The AirTAC GFR600-25 AirTAC Filter Regulator PT1 in, 5 um, psi gauge 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 GFR600-25 is a 600-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 1 in PT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and a round pressure gauge reading in psi. No mounting bracket is fitted and no reverse/check valve is included. The 600-size bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge style and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures against 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. 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.
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (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. |
| (blank) | PT 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.

Drops a 1 in plant air main down to a clean, regulated branch feeding a production cell, with the 5 um element catching fine particulate before it reaches downstream equipment.
Feeds filtered, pressure-regulated air to pneumatic actuators on a process skid, with the psi gauge giving operators a local setpoint readout at the panel.
A drop-in filter-regulator stage when reworking the air preparation section of a machine, where the manual drain suits stations that are bled down as part of a maintenance routine.
Size and port step up together: 200 through 600, with this unit at the top of the range on a 1 in PT port, so choose the size whose flow curve covers your demand rather than oversizing on guesswork. Drain type is a real decision: manual drain (this unit) needs someone to open the drain; automatic and differential-pressure drains discharge condensate without attention. The 5 um element here suits air that feeds sensitive components; the 40 um standard grade suits general supply. Gauge style is embedded square (standard) or external round with MPa, psi or bar scales - this unit has a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket can be specified where this one omits it. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from the datasheet before you order.
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 series as curves, not as a single rated number, so we do not quote a rated flow figure. Send us your required flow and working pressure and we will confirm from the datasheet whether the 600 size on a 1 in PT port covers your application before you order.
The M in the code specifies a manual drain: condensate is discharged by opening the drain by hand, which suits stations checked as part of a routine. The catalogue also offers automatic drain (code A) and differential-pressure drain (blank) on the GFR family if you want condensate handled without operator attention.
