The AirTAC GFR20006LF1WT AirTAC Filter Regulator NPT 1/8, 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 PT1/8" 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 GFR20006LF1WT is a size-200 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is a low-pressure type, so it is intended for circuits held at reduced working pressure rather than full line pressure. It carries a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge reading in MPa so the set pressure is visible at a glance. The port is 1/8 in with NPT thread, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and is offered with a choice of drain type, filter grade (40 um standard or 5 um), gauge style and scale, and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, 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 carton-sealing or wrapping line where actuators and clamps are held at reduced pressure, this filter regulator cleans the supply of water and chips and holds the set pressure, with the MPa gauge letting an operator verify the setting during changeover.
Bench-top test rigs and analytical instruments need air that is free of water and fine particles and supplied at a gentle, stable pressure. The 5 um element and low-pressure regulation of this unit make it a compact supply point for such benches, with the included bracket fixing it to the frame.
Small cylinders that divert, stop or index product on a conveyor line run best on clean air at a reduced, repeatable pressure. This filter regulator mounted at the line drop conditions the supply and lets the setter read and hold the working pressure on the square gauge.
Start with the size and port: the 200 series with a 1/8 in NPT port suits the smallest branch lines; step up to 300/400/600 when the line and required flow grow. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit is already specified as the low-pressure type, 5 um filtration, differential-pressure drain and a square MPa gauge. If you need a different combination, the family also offers 40 um standard filtration, automatic or manual drains, an external round gauge with MPa, psi or bar scales, and PT or G threads instead of NPT. A mounting bracket is included with this configuration.
On regulation: this is the low-pressure (L) version of the GFR200, and its exact adjustment range is not published in the material we hold, so confirm the set pressure you need with us before ordering. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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 a l/min or SCFM figure here. Tell us your line size and application and we will confirm the flow figures from the datasheet on request before you order.
The code W in GFR20006LF1WT selects the finer 5 um filtration grade instead of the 40 um standard, which suits applications sensitive to fine particles. The blank drain position is the differential-pressure drain, which passes collected condensate automatically as air flows through, so no manual draining routine is needed at this drop.
