The AirTAC GFR600C25F2TK 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 GFR600C25F2TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit carries a 1 in NPT port, a 40 um standard filtration grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. The metal bowl (aluminium alloy at size 600) suits demanding plant environments, a square pressure gauge with a psi scale is fitted for direct setpoint reading, a reverse/check valve holds downstream pressure when the supply is lost, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drains, G or NPT thread options, and gauge or no-gauge variants. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and any datasheet figure 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 0.15 - 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.

Feeds clean, pressure-stabilised air to spray booths and air-assisted applicators, where water carryover or pressure drift would spoil finish quality on vehicle panels.
Supplies regulated air to the pneumatic cylinders that lower, hold and release cartons on a packaging conveyor, keeping stroke timing consistent across shifts.
Sits ahead of a machining centre's pneumatic clamping manifold, filtering plant air and holding a steady clamp pressure so workpieces stay secured during cutting.
Start with the port and size: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, chosen when the line's required flow sits above what smaller 200-400 bodies serve. Because flow is published as curves rather than a single rating, send us your application's flow and pressure targets and we will confirm the correct size before you order. Drain choice matters: this configuration uses the differential-pressure drain (the default); automatic (A) or manual (M) drains are available if you prefer timed or hands-on condensate removal. Filtration is the 40 um standard element; specify the W variant for 5 um where downstream equipment needs finer air. The fitted square gauge reads in psi; MPa or bar scales are alternatives. Thread is NPT here, while PT (standard) and G (BSPP) are orderable options. A bracket is included; on some families a J code deletes it.
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 filter-regulator flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application's flow and working pressure and we will confirm sizing against the datasheet curves on request before you order.
The blank drain code on this model is the differential-pressure type: condensate is discharged automatically when the pressure differential across the bowl rises, with no operator input. If you would rather have a fully automatic float drain or a manual drain you operate on a schedule, the same body is orderable with A (automatic) or M (manual) drain codes.
