The AirTAC GFR20008F1WT 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 GFR20008F1WT 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 piped 1/4 in NPT, carries the fine 5 um filtration element (code W) instead of the standard 40 um, and drains condensate by differential pressure, so the bowl empties automatically as flow passes through it - no manual draining routine. The embedded square gauge reads outlet pressure in MPa, and the standard regulator covers a 0.15-0.9 MPa (20-130 psi) adjustment range at up to 1.0 MPa (145 psi) inlet.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, a reverse/check valve, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 the air cylinder of a bench-top pressing or riveting station: the 5 um element keeps scale and pipe debris out of the cylinder seals while the regulator holds a steady set pressure stroke after stroke.
Conditioning the supply ahead of the directional valves on a cartoning or wrapping line, where clean, dry, correctly regulated air prevents erratic valve shifting and product-jam downtime.
Mounted at a 1/4 in outlet on a shop air ring main, it filters the compressor's carryover and lets the operator dial in the pressure a die grinder, impact driver or air gun actually needs.
Size this unit by the flow your line needs: the 200 frame with its 1/4 in port is the entry step, and moving to 300, 400 or 600 buys larger ports and more flow - we will confirm the curve against your demand before you order. The 5 um element (this code, W) suits air that feeds sensitive valves, cylinders or instruments; the standard 40 um element is fine for general actuation. The differential-pressure drain fitted here is the fit-and-forget choice; choose automatic or manual drain codes if your duty cycle or maintenance plan calls for it. The square gauge reads MPa; psi or bar scales and an external round gauge are orderable. PT is the standard thread and G or NPT are catalogue options - this unit is the NPT version. A mounting bracket is included; a no-bracket (J) version exists. Flow is published as curves, not a single rating, so 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, not as a single rated number, so we do not quote one. Send us your line pressure, set pressure and air demand and we will confirm the datasheet curve and the right size (200/300/400/600) for your application before you order.
The W in the code GFR20008F1WT selects the fine 5 um filtration grade. It is the right choice when the downstream air feeds precision valves, cylinders or instrumentation; the standard 40 um element remains available on other GFR codes for general actuation duty.
