The AirTAC AirTAC GFR20006LF2WTK Filter Regulator NPT1/8, 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 GFR20006LF2WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one compact body. This 200-size unit is configured with a 1/8 in NPT port, a fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a low-pressure regulator type for circuits that run well below standard line pressures. A square pressure gauge (psi scale) is fitted so the set pressure is visible at the unit, and a reverse/check valve (code K) holds downstream pressure if the upstream supply is interrupted. The polycarbonate bowl suits the 200 size, 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, and each size can be ordered with manual or automatic drain, a 40 um or 5 um element, different gauge scales, G (BSPP) or NPT threads in place of the PT standard, and with or without bracket and gauge. Because AirTAC publishes flow for this family as curves rather than a single rated figure, we confirm the exact flow and 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.

Feeds filtered, regulated air to pilot valves and small actuators on a cartoning or wrapping line, where the 5 um element protects sensitive valve seats and the low-pressure regulator type matches circuits run below standard line pressure.
Conditions the supply to clamps, cylinders and pneumatic sensors on a test bench, with the square psi gauge giving a direct local reading and the check valve holding the set pressure if the bench supply is momentarily lost.
Mounted at the machine inlet with the included bracket, it removes water and fine particulate from the shop-air drop and regulates pressure for air bearings, coolant nozzles or tool-clamp circuits on a single 1/8 in NPT take-off.
Start with the port step: this 200-size unit carries a 1/8 in NPT port, the smallest in the GFR range, so step up to 300/400/600 if your line flow demands a larger connection. Choose the filter grade to match the duty: 40 um is the standard general-purpose element, while the 5 um element fitted here (code W) suits finer downstream components. Drain choice matters: differential-pressure drain (fitted here) needs no operator attention, automatic drain suits unattended installations, and manual drain is the simplest option where an operator is on site. Gauge scale is selectable (MPa, psi or bar) and an external round gauge is available as an alternative to the embedded square gauge. Thread is PT as the AirTAC standard, with G (BSPP) and NPT as order options - this unit is specified in NPT. A bracket is included, and code K adds a reverse/check valve. Note that the low-pressure regulator type is intended for circuits below standard line pressure; its exact adjustment range is not published in the catalogue, so ask us to confirm it against your set pressure. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the G-series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and expected air consumption, and we will confirm the flow from the datasheet and check the sizing against your application before you order.
Code L selects the low-pressure regulator type, intended for circuits that run below standard line pressures; its exact adjustment range is not published in the catalogue, so ask us to confirm it for your set pressure. The differential-pressure drain needs no operator action: as air flows through the unit, the pressure difference across the element automatically bleeds collected condensate from the polycarbonate bowl.
