The AirTAC GFR20006C3WTK AirTAC Filter Regulator NPT1/8 5um 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 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 GFR20006C3WTK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is the 200 size with a 1/8 in NPT port, fitted with a fine 5 um filter element (code W) for applications that need cleaner air than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round pressure gauge reading in bar. A reverse (check) valve is fitted, and the unit includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Feeding clean, regulated air to lab analysers, sample-conditioning panels and calibration benches, where the 5 um element protects sensitive pneumatic components from particulate and the bar gauge gives a clear local pressure readout.
Point-of-use air preparation on compact machining centres, bench presses and small pneumatic clamping fixtures, where a single body does both filtering and regulation and the check valve holds the downstream setting if supply pressure dips.
Dropping a filtered, regulated branch off a plant air header to feed sealing jaws, vacuum generators and actuator banks on packaging equipment, with the differential-pressure drain keeping condensate out of the machine without daily manual bleeding.
Start with the port and size: this unit is the 200 frame with a 1/8 in NPT port, the smallest step in the range - step up to GFR300/400/600 if your line needs more flow capacity. The 5 um element (code W) suits air tools, instruments and coating work that need finer filtration than the standard 40 um; if your air is already clean, the standard grade costs less and holds pressure drop lower. The differential-pressure drain is the fit-and-forget choice: it purges condensate automatically as air flows, with no timer or manual routine - choose a manual-drain version only for low-flow or intermittently used lines. The round gauge here reads in bar; square embedded gauges and MPa or psi scales are also available. Thread options are PT (standard), G (BSPP) or NPT, and a bracket is included for panel or wall mounting. Flow for this family is published as curves, not a single rating, so send us your flow and pressure requirements 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. 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 performance curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The W in the code specifies the fine 5 um filter element instead of the standard 40 um grade, for applications that need cleaner air downstream. The K specifies a fitted reverse (check) valve, which helps hold the regulated downstream pressure if the upstream supply drops. Both are standard catalogue options on the GFR family.
