The AirTAC GFR20008C3WTK AirTAC Filter Regulator NPT1/4 5 um 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 PT1/4" 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 GFR20008C3WTK is a size-200 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a 1/4 in NPT port, a fine 5 um filter element (the W grade, against the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically as pressure drops across the element, an external round gauge reading in bar, a built-in reverse/check valve that holds downstream pressure when the supply is lost, and a mounting bracket. The polycarbonate bowl is rated to a maximum inlet pressure of 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi), and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and thread options in PT, G (BSPP) and NPT. Drain, filter grade, gauge style and scale, regulator type and check-valve options can be selected per code. Published flow data appears as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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 0.15 - 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 clamps and small press cylinders on an assembly fixture: the 5 um element keeps fine debris out of valve seats, the regulator holds a steady setting, and the check valve holds the clamp circuit if shop air drops.
Point-of-use conditioning for diverters, gates and stop cylinders on a packaging conveyor, where the differential-pressure drain sheds condensate during normal cycling and the bar gauge gives operators a visible line-pressure reference.
Supplying air to pilot-operated control components and positioners on a process skid, where the fine 5 um grade and a locked regulator setting protect sensitive pilot circuits from particles and pressure drift.
Start with the port step: size 200 with a 1/4 in NPT port suits lighter-duty lines, while sizes 300, 400 and 600 move up in port and capacity - match the size to the flow your circuit needs rather than to the pipe alone. Choose the drain: differential-pressure (this unit) drains only when flow-induced pressure drop is present, automatic drains continuously, and manual requires periodic bleeding; pick automatic or manual if your line runs at steady low flow. Choose the element: 40 um for general protection, 5 um (code W, fitted here) for finer downstream components. Then set the gauge style and scale (embedded square or external round; MPa, psi or bar) and the thread family - PT is the standard, with G and NPT as order options. 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. 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 we do not quote a figure here. Send us your application - working pressure, downstream consumption and line length - and we will confirm the datasheet flow figures for this 1/4 in NPT size-200 unit on request before you order.
In the GFR code the W position selects the fine 5 um filter element instead of the 40 um standard, and K fits a reverse/check valve that holds downstream pressure when the upstream supply is lost. Both are decodable order options: choose 40 um for general-purpose protection and omit K if you do not need pressure retention.
