The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT, 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 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body, so one component does both jobs on the line. This size-600 unit is built around a 1 in NPT port, and this configuration carries a manual drain bowl in aluminium alloy, a fine 5 um filter element, a round pressure gauge reading in bar, and a reverse (check) valve fitted upstream of the regulator. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and with options for drain type, filter grade, gauge style and scale, thread form (PT standard; G and NPT to order) and bracket choice. 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. 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. |
| 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.

Feeds filtered, regulated air to the tool-change and clamping circuits of a machining centre, with the 5 um element protecting tight-tolerance valves from particles and carryover water.
Supplies the pneumatic cylinders and grippers on a carton or bottle packaging line, holding a stable working pressure so pick-and-place motions stay consistent through the shift.
Conditions the air feeding pneumatic actuated ball and butterfly valves on a process skid, with the check valve holding the set pressure if supply pressure dips upstream.
Size and port step with required flow: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range; smaller sizes (200/300/400) step down in both port and flow capacity. Drain type is a real choice: differential-pressure (default), automatic, or manual - this unit is manual, so drain it as part of routine maintenance; choose automatic or differential-pressure where the bowl cannot be reached easily. Filter grade is 40 um standard or 5 um with code W - this unit carries the 5 um element for finer protection. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit has a round gauge reading bar. Thread is PT as standard, with G (BSPP) and NPT as order options - this unit is NPT. A bracket is included; code J would omit it.
One honest note on sizing: flow is published as curves, not a single rating, so please ask us to confirm sizing against your application before ordering.
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 number, so we do not quote a figure here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The M code in GFR60025MC3WTK specifies a manual drain: condensate collects in the aluminium bowl and is released by operating the drain by hand as part of routine maintenance. The GFR series also offers an automatic drain (code A) and a differential-pressure drain (the default, no code) if the bowl is installed where manual draining is impractical.
