The AirTAC GFR200C08MLF3WTK AirTAC Filter Regulator NPT1/4 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 GFR200C08MLF3WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built on the GFR200 size with 1/4 in NPT ports, a 5 um filter element (the finer of the two published grades), a manual drain on the metal bowl, a low-pressure regulator type, an embedded square gauge scaled in bar, and a reverse/check valve fitted. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, and choices of drain type, filter grade, gauge scale, thread (PT standard, G and NPT to order) and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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 air preparation for a CNC machining centre: the 5 um element strips water and fine particulate before the machine's valves and cylinders, while the regulator holds supply pressure to clamps and the tool-changing circuit.
Air preparation for actuator circuits on a bottling or canning line: one body does the filtering and regulating ahead of the line's directional valves, with the manual drain emptied during scheduled changeovers.
Low-pressure circuits in a laboratory or pilot plant: this unit's low-pressure regulator type suits lines running at modest pressures, with the bar-scaled square gauge giving a readout in the units the process uses. We confirm the exact adjustment range from the datasheet on request.
Size is the first choice: GFR200 is the compact step of the range, and moving up to GFR300, 400 or 600 buys a larger port and more flow capacity - match the size to the air demand of the circuit rather than the pipe alone. Drain type is a real decision: this unit has a manual drain, which you empty by hand; automatic and differential-pressure drains are available on the same family if you cannot rely on scheduled manual draining. Filter grade is 40 um standard or 5 um (code W) as fitted here - choose 5 um where downstream equipment needs finer air. Gauge options are the embedded square gauge (MPa, psi or bar scale; this unit is bar) or an external round gauge. Thread is PT as standard with G and NPT as order options - this unit is NPT. Brackets are optional across the range and included on this unit. 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 PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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. Tell us your application and operating pressure and we will confirm the flow from the datasheet for this exact configuration before you order.
This unit has a manual drain: the bowl is emptied by hand on a schedule you control. If the installation is hard to reach or runs unattended, the same GFR family is available with an automatic or differential-pressure drain - both are decodable options, and we can quote the alternate code.
