The AirTAC GFR600C20MLJF1WTK 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 GFR600C20MLJF1WTK is an AirTAC GFR600 filter regulator: water-and-particulate filtration and pressure regulation combined in one body. This 600-size unit has a 3/4 in NPT port, a 5 um filter element (code W) - one step finer than the standard 40 um grade - and a manual drain that you operate by hand to empty the bowl. On size 600 the bowl is aluminium alloy. The regulator is the low-pressure type, and this configuration includes an embedded square pressure gauge with MPa scale, a reverse (check) valve, and no mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge and thread options (PT standard; G and NPT to order), and bracket choices. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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 filtered, regulated air to the clamps, tool-changer and chip-ejection circuits of a CNC machining cell, with the 5 um element protecting downstream valves from fine particulate and the check valve holding the circuit if supply is interrupted.
Conditioning the air that drives diverters, pushers and sealing cylinders on a packaging conveyor line, where the manual drain lets an operator vent accumulated condensate during scheduled changeovers.
Supplying regulated low-pressure air to gating, capping and labelling heads on a bottling line, with the embedded square gauge giving a clear local pressure reference at the drop.
Choose the size by port and flow demand: sizes 200 through 600 step up from 1/8 in to 1 in ports, and this unit sits at the top of the range with a 3/4 in NPT port. Drain type is a real choice on GFR units: differential-pressure (default), automatic (A) or manual (M, as here) - manual suits installations where someone can regularly vent the bowl. Filter grade is 40 um standard or 5 um with code W; this unit carries the finer 5 um element. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT) are selected at ordering, as is the bracket. Flow is published as curves, not a single rating, so 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 rather than a single rated number, so we do not quote a figure here. Ask us and we will confirm the datasheet flow for this 600-size, 3/4 in NPT unit against your application before you order.
Drain type is a real choice on GFR units: differential-pressure (default), automatic (A) or manual (M). This model has the manual drain - the bowl is emptied by hand - which suits installations where an operator can vent it regularly. If the unit sits in an inaccessible spot, ask us about the automatic-drain version of the same size.
