The AirTAC GFR60025ALF1TK AirTAC Filter Regulator 1 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a automatic 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 GFR60025ALF1TK is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 1 in NPT port for high-flow main lines, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type for circuits that run well below standard line pressure. It also carries a reverse/check valve and a square pressure gauge scaled in MPa, and includes a mounting bracket.
This is a genuine AirTAC part in the GFR family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, gauge and thread options, and reverse-valve variants. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request.

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". |
| A | Drain: Automatic 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Installed at the 1 in header feeding a bottling hall, it strips water and debris from the compressed air and holds a steady low regulated pressure to the filler and capper actuators, with automatic drainage keeping condensate off the floor.
Mounted on the branch feeding pop-up diverters and stop-gate cylinders on a parcel conveyor, it delivers clean, regulated air so the divert strokes stay consistent through each shift.
Placed on the auxiliary low-pressure line of a weaving shed, its low-pressure regulator type suits circuits that run well below standard line pressure, while the 40 um element protects the loom's pneumatic valves from water and grit.
Step up or down through the GFR sizes (200/300/400/600) against the port and flow your line needs; this unit sits at the top of the range with a 1 in NPT connection. Choose the drain to suit access: automatic (as here) for unattended condensate removal, manual for periodic service, or differential-pressure as the default. Filter grade is 40 um standard or 5 um with the W code; gauges come as the embedded square type (MPa, psi or bar scale) or an optional external round gauge; thread is PT as standard with G and NPT as orderable options; brackets can be included or omitted (J).
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your application details and we will confirm the right size 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 family as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and the equipment you are feeding, and we will confirm the flow and sizing against the datasheet on request before you order.
The A code in GFR60025ALF1TK means the bowl drains condensate automatically instead of waiting for a manual blowdown, which suits unattended plant rooms. The L code selects the low-pressure regulator type, intended for circuits that run below standard line pressure; the exact adjustment range for this type is not published in our sheet, so we confirm it on request.
