The AirTAC GFR600C20MLF2WTK AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20MLF2WTK is an AirTAC GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 configuration carries a 3/4 in NPT port, a fine 5 um filter element (the W grade, against the 40 um standard), a manual drain for emptying the aluminium alloy bowl by hand, and a low-pressure regulator type. It ships as coded with the embedded square gauge on a psi scale, a reverse/check valve fitted to hold downstream pressure, and a mounting bracket included. 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 from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT/G/NPT threads, drain types, filter grades, gauge styles and scales. Flow for this series is published as curves rather than a single rated figure, so ask us to 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.

Filtering and regulating the air feeding clamp and hold-down cylinders on a machining fixture, where the fine 5 um element protects directional valves and the check valve helps hold the clamped state.
Conditioning the supply to carton-sealing and case-erector cylinders on a packaging line, with the manual drain emptied during scheduled changeover and the psi gauge giving operators a local setpoint readout.
Supplying filtered, regulated air to lab analysers and test benches fed from a shop-air header, where the low-pressure regulator type and 5 um filtration suit sensitive downstream equipment.
Start with the port step: size 600 with a 3/4 in port sits at the top of the G-series range, so match it to the line size and the air demand of the circuit it feeds. Choose the drain to suit access: manual (as coded here) means an operator drains the bowl by hand, while the family also offers automatic and differential-pressure drains for unattended duty. Choose the filter grade: 40 um is the standard element and 5 um (W, as coded here) suits finer protection downstream. Pick the gauge scale (MPa, psi or bar) and style, the thread family (PT is the standard; G and NPT are order options), and whether a bracket is wanted. Note the low-pressure regulator type in this code: its exact adjustment range is not published in the material we hold, so confirm it with us. Because flow is published as curves rather than a single rating, 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 series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your line pressure and air demand and we will confirm the flow figures from the datasheet for this exact model on request.
The M in this code specifies a manual drain: the accumulated water in the aluminium alloy bowl is emptied by hand, which suits stations visited during routine checks. Within the same GFR family you can order automatic or differential-pressure drains instead if the unit will sit unattended.
