi (MPa and bar scales are options), and PT is the standard thread with G and NPT orderable as specifications. A mounting bracket is included. Flow is published as curves, not a single rating, so 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. 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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing from the datasheet before you order.
The automatic drain on this unit ejects collected condensate on its own, which suits installations that are hard to reach or run unattended. The same GFR600 size is also available with a manual or a differential-pressure drain if you prefer a different arrangement.
