The AirTAC GFR200C08F2WTK AirTAC Filter Regulator NPT1/4 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 GFR200C08F2WTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 200 unit carries a 1/4 in NPT port, a 5 um filter element for finer particle capture than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining. The fitted square gauge reads in psi, and the built-in check valve lets downstream air bypass the unit on reverse flow, which protects the element and bowl in circuits that vent or cycle.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and PT, G or NPT threads, plus manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge choices. Flow figures for this model are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers against your application before you order.

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.

Feeds filtered, regulated air to the tool-changer and clamping circuits of a CNC machining centre, where the 5 um element keeps fine particles out of pilot valves and the psi gauge lets setters verify setpoint at a glance.
Mounted at the drop ahead of a packaging conveyor's pneumatic diverters and sealing cylinders, holding a steady working pressure through shift-long cycling while the differential-pressure drain handles condensate without operator attention.
Conditions the supply to a lab analyser or purge cabinet, where the 5 um grade protects sensitive internal components and the check valve prevents backflow through the unit when the instrument vents its own circuit.
Size 200 with a 1/4 in NPT port is the entry step of the GFR range; if your line draws more air than the size 200 flow curve supports, step up to size 300 or 400 rather than oversizing the regulator setting. The 5 um element (code W) suits points of use that see fine contamination - instrument air, painting, sensitive valves - while the standard 40 um grade is enough for general shop-air protection; the element choice is yours to make per position. Drain is differential-pressure here, which suits unattended duty; choose automatic for continuous condensate loads or manual where someone walks the line daily. The square gauge is psi-scaled; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread and G or NPT are catalogue options - this unit is the NPT version. A mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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, not as a single rated number, so we do not quote a figure here. Send us your application - port size, working pressure and the air demand of the equipment - and we will confirm the flow data from the datasheet and check the sizing before you order.
The W in the code selects the 5 um filter grade; the blank-code default is 40 um. The 5 um element captures finer particles for points of use such as instruments, painting or sensitive pilot valves, while 40 um remains the right choice for general machine-air protection. Both grades are catalogue options across the GFR range, so you can match the grade to each position.
