The AirTAC GFR60025F2WGK AirTAC Filter Regulator, G1 (1 in), 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 PT1" 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 GFR60025F2WGK is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This size-600 unit has a G1 (1 in) G-thread port, a 5 um filter element (code W, finer than the 40 um standard), a differential-pressure drain on the bowl, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the embedded square gauge reads in psi. The bowl on this 600 size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature 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 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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. 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.

Cleaning and regulating the air feeding paint spray booths, where the 5 um element helps keep water and particles out of the finish and the check valve holds the line setting if supply drops.
Supplying filtered, regulated air to cylinder-driven grippers and diverters on a bottling line, with the 1 in port serving a high-consumption header feeding multiple stations.
Conditioning the air that powers workholding clamps on a machining centre, where a stable set pressure from the regulator keeps clamp force consistent through the cycle.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this 600 unit carries the largest port in the family at G1 (1 in). Choose the drain to match maintenance access: differential-pressure (as here), automatic, or manual. Pick 40 um for general air prep or 5 um (this unit, code W) where finer particle removal matters. Gauge scale is selectable (MPa, psi or bar; this unit is psi, square). Thread is PT as standard with G and NPT as order options - this unit is G. A bracket is included on this configuration.
Because flow is published as curves rather than a single rating, 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 figure, so we do not quote a number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The W in the code selects the optional 5 um element, which removes finer particles than the 40 um standard. Choose 5 um where downstream equipment or the process needs cleaner air; choose 40 um for general-purpose prep. Both grades are available across the GFR range.
