The AirTAC GFR600-25T AirTAC Filter Regulator, NPT1 in, 5 um 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 AirTAC GFR600-25T is a size-600 filter regulator that removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration carries a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, a round pressure gauge reading in psi, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). At size 600 the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge style and scale, and a reverse/check valve option. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing figures for your application 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| (blank) | No reverse-flow valve (the default). |
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 on a 1 in header drop feeding a production hall, it filters water and debris out of the plant air supply and holds a steady regulated pressure for the whole downstream circuit, with the manual drain emptied during daily walk-round checks.
Mounted ahead of the air lines serving clamps, tool changers and pneumatic actuators on a machining centre, the 5 um element protects valves and cylinders from particulate while the regulator holds the pressure the machine builder specified.
Fitted at the inlet of a packaging or palletising line's air distribution manifold, it conditions the supply for the line's cylinders and grippers and keeps working pressure stable as multiple stations cycle through the shift.
Start with the port step: this unit is the 1 in NPT version of the size-600 GFR, the largest in the family, so match it to your main line size and the flow your application needs - we will confirm the flow curve against your demand before you order. The 5 um element (code W) suits downstream equipment that needs cleaner air than the standard 40 um grade; the manual drain means an operator opens the drain periodically rather than relying on an automatic or differential-pressure mechanism, which suits installations that are checked as part of a routine. The round psi gauge is fitted as specified; embedded square gauges and MPa or bar scales are the other catalogue options. PT is the standard thread, with G and NPT available as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so ask us to confirm the datasheet numbers against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line size and air demand and we will confirm the flow data from the datasheet for this exact model on request.
The M in the code specifies a manual drain: an operator opens the bowl drain to release collected water, which suits installations checked on a routine; automatic and differential-pressure drains are the other catalogue options. The W code specifies the 5 um element instead of the standard 40 um grade, giving finer filtration for downstream equipment that needs cleaner air.
