The AirTAC GFR60020ALC1T AirTAC Filter Regulator NPT3/4 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 GFR60020ALC1T is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit is fitted with 3/4 in NPT ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge with an MPa scale. It is the low-pressure type, and the aluminium alloy bowl suits larger-flow installations where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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. 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.

Feeds filtered, regulated low-pressure air to a bank of pneumatic actuators on a process valve skid, with the automatic drain keeping condensate out of the actuator supply during continuous operation.
Serves 3/4 in air drops serving washdown-area machinery, where the aluminium bowl and automatic drain cope with heavy condensate loading and the 40 um element protects downstream valves and cylinders.
Regulates supply pressure to air-knife and blow-off stations along a packaging conveyor, with the round MPa gauge giving operators a clear line-side pressure reading at the drop.
Start with the port step: this unit is size 600 with 3/4 in NPT threads, the largest size in the GFR range, so step down to 200/300/400 if your line uses smaller ports and lower flow. The automatic drain suits unattended duty; choose manual (M) or differential-pressure (blank) if you prefer operator-controlled or air-saver draining. The 40 um element is the standard grade; specify W for the 5 um option where finer particulate removal is needed. This is the low-pressure type (L), intended where regulated pressure sits below the standard type's range - confirm the exact range with us before ordering. The round gauge here reads in MPa; psi and bar scales are available. G and NPT threads are order options alongside the PT standard, and a mounting bracket is included.
Because flow is published only as curves and not as a single rated figure, ask us to confirm sizing against your application before you order.
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, not as a single rated figure, so we do not quote a number here. Ask us to confirm the datasheet and we will check the curve against your required flow and line pressure before you order.
The automatic drain expels collected condensate from the bowl by itself, so the unit suits unattended or continuous-duty installations without daily manual draining. The L code also makes this the low-pressure regulator type, intended for applications regulated below the standard type's range; the exact range is not published, so confirm it with us before ordering.
