The AirTAC GFR600C25C1WT 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 GFR600C25C1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady at your setpoint, in one body. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (code W, against the standard 40 um), a differential-pressure drain on the bowl, and a round pressure gauge reading in MPa. The bowl on size 600 is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for drain type, 40 or 5 um filtration, gauge style and scale, G/NPT thread, and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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.

Clean, regulated air at the supply point for a paint line: the 5 um element strips water and particulate before atomising equipment, while the regulator holds a steady setpoint so spray and conveying actuators behave consistently through the shift.
On a machining centre with air-actuated fixtures and tool-change cylinders, this unit filters the shop air and keeps clamp pressure stable, so workholding force does not wander as the main line pressure fluctuates.
A beverage plant's conveyor stops, pushers and gate cylinders run off a 1 in branch header; this filter regulator cleans the supply and pins the pressure so bottle handling stays repeatable from start-up to shutdown.
Size and port are the first choice: step through 200, 300, 400 and 600 as your flow demand and line size grow; this unit is size 600 with a 1 in NPT port. The 5 um element (W) gives finer filtration than the standard 40 um - choose it where downstream valves, cylinders or instruments need cleaner air. Drain on this code is differential-pressure; automatic (A) and manual (M) versions exist. The round gauge fitted reads in MPa; an embedded square gauge is the standard fitting, and psi or bar scales are alternatives. Thread is NPT on this code; PT is the AirTAC standard and G (BSPP) is also available to order. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, 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 GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Send us your line size, downstream demand and working pressure, and we will confirm the flow and the full datasheet figures for this exact model on request.
The W code in GFR600C25C1WT fits a 5 um element, which removes finer particulate than the 40 um standard - the right choice ahead of precision valves, instruments or finishing equipment. For general plant air, the same unit can be ordered without the W code to get the standard 40 um element.
