The AirTAC GFR600C25ALJC3WT 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 GFR600C25ALJC3WT 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 built around a 1 in NPT port for high-capacity lines, a 5 um filter element (code W, tighter than the 40 um standard), an automatic drain that discharges collected condensate without manual attention, and a low-pressure (L) regulator type for circuits that sit below the standard adjustment band - the exact set range is not published, so confirm your set pressure with us. The fitted round gauge reads in bar, the metal bowl on size 600 is aluminium alloy, no mounting bracket is included, and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and optional brackets. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Drops a conditioned, regulated branch off the 1 in main feeding a filling and capping hall: the 5 um element protects downstream valves from fine particulate while the low-pressure regulator holds the gentle circuit pressure the bottle-grippers need, and the automatic drain keeps condensate off the floor without daily walk-rounds.
Sits at the head of the air supply to a conveyor section's pneumatic drives and stops, filtering line scale and water out of the air and regulating pressure down to the low setting the light-duty cylinders run at, with the bar gauge giving operators a visible setpoint at the panel.
Conditions and regulates the compressed air that strokes large diaphragm and butterfly valve actuators: the 1 in NPT port carries the volume the big actuators demand, the 5 um grade keeps the positioner air clean, and the aluminium-bowl automatic drain copes with condensate in an outdoor valve gallery.
Step up or down the size ladder (200 / 300 / 400 / 600) against the flow your line needs - larger sizes carry larger ports and more flow, and because flow is published as curves rather than a single rated figure, send us your demand and we will confirm the right size before you order. Where a bowl is fitted you choose the drain: differential-pressure (default), automatic (as on this unit, for unattended condensate discharge) or manual for hands-on control. Filtration is 40 um standard or 5 um with the W code, as selected here. Gauges come as the embedded square type or an external round gauge (this unit: round, bar scale) with MPa, psi or bar scales. Thread is PT as standard with G (BSPP) and NPT (as on this unit) as catalogue options to order, and brackets are optional - this configuration ships without one.
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 figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the flow curve and datasheet figures for this exact configuration on request before you order.
Both are decode choices in the model code: A is the automatic drain, which discharges condensate by itself instead of relying on the default differential-pressure drain or a manual drain, and W selects the 5 um element over the 40 um standard. If your application suits manual draining or standard 40 um filtration, ask us for the matching GFR600 variant in the same NPT1 port and low-pressure type.
