The AirTAC GFR60025NWTK AirTAC Filter Regulator 1 in NPT 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 GFR60025NWTK 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 is fitted with a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a built-in reverse/check valve that holds downstream pressure when the supply is interrupted. The outlet pressure is adjusted across 0.15-0.9 MPa (20-130 psi), and the 1 in NPT port suits high-flow main-line installations. No gauge is fitted on this variant, and the size-600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, and differential-pressure, automatic or manual drains. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 1 in header drop feeding a production hall, it cleans the plant air of water and scale and holds a steady regulated pressure for every branch circuit downstream.
Feeding the air cylinders that drive pushers, diverters and stop gates on a conveyor line, where the 5 um element protects valve spools from particulate and the check valve holds position during a supply dip.
Mounted at the inlet of a distributed pneumatic panel, it gives each machine cell one filtered, regulated supply point, with the differential-pressure drain keeping condensate off the branch lines.
Step up through the GFR sizes (200 to 600) as your port and air demand grow; this size-600 unit carries a 1 in NPT port for main-line drops. Choose the 5 um element (code W) when downstream valves, cylinders or instruments need finer protection than the standard 40 um grade. The differential-pressure drain on this model needs no operator attention, but if your compressor cycles lightly or you want positive control, automatic (A) or manual (M) drain variants exist. No gauge is fitted (code N); gauges with MPa, psi or bar scales can be specified on other variants. The built-in check valve suits circuits where backflow or pressure decay on shutdown is a concern.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. 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 filter-regulator flow as performance curves rather than a single rated figure, so we do not state a flow number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The N in the code means no gauge is fitted; gauge options with MPa, psi or bar scales are available on other GFR variants. The K code means a reverse/check valve is built in, which prevents backflow and helps hold downstream pressure if the air supply is interrupted.
