The AirTAC GFR20008LC1WT 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 GFR200 series is a 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 1/4 in NPT port, fitted with the fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, the low-pressure regulator type for applications that run below standard regulating ranges, and an external round pressure gauge reading in MPa. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing); the polycarbonate bowl suits the 200 size.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and is ordered with a choice of drain type, filter grade (40 um standard or 5 um), gauge style and scale, thread (PT standard, G or NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 bench-mounted pneumatic press running at reduced line pressure needs clean, steady air at its control valve. This unit's 5 um element protects the valve and cylinder from particulate and condensed water, while the low-pressure regulator type and MPa gauge let the operator set and read the reduced working pressure directly at the station.
A lab bench distributing compressed air to small actuators and test fixtures benefits from fine filtration and gentle regulation. The 5 um element keeps moisture and debris out of sensitive instruments, the differential-pressure drain sheds condensate without daily manual attention, and the round MPa gauge gives a clear local pressure readout.
On a carton-forming machine, vacuum and air-jet circuits often run at deliberately low pressures to avoid damaging lightweight product. This filter regulator conditions the supply with 5 um filtration, regulates it down with the low-pressure type, and its 1/4 in NPT port drops straight into the machine's existing pipework.
Start with the port step: the 200 size carries a 1/4 in port, and larger sizes (300/400/600) step up in port and flow capacity - match the size to the air demand of the circuit rather than upsizing blindly. Choose the filter grade for the task downstream: 40 um is the standard element for general protection, while the 5 um element on this unit (code W) suits finer components such as precision valves, cylinders with close tolerances or instrumentation. Drain type matters: differential-pressure drains automatically on element loading, automatic drains empty on a timer-free level basis, and manual drains need operator attention. Gauge style and scale (square embedded or external round; MPa, psi or bar) are decodable choices, as are thread (PT standard, G or NPT to order) and the optional or included bracket. This unit is the low-pressure regulator type; its exact regulating range is not published, so confirm it with us. Because flow is published as curves and not a single rating, 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 this series as curves, not as a single rated number, so we do not quote a figure that could be misleading. Send us your application's air demand and line conditions and we will confirm the correct size and the relevant flow-curve data from the datasheet before you order.
The standard 40 um element suits general-purpose protection of cylinders and valves. The 5 um element fitted to this unit is for finer downstream equipment - precision valves, instrumentation or close-tolerance actuators - where smaller particles cause sticking or wear. If your circuit only needs coarse protection, the 40 um version of the same size is available.
