The AirTAC GFR20006LF2WT AirTAC Filter Regulator NPT1/8 5um 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 PT1/8" 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 GFR20006LF2WT is a GFR200-series filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single compact body. This configuration is built for low-pressure circuits, with a 5 um filtration element (finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge reading in psi so the setpoint is visible at the unit. The 1/8 in NPT port suits compact lines and point-of-use drops, the polycarbonate bowl lets you see the condensate level, and 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).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, standard or low-pressure regulator types, MPa/psi/bar gauge scales, and G/NPT thread options. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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. 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 machining cell where soft-jaw clamps or hold-downs must be set well below standard line pressure, the low-pressure regulator type gives fine control, while the 5 um element keeps the clamp cylinders' seals and quick-exhaust valves free of grit and water.
Blow-off nozzles and air knives on a filling or labelling conveyor run continuously and sit far from the plant FRL. This unit filters the supply to 5 um, holds a stable low setpoint for gentle product handling, and its differential-pressure drain purges condensate as the air flows.
Spray and atomizing heads in coating benches are sensitive to both pressure drift and particulates. The square psi gauge makes the setpoint easy to verify at a glance, the 5 um grade protects the fine nozzle orifices, and the compact 1/8 in port fits tight panel space.
Start with the port step: this unit is size 200 with a 1/8 in NPT port, the smallest in the GFR range - move up to GFR300/400/600 if the line grows. This code carries the 5 um (W) element; choose the blank-code 40 um version where only coarse water and particle removal is needed, and keep 5 um where downstream valves or instruments demand cleaner air. Drain choice matters: the differential-pressure drain here is maintenance-light but only purges while air flows; pick automatic (A) for intermittent-flow lines or manual (M) where you want scheduled draining. The regulator in this code is the low-pressure (L) type - select it for circuits set well below standard working pressures, and the standard type elsewhere. Gauge scale is psi here (2); MPa (1) and bar (3) scales exist, and an external round gauge is optional. Thread comes as NPT (T) on this code, with G (BSPP) and PT available to order; a bracket is included.
One honest note before you order: AirTAC publishes flow for this series as curves, not a single rated figure, so we cannot quote a number here. Send us your application details and we will confirm sizing against the datasheet curves on request.
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 number here. Tell us your line pressure, set pressure and downstream demand, and we will confirm the sizing against the datasheet curves on request.
The W in the code selects the finer 5 um filtration grade instead of the 40 um standard - worth it when protecting valves, cylinders or instruments downstream. The blank drain position means the differential-pressure type: it purges collected condensate automatically while air is flowing, with no manual draining, but it relies on flow to do so. If your line runs intermittently, ask us about the automatic-drain (A) version of the same unit.
