The AirTAC GFR60020F2WK AirTAC Filter Regulator PT3/4, 5 um 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 differential-pressure 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 GFR60020F2WK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a PT3/4 port, a 5 um filter element (the finer W grade, versus the standard 40 um), a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when upstream supply is lost. The aluminium alloy bowl on this size 600 unit suits heavier-duty installations, and the included mounting bracket simplifies panel or frame fixing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain, filter-grade, gauge-scale and thread options, so a variant can be matched to most line requirements. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Feeds filtered, regulated air to tool-changer and clamping actuators on a machining centre, with the 5 um element protecting precision valve spools and the check valve holding clamp pressure through supply dips.
Conditions the atomising air line at a spray booth: the 5 um grade keeps water and particulate out of the finish, and the regulator holds a steady set pressure so the gun delivers a consistent pattern.
Supplies the pneumatic diverters, pushers and sealing jaws on a packaging conveyor, with the square psi gauge giving operators a visible setpoint and the differential-pressure drain keeping condensate off the valves.
Size and port are the first choice: the 600 frame with its PT3/4 connection is the largest GFR step, so size up from 400 when your line's flow demand outgrows the smaller ports - we will confirm the flow curve against your requirement on request. This unit's W code gives the 5 um element; choose it where downstream valves, cylinders or instruments need finer filtration than the standard 40 um grade, accepting that a finer element loads faster and needs the drain working well. The differential-pressure drain here is the fit-and-forget option; a manual drain (M) suits intermittent duty where someone walks the line, and an automatic drain (A) suits unattended pits or hard-to-reach mounts.
The F2 code means the embedded square gauge reads in psi - bar and MPa scales are available if your team works metric. The K code adds a reverse/check valve, worth specifying when a cylinder or clamp must hold position through a supply dip. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order for other piping standards. The bracket is included on this code; J variants omit 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Send us your line demand and we will confirm the flow curve and sizing from the datasheet before you order.
The W code selects the optional 5 um filter grade instead of the standard 40 um element, for finer protection of downstream equipment. The K code adds a reverse/check valve, which holds downstream pressure if the upstream supply drops. Both are decodable choices on the GFR range; the standard alternative is the 40 um element with no check valve.
