The AirTAC GFR600C25F3WT AirTAC Filter Regulator NPT1 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 GFR600C25F3WT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (the W grade, finer than the standard 40 um), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), an embedded square gauge with bar scale shows the set pressure at a glance, and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. At size 600 the bowl is aluminium alloy, 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, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filter elements, square or external round gauges with MPa, psi or bar scales, and PT (standard), G or NPT threads to order. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air feeding tool clamps, pallet changers and air blast on a machining centre - the 1 in port serves a whole cell from one drop, and the 5 um element protects precision clamping valves.
Steady regulated pressure to cylinders and grippers on a high-speed packaging or cartoning line, where pressure swings cause inconsistent stroke timing and jammed product.
Clean, moisture-reduced air at a fixed pressure feeding spray guns and air-driven agitators in a finishing booth, with the 5 um element catching particles that would ruin a finish.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow your line needs - this unit sits at the top of the range with a 1 in NPT port for the highest-flow installations. Choose the drain to suit maintenance habits: differential-pressure (as fitted here) drains on demand, automatic drains on a cycle, manual only when someone opens it. Pick the element grade: 40 um standard for general plant air, 5 um (this unit) where downstream valves and instruments need finer protection. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are decodable choices; a bracket is included for panel or wall mounting. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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 curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and the flow your application needs, and we will confirm against the datasheet whether this size 600, 1 in NPT unit is correctly sized before you order.
The W code in the model sets the finer 5 um element, which suits downstream valves, instruments and spray equipment; the standard grade is 40 um if you ever order a variant. This unit uses a differential-pressure drain: condensate collected in the aluminium alloy bowl is discharged automatically when the pressure differential across the element rises, so no manual draining routine is required.
