The AirTAC GFR20006LF3T AirTAC Filter Regulator NPT1/8 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR20006LF3T is an AirTAC GFR200-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration is the 200 size with a 1/8 in NPT port, the low-pressure regulator type, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. A square pressure gauge with a bar scale is fitted so the set pressure is visible at a glance, and a mounting bracket is included for secure panel or wall fixing.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, gauge scale choices, and G or NPT thread options in addition to the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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.

Spray booths and coating heads that run below conventional regulator bands need clean, gently regulated air. This low-pressure GFR filters water and particulate and holds the reduced pressure, with the bar-scale gauge showing the setpoint.
Bench-top clamping and hold-down fixtures need filtered air and a stable reduced pressure at the point of use. The 1/8 in NPT port suits compact drop lines, and the included bracket fixes the unit beside the fixture.
Test rigs and lab apparatus fed from a shop-air header need particulate- and water-free air at a controlled low pressure. The differential-pressure drain keeps condensate moving out without manual attention, and the square gauge gives a clear bar reading.
Start with the port step: this unit is the 200 size with a 1/8 in NPT port, so match it to the line size and the flow your circuit needs - larger GFR sizes step up in port and flow capacity. The low-pressure type here is intended for circuits that work below the standard regulator band; if your process runs at conventional shop-air pressures, a standard-type GFR may be the better fit. The 40 um element is the standard grade for general air preparation; specify the 5 um W-code element where finer filtration is required. Drain choice matters: the differential-pressure drain on this unit needs no operator attention, while automatic and manual drains are order options. The fitted square gauge reads in bar; MPa and psi scales are available. Thread is NPT here, with G and PT as catalogue options, and a mounting bracket is included. Because flow is published 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. 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 figure here. Tell us your line pressure, set pressure and required flow, and we will confirm the datasheet curve and check the sizing for your application before you order.
The L in the code marks the low-pressure regulator type, intended for circuits that operate below the standard regulation band; the exact range for this variant is not published, so ask us to confirm it for your setpoint. The drain code is blank, which means the differential-pressure drain: condensate collected in the PC bowl is discharged automatically when the pressure drop across the 40 um element is high enough, with no manual draining needed.
