The AirTAC GFR60020ALF2 AirTAC Filter Regulator PT3/4, Low-Pressure 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 GFR60020ALF2 is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your set point. This size-600 unit carries 3/4 in PT ports, an automatic drain that ejects collected condensate without operator attention, a 40 um standard filter element, and the low-pressure regulator type (the exact adjustment range for this variant is not published - we confirm it on request). The embedded square gauge reads in psi, the aluminium alloy bowl suits the larger 600 frame, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and catalogue options include manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa or bar, an external round gauge, G (BSPP) or NPT threads, and a no-bracket variant. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm sizing and the full datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Supplying filtered, regulated air to the cylinders and valves that clamp and position trim panels, with the automatic drain keeping condensate out of the circuit through continuous shifts.
Feeding the blow-off nozzles that clear film and dust from cartons on a packaging line, where the low-pressure type suits circuits set below standard regulator ranges.
Regulating shop air to the clamps and tool-change actuators on a CNC machining cell, with the 40 um element protecting downstream seals and the psi gauge giving operators a direct read.
Choose the size by port and flow: sizes 200 through 600 step up from 1/8 in to 1 in, and this 600 frame carries 3/4 in PT ports for higher-flow branches. Drain choice matters: automatic (this unit) removes condensate unattended, manual needs periodic draining, and the differential-pressure default drains only once element loading is high enough. The standard element is 40 um; specify code W for the 5 um grade where finer filtration is needed. The embedded square gauge here reads psi, with MPa and bar scales and an external round gauge as alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket can be omitted with code J. 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and downstream demand, and we will confirm the flow from the datasheet on request.
The automatic drain on this unit ejects collected condensate on its own, which suits unattended or high-humidity installations. Manual drains need periodic operator attention, and the differential-pressure default only drains once element loading is high enough. All three are catalogue options across the GFR family.
