The AirTAC GFR600C20MJC3TK 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 GFR600C20MJC3TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is built around a 3/4 in NPT port, a 40 um standard filter element, and a manual drain, so condensate is released when an operator opens the drain rather than automatically. Outlet pressure is set with the standard regulator over a 0.05-0.9 MPa (7-130 psi) range, read on the fitted round gauge with a bar scale. A reverse/check valve is fitted, the aluminium alloy bowl suits the size 600 body, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with automatic, manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads, and with or without a bracket. Published flow data appears as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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.

Installed at the drop feeding a machining centre's pneumatic clamps and tool-change actuators, this unit strips water and chips-laden particulate from the shop air and holds a steady regulated pressure so clamping force stays repeatable across shifts.
Mounted on the air drop serving a packaging conveyor's stopper cylinders and diverters, the 3/4 in port carries the line's air volume while the 40 um element and regulation keep dirt and pressure swings out of the divert mechanics.
Fitted on the utility-air header feeding a lab's pneumatic valves and sample-handling actuators, the unit gives technicians a bar-scale gauge to set working pressure and a manual drain for scheduled condensate removal at the start of each day.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest step in the family, chosen when the line and connected cylinders or valves demand the higher flow capacity of the 600 frame. Match the thread to your piping: PT is the standard, while G (BSPP) and NPT are catalogue options ordered by suffix - this unit carries the T (NPT) option. Choose the drain for the duty: manual suits attended installations with periodic blowdown, automatic suits unattended duty, and differential-pressure drain is the default. Filter grade is 40 um as standard for general plant air; specify the 5 um W element where downstream equipment needs finer filtration. Gauge is a fitted round gauge on a bar scale here; square embedded gauges and MPa or psi scales are alternatives. Brackets are optional - this configuration ships without one.
Because AirTAC publishes flow only as curves and not as a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm sizing against the datasheet curves 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 flow number. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing against the datasheet curves on request before you order.
T is the thread option: this unit has a 3/4 in NPT port instead of the PT standard (G/BSPP is also a catalogue option). K means a reverse/check valve is fitted, holding upstream conditions if supply pressure is lost. The M in the code is the manual drain, and J means no mounting bracket is included.
