The AirTAC GFR600C20ALJNWTK 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 GFR600C20ALJNWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit has a 3/4 in NPT port, a 5 um filter element (code W), an automatic drain on the aluminium alloy bowl, and the low-pressure regulator type. No pressure gauge is fitted and no mounting bracket is supplied; a reverse (check) valve is built in.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with 1/8 in to 1 in ports, differential-pressure, automatic or manual drains, 40 um standard or 5 um elements, gauge options and PT, G or NPT threads. AirTAC publishes flow for this family as curves rather than a single rated figure, so ask us to confirm the datasheet 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.

Filtering and regulating air ahead of bag-sealing and carton-closing cylinders on a packaging machine that runs at a low regulated pressure, with the automatic drain discharging collected condensate without daily manual bleeding.
Feeding filtered, low-pressure regulated air to the diverting and stopper cylinders on a parcel-sorting conveyor, where the 5 um element helps protect directional valves from dirt and the built-in check valve blocks reverse flow.
Supplying clean, low-pressure regulated air to sample-handling actuators and purge lines on analytical instruments, with the 5 um element and the aluminium alloy bowl of this 600-size unit in a low set-point duty.
Within the GFR line the real choices are size and port (200/300/400/600, 1/8 in to 1 in) matched to the air demand of the circuit; drain type (differential-pressure standard, automatic or manual); filter grade (40 um standard or 5 um, as fitted here); gauge and scale; thread (PT standard, G or NPT to order); and bracket. This unit is the low-pressure regulator type with automatic drain, 5 um element, NPT thread, no gauge and no bracket. Flow is published as curves, not a single rating, so send us your flow and pressure conditions and we will confirm 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 the GFR family as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your required flow and working pressure and we will confirm the figures from the datasheet for this GFR600 3/4 in unit before you order.
This configuration is coded N for gauge, so no pressure gauge is fitted; gauges are an option on GFR units if you want a visual set-point reference. It is also the low-pressure (L) regulator type, intended for lower set-point duties. The exact adjustment range for this variant is not published in the catalogue, so we confirm it on request.
