The AirTAC GFR600C20LJF1WT AirTAC Filter Regulator NPT3/4 5um 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 GFR600C20LJF1WT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit is threaded NPT3/4, carries the 5 um filter element (code W) in place of the 40 um standard, drains by differential pressure, and has the embedded square gauge fitted with an MPa scale. It is the low-pressure regulator type, is supplied without a mounting bracket, and has no reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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 in to 1 in; the 600-size bowl is aluminium alloy, while smaller sizes use polycarbonate. Options across the family include differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, G or NPT threads and an optional bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Filtered, regulated air to clamp cylinders on a metal stamping cell, where the 5 um element protects seal surfaces from fine particulate and the MPa gauge keeps the set pressure visible at the cell.
Feeding diverters, sealers and pusher cylinders on a carton packaging line, with the differential-pressure drain clearing condensate as production runs and no daily bowl-draining routine.
Supplying pneumatic actuators on laboratory and analytical equipment, where the low-pressure regulator type and 5 um filtration suit sensitive downstream components.
Choose the size and port against the air your line consumes: 600 is the largest G-series size, here with a 3/4 in NPT thread. The 5 um element (W) suits downstream equipment that needs finer filtration than the 40 um standard, and the differential-pressure drain clears collected water as flow passes through, with no manual draining routine. The fitted square gauge reads in MPa; psi and bar scales are catalogue options, as are G-thread versions and an external round gauge. This code is the low-pressure regulator type and comes without a mounting bracket; bracketed versions are available in the family.
Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing from 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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and port requirements and we will confirm the sizing from the datasheet on request.
The W in the code selects the 5 um filter element instead of the 40 um standard. Choose it when downstream valves, cylinders or instruments need finer particulate removal; the standard 40 um grade is available in the same family if your application does not require it.
