The AirTAC GFR200C08C1WTK AirTAC Filter Regulator 1/4 NPT, 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 AirTAC GFR200C08C1WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in one compact body. This size 200 unit is threaded 1/4 in NPT, carries a 5 um filter element (code W) for finer filtration than the standard 40 um grade, drains condensate through its differential-pressure drain, and is fitted with an external round gauge scaled in MPa. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the built-in reverse/check valve (code K) holds the downstream setting if upstream pressure is lost. A mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, with a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge type and scale, PT, G or NPT threads, and an optional reverse/check valve. 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 sizing and 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 tool-changer and clamping circuit: the 5 um element protects directional valves from particulate and condensed water while the regulator holds a steady clamp pressure, and the check valve keeps clamps holding if supply pressure dips.
Feeding carton-sealing and case-erector cylinders on a packaging line: filtered, regulated air at the machine keeps cylinder action consistent through the shift, and the round MPa gauge lets line staff verify set points at a glance.
Supplying a pneumatic test bench in a lab or QA department: the 5 um grade and stable regulation suit instruments and test fixtures, and the check valve prevents fixture pressure drifting when the shop supply fluctuates.
Choose the size and port against the air your circuit actually uses: size 200 with a 1/4 in NPT port suits compact point-of-use drops, while sizes 300, 400 and 600 step up in port and flow capacity - we can confirm the flow curve against your demand before you order. This unit pairs a 5 um element (code W) with a differential-pressure drain; if your air is relatively clean the standard 40 um grade may suffice, and if the unit sits where manual intervention is impractical, an automatic or manual drain variant may suit better. The fitted round gauge reads in MPa; psi and bar scales are order options, and an embedded square gauge is the standard alternative. Threads come as PT (the standard), G (BSPP) or NPT - this configuration is NPT - and the mounting bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements and we will confirm this is the right size 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 GFR flow as curves rather than a single rated figure, so we do not quote a rated l/min or SCFM number. Send us your required flow and upstream pressure and we will confirm against the datasheet curve that this size 200, 1/4 in NPT unit is correctly sized - on request, before you order.
W selects the 5 um filter element instead of the standard 40 um grade, giving finer protection for sensitive valves and instruments. K means a reverse/check valve is fitted, so the downstream setting is held if upstream pressure is lost. Both choices are decodable directly from the model code.
