The AirTAC GFR600C25MLC3WTK AirTAC 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 GFR600C25MLC3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body. This configuration is built around a 1 in NPT port, a 5 um filtration element (the finer of the two published grades), a manual drain on the bowl, and a low-pressure regulator type. A round gauge with a bar scale is fitted, a reverse/check valve is included, and the unit ships with its mounting bracket. At size 600 the bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 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 40 um or 5 um filtration, manual, automatic or differential-pressure drains, and gauge or no-gauge variants. Flow for this series is published as curves rather than a single rated figure, so ask us to 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.

Installed at a 1 in drop from a factory compressed-air ring main, it filters water and particles from the supply and holds a steady low-pressure feed to the downstream zone, with the manual drain cleared as part of routine rounds.
Feeding a workshop pneumatic press or clamping fixture, the unit conditions the incoming air to 5 um and lets the operator set and read the working pressure on the bar gauge before each cycle.
On a bottling or cartoning line, it supplies clean, regulated air to conveyor diverters and packaging cylinders, with the check valve holding the set circuit against backflow from downstream.
Size 600 with a 1 in port is the largest step in the GFR range, so start by matching the port and size against the air demand of the circuit; because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit pairs that port with the 5 um element (code W) rather than the 40 um standard, a manual drain you operate by hand rather than an automatic or differential-pressure drain, and a low-pressure regulator type - the exact regulation range for the low-pressure type is not published, so confirm it with us. The fitted gauge reads in bar; square embedded gauges and MPa or psi scales are the other published choices. NPT is the thread on this code, with PT standard and G available to order, and the 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 there is no one l/min or SCFM figure we can quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type; the exact regulation range for that type is not published in the material we hold, so confirm it with us before ordering if your set pressure is critical. The M marks a manual drain, so accumulated water in the aluminium bowl is released by hand rather than automatically. The 5 um element (W) is the finer published filtration grade, and the fitted round gauge reads in bar.
