The AirTAC GFR60025F1WTK AirTAC Filter Regulator NPT1 5um 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 GFR60025F1WTK is a 600-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is ordered with a 1 in NPT port, a fine 5 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge scaled in MPa so the setting is visible at a glance. A reverse/check valve is fitted, and the mounting bracket is included. Because this is the 600 size, the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with a regulator setting range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or external round gauges in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 drop feeding a spray booth on an automotive assembly line, it strips water and fine particulate from the plant air supply and holds a stable regulated pressure to the spray guns, protecting finish quality.
Mounted on the air preparation drop for a bottling hall conveyor, it delivers filtered, pressure-set air to the cylinder-driven stops, pushers and gating actuators that index bottles along the line.
Fitted on the supply leg of a laboratory test bench, it cleans the compressed air feeding pneumatic fixtures and holds the test pressure steady, with the MPa gauge giving the operator a direct reading of the set point.
Start with the port and size step: the 600 size carries a 1 in port, and the right step depends on the air demand of the circuit downstream - step up if your actuators or tools draw heavily, step down if the line is lightly loaded. Choose the drain to match attendance: differential-pressure (this unit) drains with flow, automatic drains on accumulation, and manual suits attended installations. Pick the filter grade for the job: 40 um is the standard element for general plant air, while the 5 um element fitted here suits finer downstream equipment. Set the gauge scale (MPa, psi or bar) to match your maintenance practice, and order PT, G or NPT thread to match the piping standard on site; a bracket is included for panel or wall fixing. Flow for this series is published as curves, not a single rated figure, so send us your application details and we will confirm the sizing against 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 no single number would be honest. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow and sizing from the datasheet for your application before you order.
The W in the code GFR60025F1WTK selects the 5 um filter grade; the blank default is 40 um. The finer 5 um element is chosen where downstream equipment - precision valves, spray equipment or instrumentation - needs cleaner air than general plant filtration provides. If your application only needs general protection, the 40 um version of the same 600-size NPT1 unit is the usual choice.
