The AirTAC GFR20006MC1WTK AirTAC Filter Regulator 1/8 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/8" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR200 series combines water and particulate filtration with pressure regulation in a single compact body, so one 1/8 in ported unit both cleans the compressed air and sets a stable downstream pressure. This specific configuration, GFR20006MC1WTK, is built with a 5 um filter element for finer dirt and water carryover removal than the standard 40 um grade, a manual drain for the PC (polycarbonate) bowl that you empty by hand on your own schedule, a round pressure gauge with an MPa scale for direct setpoint reading, and a built-in reverse (check) valve that holds the downstream circuit when upstream supply is lost. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), the unit accepts a maximum inlet pressure of 1.0 MPa (145 psi), and it operates from -5 to 70 C in non-freezing conditions. A mounting bracket is included.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and with options including G (BSPP) or NPT thread, automatic or manual or differential-pressure drains, 40 um or 5 um filtration, and square or round gauges in MPa, psi or bar scales. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and flow-curve 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 0.05 - 0.9 MPa (7 - 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 conditioning for the air feeding a CNC machine tool's tool-changer and clamping cylinders: the 5 um element protects fine control valves from particles and water carryover, while the regulator sets the clamping circuit pressure and the check valve holds the setting if shop air drops.
Conditioning the air supply to a cartoning or bagging conveyor's pneumatic diverters, seal bars and reject pushers, where the manual drain suits a line that is bled down at shift end and the round MPa gauge lets the line technician verify set pressure at a glance.
Clean, regulated air for a lab automation bench running pipetting heads and small gripper actuators, where the compact 1/8 in ported size fits tight under-bench space, the 5 um grade guards sensitive mini valves, and the included bracket mounts the unit to the frame.
Start with the port and size step: this unit is a size 200 with a 1/8 in port, the smallest step in the GFR range, so match it against the air consumption of the machine or circuit it feeds and step up to GFR300/400/600 if the line needs a larger port. Next, choose the drain: this version has a manual drain, which suits attended installations where an operator can bleed the bowl; pick the automatic drain variant for unattended or hard-to-reach positions. The 5 um element (code W) is the right choice when downstream valves, cylinders or instruments are sensitive to fine particles; the standard grade is 40 um. The round MPa gauge fitted here gives a clear local pressure readout, and psi or bar scales are available as alternatives. Thread is NPT on this unit; PT is the standard thread and G (BSPP) is also an order option. A mounting bracket is included. One honest note on sizing: flow for this series is published as curves, not a single rating, so send us your application details and we will confirm the sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so there is no honest one-figure rating we can quote. Send us your application details and we will confirm the flow-curve and datasheet figures for this exact 1/8 in, 5 um configuration on request before you order.
The M in the code specifies a manual drain: condensate collected in the PC bowl is released by hand rather than automatically. Choose manual drain where the unit is accessible and the installation is checked regularly; choose the automatic-drain variant of the same GFR200 series where the unit is mounted in an awkward position or the line runs unattended. Remember the unit is rated for -5 to 70 C, non-freezing.
