The AirTAC GFR600C25F1TK 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 GFR600C25F1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port for high-flow lines, 40 um standard filtration, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, a fitted reverse/check valve, and a mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with a regulation range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 40 um standard or 5 um (code W) filter grade, gauge and scale options, PT as the standard thread with G and NPT as order options, and bracket choices. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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 0.15 - 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.

Installed at a 1 in branch take-off from a factory compressed-air ring main, it filters carryover water and particulate and holds a set downstream pressure for an entire production bay.
Feeding a pneumatic press or clamping station, the unit strips condensate and chips from the shop air and regulates the pressure the cylinder circuit actually sees, protecting the tooling sequence.
On a packaging line running air cylinders, diverters and gate actuators, the filter regulator conditions the supply and keeps actuator pressure steady so indexing and product stops stay repeatable.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - the 1 in port of this size 600 unit suits the largest branch circuits in the GFR range. Choose the drain to match maintenance routines: differential-pressure (this unit) drains with flow, automatic drains on a timer-free basis, and manual drain suits attended stations. Pick 40 um for general air preparation or the 5 um (W) element where finer particulate removal matters. Select the gauge scale (MPa, psi or bar) and thread (PT standard; G or NPT to order); a bracket is included here.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet curves 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 family as performance curves rather than a single rated figure, so we do not state a flow number here. Tell us your application and operating pressure and we will confirm the relevant datasheet curve figures for you on request.
This unit has the differential-pressure drain, which discharges collected condensate automatically as air flows through - a good fit for lines with steady demand. An automatic drain (code A) suits intermittent-flow lines, and a manual drain (code M) suits attended stations where an operator can drain the bowl on a routine. Note the regulation range differs by drain: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
