The AirTAC GFR60020ALC2GK AirTAC Filter Regulator G3/4 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 GFR60020ALC2GK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 (BSPP) port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and the low-pressure regulator type for applications that work at reduced set pressures. It is fitted with an external round gauge scaled in psi, a reverse/check valve, and a mounting bracket. Because this is the 600 size, the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um (W) filtration, gauge style and scale, thread option and bracket, so a matching unit can be specified for most lines. Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet 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.

Point-of-use air at a paint line needs water and particulate stripped out and the pressure held at a low, stable setpoint before the spray equipment. A low-pressure filter regulator with automatic drain at the drop keeps the line supplied without an operator draining bowls each shift.
Carton sealers and wrap stations on a packaging line run many small actuators from one drop. Filtering and regulating the supply at the machine inlet, with a psi gauge for setpoint checks, protects the valves and cylinders from dirty air and pressure drift.
Air-operated process valves need clean, regulated air at a modest setpoint to seat and open reliably. A filter regulator mounted on the actuation skid, with a reverse/check valve holding the circuit during supply dips, gives the solenoid valves a stable feed.
Start with the port and size step: 200, 300, 400 and 600 map to increasing port sizes (1/8" up to 1"), so pick the size whose published flow curve covers your demand with margin. This unit is already the 600 size at G3/4. Drain choice matters in service: automatic drain (fitted here) suits unattended installations, manual drain suits supervised points, and the differential-pressure default is the catalogue standard. Filtration is 40 um standard; specify 5 um (code W) where downstream equipment needs finer air. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar (psi round fitted here). Thread is G (BSPP) on this unit; PT is the standard and G/NPT are order options. A bracket is included, and code J omits it.
One honest routing note: 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. 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 curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line pressure, downstream demand and allowed pressure drop, and we will confirm the datasheet curve figures for this G3/4 unit on request.
The L code in GFR60020ALC2GK selects the low-pressure regulator type, intended for circuits that operate at reduced set pressures; the exact range is not published, so confirm it with us before ordering. The C2 code fits the external round gauge scaled in psi, and the square embedded gauge scaled in MPa, psi or bar remains available as the alternative gauge option.
