The AirTAC GFR600C20MJF1WTK 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 AirTAC GFR600C20MJF1WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is the largest in the G-series range, with a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), a manual drain on the aluminium alloy bowl, an embedded square gauge reading in MPa, and a reverse (check) valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C non-freezing, and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT to order, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge or no-gauge variants. 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.

Point-of-use water removal and steady regulated pressure for CNC machining centres and their pneumatic clamps on a 3/4 in drop leg.
Clean, regulated air for the cylinders and grippers on a carton-forming or bottling conveyor, with the 5 um element protecting downstream valves.
Filtered, regulated air at the booth drop ahead of spray guns and air tools, where the manual drain lets an operator bleed the bowl each shift.
The real choices in this family are all decodable from the code. Step through sizes 200/300/400/600 to match the port and flow path your line needs - this unit is the 600 size with a 3/4 in NPT thread (PT is the catalogue standard; G and NPT are order options). Drains come as differential-pressure (default), automatic or manual - this one is manual, so the bowl is emptied by hand. Filter grade is 40 um standard or 5 um with the W code - this one carries the 5 um element. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit has the square MPa gauge. Brackets are optional - this configuration is supplied without a mounting bracket. Flow is published as curves, not a single rating, so send us your application details 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 G-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet curve for this exact configuration on request.
This unit carries the M code, so the bowl is drained by hand - a good fit where an operator is already at the machine each shift. The GFR family is also published with differential-pressure (default) and automatic drains; if you would rather not drain by hand, ask us for the equivalent automatic-drain model.
