The AirTAC GFR20006LC1WTK AirTAC Filter Regulator NPT1/8 Low-Pressure 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 GFR20006LC1WTK is a GFR200-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration uses the 1/8 in (NPT1/8) port, the smallest step in the GFR range, and is the low-pressure (L) type; the exact regulation range of the low-pressure version is not published, and we confirm it on request. It carries the 5 um filter element (code W, tighter than the 40 um standard), the differential-pressure drain (the default), a round pressure gauge scaled in MPa (code C1), and a built-in reverse/check valve (code K) that protects against reverse flow. Mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing). The bowl on this 200 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT (standard), G and NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and gauge and scale choices. AirTAC publishes flow for this family as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application on request - just ask.

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.

Feeds filtered, regulated air to the small clamping cylinders on an electronics assembly fixture. The 5 um element protects tight-tolerance control valves, and the reverse/check valve guards the circuit against reverse flow if the shop supply dips.
Supplies clean, low-pressure air to a lab test rig or instrument bench. The round MPa gauge gives a direct pressure readout at the bench, and the differential-pressure drain bleeds off collected water without interrupting the run.
Provides filtered, regulated air to the pilot circuits of pneumatically actuated process valves on a small skid or process line. The low-pressure (L) type and the compact NPT1/8 port fit tight pilot panels, and the included bracket simplifies mounting.
Choose the size by port and air demand: GFR200 is the 1/8 in step in a range that runs 200/300/400/600 up to 1 in, so step up if your line needs more flow - and ask us to confirm sizing, because AirTAC publishes flow as curves, not a single rating. This unit is the low-pressure (L) type, so confirm it matches your circuit pressure before ordering. Filtration here is the 5 um (W) element rather than the 40 um standard; pick 5 um where downstream equipment needs finer air. The differential-pressure drain is the default on this model; automatic (A) and manual (M) drains are available in the family. Code C1 fits the round external gauge scaled in MPa (an embedded square gauge is the standard arrangement; psi and bar scales are offered). The thread is NPT (T); PT is the standard thread and G is also available to order. Bracket is included, and the K code adds a reverse/check valve.
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 family as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet on request.
L is the low-pressure type; C1 fits the round external gauge scaled in MPa; W is the 5 um filter element instead of the 40 um standard; and K means a reverse/check valve is fitted. The drain is the differential-pressure type (the default), and the thread is NPT - PT is the standard thread and G is also available to order.
