The AirTAC GFR20008LF3WTK AirTAC Filter Regulator 1/4 in NPT, 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 GFR20008LF3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single compact body. This 200-size unit is fitted with a 1/4 in NPT port, a 5 um filter element (the finer W grade, versus the standard 40 um), a low-pressure regulator type, a differential-pressure drain on the bowl, a reverse/check valve, and an embedded square gauge scaled in bar. The polycarbonate bowl lets you see condensate at a glance, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR200 series, one of four sizes (200/300/400/600) covering a range of ports from 1/8 in to 1 in, with manual, automatic or differential-pressure drain options, 40 um or 5 um filtration, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. 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.

On a carton-sealing or wrapping line, the 5 um element protects downstream valves from water and fine debris while the low-pressure regulator holds a gentle setpoint for delicate actuation, and the check valve keeps the setting stable if upstream supply dips.
At a bench or pilot-scale process skid, the 1/4 in NPT unit filters condensate and particles down to 5 um and regulates a low, steady pressure to instruments and small pneumatic devices, with the bar-scaled square gauge giving a clear local reading.
Feeding spray guns or coating heads on a production line, this filter regulator strips water and fine particulate that would spoil finish quality, holds the low delivery pressure the applicator needs, and its differential-pressure drain sheds collected condensate without operator attention.
Choose the size and port step against the air your circuit actually uses: this unit is 200 size with a 1/4 in NPT port, and larger sizes (300/400/600) carry larger ports and more flow. The 5 um W-grade element suits downstream equipment that needs finer filtration than the standard 40 um; the differential-pressure drain bleeds condensate automatically as flow passes through, with no manual draining routine. The embedded square gauge is scaled in bar; external round gauges and MPa or psi scales are options. This is the low-pressure regulator type, so confirm its adjustment range against your setpoint - we will confirm exact figures on request. NPT is fitted here; PT (standard) and G threads are catalogue alternatives, and the mounting bracket is included.
Because AirTAC publishes flow as curves rather than 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. The reflux valve permits reverse flow 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 number here. Tell us your operating pressure and the air your application consumes, and we will confirm the flow curve and sizing from the datasheet on request.
The W in the code selects the finer 5 um filter grade instead of the standard 40 um element. It is the right choice when downstream equipment - fine valves, applicators or instruments - needs cleaner air than the standard grade provides. If in doubt, we can confirm which grade suits your application.
