The AirTAC GFR60025MLF2WK AirTAC Filter Regulator PT1 Low-Pressure 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60025MLF2WK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size-600 unit is configured with a 1 inch PT port, a 5 um filter element (the finer of the two published grades), a manual drain for the bowl, a low-pressure regulator type, an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket. The 600-size bowl on this unit is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for drain type, filter grade, gauge scale, thread (PT standard, G and NPT to order), reverse valve and bracket. Flow 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. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| (blank) | PT 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.

Drops a regulated, filtered supply off a 1 inch main feeding a hall of case packers and palletisers, with the 5 um element protecting downstream valves and the psi gauge giving operators a direct readout.
Filters and regulates the air feeding pneumatic clamps and diverters along a bottling or carton conveyor line, where the manual drain suits a shift-based maintenance routine.
Supplies filtered air at reduced pressure to web-handling actuators and low-pressure blowing nozzles, with the reverse/check valve holding the circuit if upstream supply dips.
Size 600 with a 1 inch PT port is the largest step in the GFR range, so size it where your line needs the top of the family's flow capacity; the published flow data is curves, not one rated number, so send us your demand and we will confirm the fit. This unit carries the 5 um element (code W) rather than the 40 um standard - choose 5 um where downstream equipment needs finer particulate removal. The manual drain means an operator drains the bowl on a schedule rather than relying on an automatic or differential-pressure mechanism. The square gauge is scaled in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT orderable. A bracket is included, and the reverse/check valve is fitted on this code. The low-pressure regulator type suits circuits that run below standard regulating ranges; we will confirm the exact range from the datasheet on request.
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 here. Tell us your line demand and operating pressure and we will confirm the sizing against the datasheet curves before you order.
Both are decoded from the code: M is the manual-drain bowl, which an operator empties on a schedule instead of an automatic or differential-pressure drain, and W is the 5 um filter grade, the finer alternative to the 40 um standard. The 40 um and 5 um grades, and all three drain types, are orderable across the GFR range.
