The AirTAC GFR20006LF1TK 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 AirTAC GFR20006LF1TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in one compact body. This 200-size unit has a 1/8 in NPT port, the standard 40 um filter element and a differential-pressure drain that bleeds condensate away as flow resumes. The L in the code marks the low-pressure regulator type, built for circuits that run below standard line pressure, and the K option adds a reverse/check valve so downstream pressure is held if the supply drops. An embedded square MPa gauge is fitted and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which covers 200, 300, 400 and 600 sizes with 1/8 in to 1 in ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um element option and psi or bar gauge scales. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing; the 200-size bowl is PC (polycarbonate). Flow is published as curves rather than a single rating, so ask us to 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. 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.

Feeding low-pressure spray guns and air-assisted applicators, the regulator holds a steady set point while the 40 um element strips water and pipe scale that would otherwise blemish the finish.
On a bench supplying small test fixtures, the low-pressure type lets operators run circuits below standard line pressure, and the fitted check valve holds the fixture setting if the shop supply dips.
Supplying positioners and pilot actuators on a process line, the unit filters the instrument air and keeps pilot pressure stable, with the embedded square MPa gauge giving a direct local readout.
Size the GFR by port and expected flow: 200 is the smallest step, with a 1/8 in port on this unit; step up to 300, 400 or 600 when the circuit needs larger ports and more flow. Choose the drain: differential-pressure (this unit) purges with flow, automatic (A) drains on its own, and manual (M) needs a periodic bowl purge. The standard element is 40 um; specify W for 5 um where finer filtration matters. Gauge scales come in MPa (this unit), psi or bar, and the thread can be ordered in PT (standard), G or NPT. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 the GFR series as curves rather than a single rated figure, so no one number is honest to quote. Send us your line pressure, set point and expected air consumption and we will confirm the datasheet curve for your application on request.
L is the low-pressure regulator type, built for circuits that run below standard line pressure. K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. The 06 sets the 1/8 in NPT port, and F1 the embedded square gauge with MPa scale.
