The AirTAC GFR60025LF2WTK AirTAC Filter Regulator NPT1 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 GFR60025LF2WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit carries a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain, a low-pressure regulator, a square gauge scaled in psi, and a built-in reverse/check valve (code K). The aluminium alloy bowl suits this largest size, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with PT, G or NPT threads, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um elements, and gauge options. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

A clean, regulated 1 in supply to air-over-oil boosters and clutch-brake circuits on a mechanical stamping press, with the check valve holding downstream pressure during supply dips.
Filtering and regulating low-pressure air for air-knife blow-off stations that dry bottles and cartons on a packaging conveyor, with 5 um filtration protecting the nozzles.
Supplying positioners and large-pneumatic-actuator control panels on a water-treatment valve skid, where the low-pressure regulator and psi gauge suit modest set-points.
Size 600 with a 1 in port is the largest step in the GFR range; step down to 300 or 400 when your line flow is smaller, and confirm the match against the published flow curve before ordering. The differential-pressure drain on this unit bleeds the bowl as pressure falls; automatic (A) and manual (M) drain codes are available if you prefer. The 5 um element (W) is the finer option against the 40 um standard, the square psi gauge is fitted, and the K code adds a reverse/check valve that holds downstream pressure if supply is lost. Thread here is NPT; PT is the standard and G is orderable. Because flow is published as curves, not a single rating, send us your flow and pressure targets and we will confirm sizing from the datasheet.
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 this series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set-point and required flow and we will confirm sizing from the datasheet on request.
K means a reverse/check valve is fitted, holding downstream pressure if upstream supply drops. The drain on this unit is differential-pressure; automatic (A) and manual (M) drain versions are available in the same series.
