The AirTAC GFR600-25T AirTAC Filter Regulator NPT1 with 5 um Filter 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 GFR600-25MC3WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 1 in NPT port, the finer 5 um filter element (code W, against the 40 um standard), a manual drain, and a round pressure gauge with bar scale. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and G/NPT thread options. Rated flow is published as curves rather than a single figure, so we confirm datasheet and flow 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. 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Feeding spray guns and booth equipment on a paint line, where the 5 um element strips water and fine particulate that would otherwise blemish the finish, and the regulator holds a steady gun supply pressure.
Supplying the cylinders and grippers on a cartoning or case-packing conveyor, with one body doing both the filtration and the pressure setting the machine's valve stack expects.
Providing clean, regulated air to quarter-turn actuated valves on a water or wastewater process skid, with the manual drain bled during routine operator rounds.
Size 600 with a 1 in port is the largest step in the GFR range; step up or down through 200/300/400/600 according to the flow your line needs, and we can check the published flow curves against your demand before you order. This unit is specified with a manual drain, which suits installations where an operator can bleed the bowl routinely and which allows the wider 0.05-0.9 MPa (7-130 psi) regulation range. The 5 um element (W) is the finer of the two grades; choose 40 um for general-duty air. The round bar-scale gauge is fitted here; an embedded square gauge with MPa, psi or bar scale is the standard alternative. Thread is NPT on this code; G(BSPP) is also a catalogue option, with PT as the standard thread. Bracket included.
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.
Flow for the GFR series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your line demand and we will confirm from the AirTAC datasheet whether this size 600, 1 in port unit is correctly sized for your application.
A manual drain means an operator opens the drain to bleed collected water, which suits attended installations on a routine round. On this unit it also permits the wider 0.05-0.9 MPa (7-130 psi) regulation range; the automatic and differential-pressure drain versions regulate across 0.15-0.9 MPa (20-130 psi).
