The AirTAC GFR600C25LF2WTK AirTAC Filter Regulator 1 in NPT 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 GFR series combines water and particulate filtration with pressure regulation in a single body, so one unit both cleans the air and holds a steady downstream pressure. This size 600 configuration is built around a 1 in NPT port and a 5 um filter element (the fine W grade, tighter than the standard 40 um). The regulator is the low-pressure type for applications that call for a lower set-point range, and the exact adjustment range is confirmed from the datasheet on request. It drains by differential pressure, so condensate is expelled automatically whenever the pressure differential across the element is high enough - no daily manual draining. The bowl on size 600 units is aluminium alloy, an embedded square gauge reading in psi is fitted, a reverse/check valve is fitted to hold downstream pressure, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures against 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.

Filtering and regulating the air fed to spray guns and atomising lines in a paint or powder-coating booth, where the 5 um element keeps oil mist and fine particles out of the finish and the low-pressure type holds a gentle, steady supply pressure.
Supplying clean, regulated air to the clamp and flap-fold cylinders on a packaging conveyor, with the check valve holding the downstream setting while upstream pressure fluctuates between machine cycles.
Feeding regulated air to leak-test fixtures and instrument panels on a test bench, where the 5 um grade protects sensitive gauges and the psi-scale square gauge lets operators read the set point directly.
Size and port set the capacity: this is the largest GFR frame, size 600 with a 1 in NPT port, matched to lines with high air demand. Because flow is published as curves and not a single rating, send us your required flow and we will confirm the sizing from the datasheet before you order. The 5 um W-grade element suits air that feeds sensitive valves, gauges or instruments; the standard 40 um grade is enough for general cylinders. Drain choice matters: this unit uses the differential-pressure drain (expels condensate automatically at high differential); automatic and manual drains are available on other codes. The embedded square gauge reads in psi; external round gauges and MPa or bar scales are options. Thread is NPT on this unit - PT is the standard thread and G/NPT are catalogue options to order. A mounting bracket is included.
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 number, so we do not quote a figure here. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
This code carries the L option, the low-pressure regulator variant, intended for applications set in a lower pressure band than the standard type. The exact adjustment range for the low-pressure type is not published in the material we hold, so we confirm it from the datasheet on request. Everything else is standard decode: 1 in NPT port, 5 um element, differential-pressure drain and a square psi gauge.
