The AirTAC GFR600C20MLF1WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLF1WTK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built with a 3/4 in NPT port, a fine 5 um filter element (the 40 um standard element is the alternative), a manual drain on the bowl, and the low-pressure regulator type, so it suits lines that hold a lower regulated setpoint rather than full line pressure. The square pressure gauge is fitted with an MPa scale, a reverse/check valve is included, and the metal bowl (aluminium alloy at size 600) comes with a mounting bracket.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in to 1 in in PT (standard), G and NPT threads, drain choices, filter grades and gauge scales. We confirm flow and other datasheet figures on request, since flow is published as curves rather than a single rated number.

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 the clamp and fixture cylinders on a CNC machining cell, filtering the shop air to 5 um and holding a lower regulated setpoint for consistent clamping action.
Prepares air for carton-forming and sealing heads on a packaging line, where the fine element protects small valves and the low-pressure type matches the machine's regulated circuit.
Supplies filtered, regulated pilot air to automated process valves in a plant, with the 3/4 in NPT port, metal bowl and manual drain suiting a fixed installation with scheduled maintenance.
Work size and port against the air demand of the machine: size 600 with a 3/4 in NPT port is the large-flow end of the GFR range, so step down to 200/300/400 if the line is smaller. Choose the drain to match maintenance access: manual drain (this unit) needs someone to open it, the automatic type drains on its own, and the differential-pressure type is the default. Pick the 5 um element (code W, as here) for finer protection of downstream components, or 40 um for general duty. Gauge scale can be MPa, psi or bar; the embedded square gauge is standard and an external round gauge is optional. Thread is PT as standard with G and NPT as order options, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so ask us to confirm the flow against your application before ordering. The low-pressure regulator type is noted here; its exact adjustment range is not published in our sheet and we will confirm it on request.
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 family as curves rather than a single rated figure, so we do not quote a number here. Ask us and we will confirm the flow from the datasheet against your application before you order.
The manual drain (code M) means the accumulated water is released by hand, which suits installations visited during routine maintenance; automatic and differential-pressure drains are the alternatives in the range. This unit is the low-pressure regulator type; its exact adjustment range is not published in our sheet, so we will confirm it on request.
