The AirTAC AirTAC GFR600C25ALC1WTK Filter Regulator NPT 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 GFR600C25ALC1WTK is a size-600 filter regulator: water and particulate removal plus pressure regulation in a single body, with a 1 in NPT port for high-flow main air lines. This configuration carries the W 5 um filter element for finer air cleaning than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, and the L low-pressure regulator type for circuits held below standard line pressure. The metal bowl (aluminium alloy at size 600) suits environments where a polycarbonate bowl is not preferred, and the fitted reverse/check valve holds downstream pressure if the upstream supply is interrupted. An external round gauge on the MPa scale is fitted so set pressure is visible at the unit.
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 drain types, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

Feeds a dedicated low-pressure branch serving clamping and seating fixtures, with the 5 um element protecting valves from fine particulate and the automatic drain keeping condensate off the circuit.
Provides filtered, regulated air to pick-and-place and test-rig actuators, where the 5 um grade, visible MPa gauge and check valve give clean, monitored, hold-on-loss supply to sensitive instruments.
Sits at the 1 in main drop feeding a cartoning and wrapping line, filtering water and particles from the plant air and holding a stable low regulated pressure to the downstream FRL-fed machines.
Start with the port step: size 600 with a 1 in port serves the largest branch lines in the GFR range, so match it to your line size and required air delivery before stepping down. Choose the drain to suit access: automatic (this unit) drains itself, manual suits supervised stations, and differential-pressure is the default compromise. Pick the 5 um W element when downstream equipment needs finer air than the standard 40 um grade. Select the gauge scale (MPa, psi or bar) your technicians read, and order PT, G or NPT thread to match your piping standard - NPT on this unit. A mounting bracket is included with this configuration.
Flow for GFR units is published as curves, not a single rated figure, so ask us to confirm sizing against your flow demand 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, regulated pressure and air demand, and we will confirm the flow and sizing from the datasheet on request.
The A code fits an automatic drain, so collected condensate is expelled without anyone opening the bowl - useful for elevated, enclosed or infrequently visited installations. If your station is checked daily, the manual drain option costs less; the differential-pressure drain is the standard default. This unit also carries the 5 um W element, the low-pressure regulator type, a round MPa gauge and a fitted reverse/check valve.
