The AirTAC GFR600C20MLJNWTK 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 GFR600C20MLJNWTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 configuration has 3/4 in NPT ports, a 5 um filter element (the W grade, finer than the 40 um standard), a manual drain, a low-pressure regulator, and a reverse/check valve fitted. No gauge is fitted and no mounting bracket is included. The metal bowl at size 600 is aluminium alloy. 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 ports from 1/8 to 1 in, and options for automatic, manual or differential-pressure draining, 40 um or 5 um filtration, gauge and scale choice, G (BSPP) or NPT thread in place of the PT standard, and bracket or no-bracket mounting. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm the datasheet for this exact model before you order.

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.

Conditioning air for the clamp-and-hold circuit of a forming or pressing cell where the regulator must sit at a low setpoint; the 5 um element keeps scale and pipe debris out of the clamping valves.
A point-of-use filter regulator ahead of the stopper and pusher cylinders on a packaging conveyor; the manual drain suits a line with scheduled end-of-shift maintenance rounds.
Supplying filtered, regulated air to a manifold of pneumatic process valves on a water-treatment or dosing skid; the fitted reverse/check valve helps hold the downstream setting if the supply dips.
Pick the size step (200 / 300 / 400 / 600) and port (1/8 to 1 in) against the air demand of your circuit - larger sizes carry larger ports and more flow, and we will confirm the published curve against your requirement on request. Drain type is a real choice: this unit is manual-drain (code M), so plan a routine drain check; automatic and differential-pressure drains are available on other variants. Filtration here is 5 um (code W) versus the 40 um standard - choose 5 um where downstream valves and instruments are sensitive. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us if your setpoint is critical. No gauge is fitted on this variant; gauge and scale options exist elsewhere in the family. Thread is NPT (code T); PT is the standard and G (BSPP) is an order option. This variant is supplied without a mounting bracket (code J).
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 G-series flow as performance curves, not as a single rated figure, so we do not quote a number here. Ask us for the datasheet and we will confirm the curve for this exact model against your application before you order.
Code M means you open the drain by hand to expel collected water, which suits positions covered by a maintenance round. If the unit sits where regular checks are impractical, choose the automatic-drain variant of the same GFR600 size; the differential-pressure drain is the family default.
