The AirTAC GFR600C20MLNWTK 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 GFR600C20MLNWTK combines water and particulate filtration with pressure regulation in a single AirTAC GFR600 body, sized for a 3/4 in NPT port. This configuration carries the 5 um filter element (code W) for finer cleaning than the 40 um standard, a manual drain on the bowl, the low-pressure regulator type, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. No gauge is fitted (code N), so add a separate gauge if you need to read the regulated line. The size 600 bowl is aluminium alloy, and the unit includes a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, gauge and thread options, and an optional low-pressure regulator type. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for 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.

Feeding clamps and light press cylinders on a fabrication cell, where the 5 um element protects valve spools and the check valve holds the circuit while the main supply is vented or switched off.
Supplying air to diverters, stoppers and pusher cylinders on a packaging or bottling conveyor, with the low-pressure regulator type suited to lines that run below standard plant pressure.
Conditioning supply air for bench-top test rigs and laboratory apparatus that need clean, finely filtered air at a stable reduced pressure, with manual draining during scheduled checks.
Step up or down the size ladder (200 / 300 / 400 / 600) against the flow your line needs - 600 is the largest, with the 3/4 in port decoded here. Choose the drain to match maintenance practice: manual (this unit) means someone opens the drain at intervals, automatic drains unaided, and the differential-pressure default drains on a pressure drop. Pick 5 um (this unit) when downstream equipment needs finer air than the 40 um standard, and note that no gauge is fitted, so plan external gauging if operators must read set pressure. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. A bracket is included.
Because published flow data comes as curves rather than one rated number, send us your application details and we will confirm the sizing against the datasheet before you order.
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 this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
The N in the code means no gauge is fitted, so add a separate gauge if operators need to read the regulated pressure. The K code means a reverse/check valve is built in, which holds downstream pressure if the upstream supply is interrupted.
