The AirTAC GFR600C25MF1WTK 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 See datasheet ports, a differential-pressure 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 GFR600C25MF1WTK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit is threaded 1 in NPT (PT is the standard thread; G and NPT are order options - NPT is specified here). It carries the W-grade 5 um filter element (40 um is the standard grade), a manual drain on the aluminium-alloy bowl, an embedded square pressure gauge scaled in MPa, a reverse (check) valve, and the mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and options for drain type (differential-pressure, automatic or manual), filter grade (40 or 5 um), gauge style and scale, reverse valve and bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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 0.15 - 0.9 MPa (20 - 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.

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.

Point-of-use filtration and regulation on a bottling-line air ring main, delivering clean, settled-pressure air to filler valve blocks and capper clamp cylinders from a 1 in supply drop.
A filtered, regulated air drop feeding a machining cell's pneumatic clamps, tool-change cylinders and chip-ejection jets, with the 5 um element protecting fine valve spools from particulate and water.
Supplying conveyor-mounted diverters, reject pushers and bagger actuators on a packaging line, where the manual-drain bowl is emptied during scheduled changeover stops.
Choose the size step by the port and flow your line needs: this unit is 600 size with a 1 in NPT port, the largest in the GFR range, while 200/300/400 sizes step down through 1/8 to 3/4 in. Drain type is a real choice - this configuration has a manual drain, which you operate by hand; automatic and differential-pressure drains are available if the unit sits where nobody passes regularly. Filter grade is 5 um here (W code); the 40 um standard element suits general-purpose air if finer filtration is not required. The square gauge is scaled in MPa; psi and bar scales and an external round gauge are options. Thread is NPT on this unit (PT standard, G available), and the mounting bracket is included. Flow is published as curves, not a single rating - 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow and the full datasheet figures on request.
This unit is specified with a manual drain: the aluminium-alloy bowl is drained by hand, which suits attended installations or points already visited during maintenance rounds. If the unit sits where nobody passes regularly, the same 600-size filter regulator can be ordered with an automatic or differential-pressure drain instead - just ask when ordering.
