The AirTAC GFR600C20MC1WTK 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 GFR600C20MC1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a 3/4 in NPT port, filters to 5 um (the fine grade, code W), and drains by hand through a manual drain, so an operator opens the drain when needed rather than relying on an automatic mechanism. Downstream pressure is set across 0.05-0.9 MPa (7-130 psi) with the standard regulator, a round external MPa gauge is fitted for direct reading, and a reverse/check valve (code K) holds the setting against backflow. The metal bowl on this size 600 unit is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans 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 as order options, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, and gauge or no-gauge variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Mounted at the 3/4 in air drop feeding a carton-forming and sealing line, it cleans the supply to 5 um and holds a steady regulated pressure to the line's valves and cylinders, with the manual drain bled at shift checks.
Installed ahead of a pneumatic press or clamping fixture, it filters incoming compressed air and lets the setter dial in the working pressure on the round MPa gauge, while the check valve helps hold the setting against backflow.
Fitted on the supply to air-driven conveyor actuators and boosters, it strips water and fine particles before they reach the components and keeps drive pressure within the 0.05-0.9 MPa setting range, with the aluminium bowl drained manually during maintenance rounds.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up or down (200/300/400/600) according to the pipe size and the flow your line needs - we can check the published flow curves against your demand before you order. This unit already carries the fine 5 um grade (W); the standard grade is 40 um if your application does not need fine filtration. The manual drain suits attended installations where an operator can bleed the bowl; choose automatic or differential-pressure drain codes for unattended duty. The fitted round gauge reads in MPa; square embedded gauges and psi or bar scales are the other catalogue choices. Thread here is NPT; PT is the AirTAC standard and G (BSPP) is also available to order. A bracket is included, and the check valve (K) is fitted on this code.
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 series as curves, not as a single rated figure, so we do not quote one number. Send us your line pressure, downstream pressure target and air demand, and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: the aluminium alloy bowl is emptied by hand, which suits attended installations. The same GFR600 family is also catalogued with automatic (A) and differential-pressure (blank) drains - those are separate order codes, and we can quote them on request.
