The AirTAC GFR600C25ALJC3T AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR600C25ALJC3T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit carries a 1 in NPT port, an automatic drain that discharges condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, and a round pressure gauge reading in bar. It is the low-pressure type of the GFR family, and no mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow 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.

Mounted at the drop feeding spray guns and air-assisted applicators, this unit strips water and swarf from the supply and holds the reduced pressure the applicator station calls for, with the automatic drain keeping the aluminium bowl clear through long shifts.
Installed ahead of the valve manifold that drives filler clamp and capper-head cylinders, it cleans the plant air and sets a stable reduced pressure for the machine section, while the bar-reading gauge gives operators a local reference at the frame.
Fitted at the feed to pusher and gate cylinders on a packaging conveyor, it removes condensate and particulate before they reach the seals and sets the working pressure the station needs, with the 1 in NPT port matching the main drop on a high-demand line.
Size and port set the capacity: this is the largest GFR size (600) with a 1 in NPT port, the step to take when your line's air demand points to the top of the range - verify against the published flow curves for your conditions. The automatic drain suits duty where nobody is emptying bowls; manual and differential-pressure drains are available on other codes if you prefer operator-controlled or pressure-differential draining. Filtration here is the 40 um standard element; a 5 um element (code W) is the choice for finer protection of sensitive downstream components. The round gauge reads in bar; embedded square gauges with MPa, psi or bar scales are also offered across the series. PT is the standard thread and G or NPT are order options - this unit carries NPT. No mounting bracket is included with this code. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application 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 this series as curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, downstream pressure and air demand and we will confirm the sizing from the datasheet curves before you order.
The automatic drain discharges collected condensate from the bowl without anyone having to open it, which suits unattended or hard-to-reach positions. The GFR series is also available with manual or differential-pressure drains on other codes if your maintenance routine prefers those.
