The AirTAC GFR20008C1WT 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 GFR20008C1WT is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This size 200 unit is configured with a 1/4 in NPT port, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds accumulated condensate automatically when the pressure differential across the element rises, and a round pressure gauge with MPa scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), the bowl is polycarbonate (PC), a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G(BSPP) or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, regulated air to the tool-clamp and pallet-clamp circuits of a CNC machining centre, where the 5 um element helps protect sensitive clamping valves from fine particulate and the gauge keeps set pressure visible at the machine.
Supplies conditioned air to the cylinders and air-jet nozzles on a carton packaging line, combining water removal and stable regulation in one body so diverters, sealers and case erectors see consistent pressure through each shift.
Conditions the air feeding benchtop lab automation - pick-and-place actuators and purge lines - where the 5 um grade and a clearly readable MPa gauge support repeatable, clean-air operation in a compact footprint.
Start with the port and size step: this unit is size 200 with a 1/4 in NPT port; larger sizes (300/400/600) carry larger ports and more flow capacity, so step up if your downstream demand is high. Choose the drain to suit the installation: differential-pressure drain (fitted here) discharges condensate automatically as the element loads, automatic drain suits unattended duty, and manual drain suits periodic service visits. Choose the filter grade: 40 um is the standard element, while the 5 um element fitted to this model (code W) suits finer downstream needs. Gauges are available embedded square or external round, with MPa, psi or bar scales - this unit carries an external round gauge in MPa. Threads come as PT (standard), G(BSPP) or NPT; this model is specified in NPT. A mounting bracket is included. Because flow for this series is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your port size, inlet pressure and downstream demand and we will confirm the flow and sizing from the datasheet on request before you order.
The W code in GFR20008C1WT specifies the optional 5 um filter element instead of the 40 um standard grade. Choose 5 um when downstream equipment such as precision valves, probes or instruments needs finer particulate removal; if your application does not require it, the 40 um standard element is the lower-restriction choice. Both grades are available across the GFR range.
