The AirTAC AirTAC GFR60025C3WTK Filter Regulator 1 in NPT, 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 GFR60025C3WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size-600 unit is configured with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, a round pressure gauge reading in bar, and a reverse/check valve that holds downstream pressure if the supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The aluminium alloy bowl on this 600-size unit suits installations where a polycarbonate bowl is not preferred.
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, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow for this model is published as curves rather than a single rated figure, 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.

Installed at the take-off from a plant air main, the unit cleans the supply of water and debris and sets a stable working pressure for the tools, actuators and valves served by that drop, with the check valve holding the setting through brief supply interruptions.
Feeding the air cylinders and control valves that drive diverters, gates and conveyor stops, the regulator keeps actuator speed and clamping force consistent shift after shift, while the 5 um element protects valve spools from particulate.
Mounted on the bracket ahead of pneumatic control panels and pilot-operated devices, the unit delivers filtered air at a fixed pressure, with the bar gauge giving operators a visible reference and the differential-pressure drain keeping condensate off the internals.
Start with the port and size: this unit steps up to the 600 frame with a 1 in NPT connection, the largest in the GFR range, so match it against the pipe size and air demand of the line it will feed. Filtration is set to 5 um here; choose that when downstream equipment needs finer air than the 40 um standard element delivers, noting that a finer element loads faster and relies on the drain. The differential-pressure drain is the fit-and-forget choice for lines that run continuously, while automatic and manual drains are the alternatives if your duty cycle differs. The round bar gauge is fitted as coded; square gauges and MPa or psi scales are the other catalogue options. The K code adds a reverse/check valve, and the bracket is included for panel or wall fixing. Thread is NPT as coded; PT is the catalogue standard and G (BSPP) is also orderable. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing from the datasheet before you order.
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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet curves for this 1 in NPT, 600-size unit before you order.
The W in the code selects the 5 um filter element instead of the 40 um standard, for finer protection of downstream equipment; the K code fits a reverse/check valve that holds downstream pressure if the upstream supply drops. Both are catalogue options on the GFR filter regulators, along with drain type, gauge style and scale, and thread.
