The AirTAC GFR600C20MJC1WT AirTAC Filter Regulator 3/4 NPT 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 GFR600C20MJC1WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 600-size unit is threaded 3/4 in NPT, carries a 5 um filter element (code W), drains by hand through its manual drain, and is fitted with an external round pressure gauge scaled in MPa. The size-600 bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 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, offered with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT thread. Flow is published as curves rather than a single rating, 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.

Feed clean, pressure-stable air to spray booths and paint guns, where the 5 um element catches fine particulate and the regulator holds a steady gun pressure through the shift.
Supply regulated air to pneumatic clamps and tool-change actuators on a machining centre, with the manual drain letting maintenance purge accumulated water at shift start.
Power the air cylinders that index and stop bottles on a filling line, with the regulator keeping cylinder action consistent as mains pressure wanders across the plant.
Choose the size step (200/300/400/600) and port to match the air demand of the line; this unit is the 600 frame with a 3/4 in NPT port. Drain type is a real choice: manual (this unit, which also widens the regulating range down to 0.05 MPa), automatic, or the default differential-pressure. Filter grade is 40 um standard or 5 um with the W code (this unit). Gauges are embedded square as standard or external round, scaled in MPa, psi or bar; thread is PT as standard with G and NPT as catalogue options, and a bracket can be included or omitted. Flow is published as curves, not a single rating, so send us your demand 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 series as curves rather than a single rated figure, so we do not quote a number here. Send us your line demand and operating pressure and we will confirm the flow from the datasheet for this 600-size, 3/4 in unit before you order.
This unit drains by hand: someone opens the drain to purge collected water from the bowl. On GFR units the manual-drain version also allows a wider regulating range, 0.05 to 0.9 MPa (7-130 psi), versus 0.15-0.9 MPa (20-130 psi) for the automatic and differential-pressure drains. If nobody is on site to drain it, ask us about the automatic option.
