The AirTAC GFR600C25C3WT AirTAC Filter Regulator NPT1 (1 in) 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 GFR600C25C3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded NPT1 (1 in), carries the 5 um filter element (code W) instead of the 40 um standard element, drains condensate by differential pressure, and is fitted with a round pressure gauge reading in bar. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Because this is the 600 size, the bowl is aluminium alloy, and the unit operates from -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 PT (standard), G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge options and scales, and low-pressure variants. Flow figures for this series 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 the 1 in header feeding a press shop, the unit strips water and chips from the plant air supply and holds a steady regulated pressure to the valve stands downstream.
On a bottling or cartoning line, the filter regulator conditions the air feeding cylinder-driven conveyor stops and pushers, with the 5 um element guarding sensitive directional valves.
For a machine builder wiring pneumatic panels on CNC or assembly equipment, the single-body filter regulator simplifies the FRL drop, and the bar-scale round gauge gives operators a local pressure readout.
Size and port are the first choice: the 600 frame steps up to 1 in ports for higher-flow mains, while 200/300/400 cover smaller drops - match the frame to the flow your line needs. Then set the drain (differential-pressure as here, automatic, or manual), the filter grade (40 um standard or 5 um as on this unit for finer protection), the gauge type and scale (MPa, psi or bar), the thread (PT standard; G and NPT are order options), and the bracket. Flow for this series is published as curves, not a single rating, so please ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a l/min or SCFM number. Send us your line size and demand and we will confirm the datasheet flow figures for this 1 in NPT unit on request.
The 40 um element is the standard grade for general plant air; the 5 um element fitted to this model gives finer particulate removal for downstream valves, cylinders and instruments that tolerate less contamination. Both grades are available across the GFR range, and the drain on this unit is differential-pressure either way.
