The AirTAC GFR600C25F1WT 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 GFR600C25F1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 600-size unit is threaded 1 in NPT, carries a 5 um filter element (the finer of the two catalogue grades), drains condensate by differential pressure, and reads outlet pressure on an embedded square gauge scaled in MPa. The 600-size bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the unit operates from -5 to 70 C in non-freezing compressed air.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and each size can be ordered with a 40 um or 5 um element, differential-pressure, automatic or manual drain, an embedded square or external round gauge (MPa, psi or bar scales), G, NPT or PT threads, and with or without a mounting bracket. Flow for this series is published as curves rather than a single rating, 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 0.15 - 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.

Dropping from a compressor-room header into a 1 in branch feeding impact wrenches and air hoists on an automotive assembly floor, holding a steady regulated supply to the tools.
Conditioning the air that drives gripper and pusher cylinders on a bottling conveyor, with the 5 um element keeping scale and pipe debris out of the directional valves.
Feeding clean, regulated air to the solenoid valves and pneumatic clamps of a CNC machining cell, where a drift in supply pressure would show up as inconsistent clamping.
Every position in GFR600C25F1WT is a choice you can make differently elsewhere in the line. Size 600 with a 1 in port sits at the top of the range; step down to the 300 or 400 sizes when the line is smaller. Drain: differential-pressure (this unit) bleeds condensate as the bowl fills, automatic (A) drains without a pressure drop, and manual (M) needs a periodic twist of the drain screw. Filter grade: 40 um is standard, while 5 um (code W, this unit) suits finer downstream valves and instruments. Gauge: the embedded square gauge is standard in MPa; external round gauges in MPa, psi or bar are optional. Threads come as PT (standard), G (BSPP) or NPT, and a mounting bracket is included on this unit.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated figure, so we cannot quote a number here. Send us your flow and pressure requirements and we will confirm the right size from the datasheet 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 series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line size, inlet pressure and required downstream flow, and we will confirm the figures from the datasheet for this 1 in NPT unit before you order.
The W code orders the 5 um element in place of the 40 um standard, and that is what this unit carries. Choose 5 um when downstream solenoid valves or instruments need finer filtration; the 40 um element remains the standard fitment for general plant air in the same GFR600 body.
