The AirTAC GFR600C25ALC3WT 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 GFR600C25ALC3WT is a filter regulator: one body removes water and particulate down to 5 um and regulates downstream pressure in the same unit. This 600-size configuration is ported 1 in NPT, carries an automatic drain, the 5 um (W) filter element, a low-pressure type regulator and a round gauge with a bar scale. The bowl on size-600 units is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um elements, 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 figures against 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.

On a press shop air main, this 1 in filter regulator conditions the supply to clamp and hold-down actuators, stripping water and 5 um particulate before the valves while holding a reduced working pressure set on the bar gauge.
Feeding a packaging line's take-offs from a 1 in drop, the automatic drain clears condensate from the aluminium bowl without daily attention, keeping moisture out of the gate and diverter cylinders downstream.
In a panel supplying positioners and low-pressure actuators, the low-pressure type regulator suits circuits held at reduced pressure, with the 5 um element protecting sensitive pilot and control components.
Step up through the GFR sizes (200, 300, 400, 600) against the port and flow your line needs; this is the 600 size with a 1 in NPT port, the largest in the family. Choose the drain to match maintenance access: automatic (as here) discharges condensate without attention, manual suits attended installations, and differential-pressure is the default. Pick the 5 um element (W) where downstream equipment needs finer air than the 40 um standard. Gauge style and scale are decodable choices too: this unit has the round gauge with a bar scale, while the embedded square gauge with MPa, psi or bar scales is the other route. PT is the standard thread; G and NPT are catalogue options to order, and a bracket is included.
One honest routing note: AirTAC publishes flow as curves, not a single rated figure, and the exact adjustment range of the low-pressure type regulator is not published here. Ask us to confirm sizing and the regulator range 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 this family as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and demand and we will confirm the sizing from the datasheet curves on request before you order.
The automatic drain discharges collected condensate from the aluminium alloy bowl by itself, so the bowl does not need to be drained by hand at each shift. The unit operates from -5 to 70 C in non-freezing conditions; if the environment can freeze, plan protection accordingly.
