The AirTAC GFR600C25ALC1WT 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 GFR600C25ALC1WT 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 for 1 in NPT ports, carries the 5 um (code W) filter element instead of the standard 40 um, drains condensate automatically, and is the low-pressure regulator type (L). An external round gauge scaled in MPa is fitted, and the mounting bracket is included. The metal bowl on this size-600 unit is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types, filter grades, gauge styles and scales, and low-pressure or standard regulation. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

Clamping frames that hold fabric during cutting and sewing run at modest regulated pressures. This low-pressure GFR with a 5 um element keeps lint and moisture out of the clamp cylinders while holding the setting the operators dial in.
Actuated fill and capping valves on a bottling line need clean, dry, steadily regulated air at low settings. The automatic drain clears condensate between shifts and the fitted MPa gauge lets technicians verify the setting at the machine.
Hold-down jets and gentle blow-off nozzles along a packaging conveyor run best at low pressure. The 5 um element protects the small orifices from particulate, and the 1 in NPT port serves the high-volume header feeding the station.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs; this unit sits at the top of the range with a 1 in NPT port. Choose the drain to suit access: automatic (as here) for unattended duty, manual for periodic service, or the differential-pressure default. Pick the 5 um element (code W) when downstream equipment needs finer filtration than the standard 40 um, and select the gauge style and scale (MPa, psi or bar) that your operators read. Thread is PT as standard with G and NPT as order options, and a bracket can be included or omitted.
Flow for this family is published as curves, not a single rating, so 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 family as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowed pressure drop, and we will confirm the flow figures from the datasheet for this exact unit before you order.
The automatic drain expels collected condensate on its own, which suits installations that run unattended or where manual draining is easy to forget. The 5 um element (code W) filters more finely than the standard 40 um element, protecting downstream valves, cylinders and gauges. Both are factory-set in this configuration, and the low-pressure regulator type is intended for applications regulated below the standard range - we confirm the exact range from the datasheet on request.
