The AirTAC GFR20008C3WT 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 GFR20008C3WT is a size-200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration is built around a 1/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises. An external round gauge scaled in bar is fitted so the set pressure is visible at a glance, and a mounting bracket is included for panel or wall fixing. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the unit operates from -5 to 70 C in non-freezing conditions. The polycarbonate bowl suits this size range.
This is a genuine AirTAC part. The GFR filter-regulator family is published in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauge styles and 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.

A filtered, regulated air drop feeding the tool-change and clamping circuits on a CNC machining centre, where the 5 um element helps keep fine pilot valves clean and the bar gauge lets setters verify set pressure.
Regulating the air to sealing bars and vacuum generators on a carton or blister packaging line, with the differential-pressure drain handling condensate through shift after shift without operator attention.
Supplying steady pressure to divertors, stoppers and lifters on a sortation conveyor, where the included bracket mounts the unit at the control cabinet and the round bar gauge gives a visible setpoint check.
Choose the size and port step by the air your circuit actually consumes: the GFR200 with its 1/4 in port is the smallest step in the family, and larger sizes carry larger ports and more flow. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering. On this code the 5 um element (W) is selected instead of the standard 40 um - pick 5 um where downstream valves or instruments need finer air, 40 um for general plant air. The differential-pressure drain is the default and needs no operator attention; a manual (M) or automatic (A) drain can be ordered instead. The fitted round gauge reads in bar; embedded square gauges and MPa, psi or bar scales are the other catalogue choices. Thread is NPT on this unit, with PT (standard) and G available to order, and the bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulation range is 0.15-0.9 MPa (20-130 psi).
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 this series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request before you order.
The W in the code GFR20008C3WT selects the 5 um filter grade; the catalogue standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer air, and 40 um for general plant air. Both grades are orderable in this family.
