The AirTAC GFR60025LC3WTK AirTAC Filter Regulator 1 in NPT, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" 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 GFR60025LC3WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, a low-pressure regulator type, a round gauge reading in bar, and a reverse/check valve fitted to hold downstream pressure. The 1 in NPT port suits high-flow main lines, and the aluminium alloy bowl reflects the heavy-duty 600 size construction. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is ordered with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G or NPT as options), bracket, and reverse valve. Flow figures for this series are published as curves rather than a single rating, so contact us and we will confirm the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 stamping or clamping line running large-bore cylinders off a 1 in main, this unit filters the supply to 5 um and holds a steady low regulated pressure so clamp force stays repeatable from cycle to cycle.
Packaging machines with many small valves fed from one header benefit from the 5 um element protecting pilot circuits, while the check valve holds the regulated pressure during brief upstream dips.
High-flow process lines driving air jets, doctor blades and web-cleaning nozzles use the 1 in port for volume, the 5 um grade to keep fine nozzles from clogging, and the bar gauge for operator-visible setpoints.
Start with the size and port: 600 is the largest G-series frame, with a 1 in port, so size the unit against the flow your line actually needs - we can check the published flow curves against your demand before you order. This unit carries the 5 um element (W); choose it where downstream valves, cylinders or instruments need finer air than the standard 40 um grade provides. Drain is differential-pressure, which self-bleeds with flow; if your line sees low or intermittent flow, ask about automatic or manual drain variants. The low-pressure regulator type is selected where the circuit works below the standard regulator band - the exact adjustment range for the low-pressure type is not published, so confirm it with us. The gauge here is the round external type with a bar scale; embedded square gauges and MPa or psi scales are the other catalogue options. Thread is NPT on this code (PT is the standard thread; G and NPT are order options), the mounting bracket is included, and the reverse/check valve is fitted to prevent downstream pressure decay. No stock or delivery commitment is made here - order by specification.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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. Send us your line pressure, regulated setpoint and expected air demand, and we will confirm the sizing from the datasheet curves on request before you order.
W is the 5 um filter element (instead of the standard 40 um), C3 is the external round gauge with a bar scale, T is the NPT thread (PT is the standard thread, with G and NPT as order options), and K means a reverse/check valve is fitted. The drain is the differential-pressure type and the mounting bracket is included.
