The AirTAC AirTAC GFR200-06T Filter Regulator 1/8 in NPT, 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 GFR200-06LNWTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is the size 200 unit with a 1/8 in NPT port, fitted with the fine 5 um filter element (code W) for applications that need cleaner air than the standard 40 um grade. It is the low-pressure type (code L), so the regulation range is narrower than the standard unit - the exact range is not published in the catalogue and we will confirm it against your application on request. The bowl is differential-pressure drained, polycarbonate (size 200), and a check valve (code K) is fitted so downstream pressure is held if the upstream supply drops. No gauge is fitted (code N) 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 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against your application before ordering.

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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 clean, regulated low-pressure air to laboratory analysers or test benches, where the 5 um element protects sensitive pneumatic components from water and fine particulate.
Regulating supply pressure to a light-duty clamping or positioning cylinder on a small assembly fixture, with the check valve holding the set pressure if the main air supply is interrupted.
Mounting inside a compact control panel or machine sub-panel as the point-of-use air treatment station for a low-flow control circuit, using the included bracket and the 1/8 in NPT port.
Work through the decodable choices in order. Size 200 with a 1/8 in NPT port is the smallest step in the GFR range - step up to 300, 400 or 600 if your circuit needs a larger port; we will confirm the flow curve against your required flow on request, since AirTAC publishes flow as curves rather than a single rating. The 5 um element (code W) suits air tools, instruments and valves that need finer filtration than the standard 40 um grade. The differential-pressure drain (the default) bleeds accumulated condensate automatically as flow passes through; choose automatic or manual drain variants if your duty cycle calls for it. This is the low-pressure type, so confirm its regulation range with us before ordering. No gauge is fitted - gauge options and MPa, psi or bar scales can be added on other variants. NPT is specified here; PT is the catalogue standard and G (BSPP) is also available to order. A mounting bracket is included.
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 GFR flow as curves rather than a single rated figure, so no single flow number can be quoted here. Tell us your required flow and operating pressure and we will confirm the sizing against the datasheet curve on request before you order.
Code L marks this as the low-pressure regulation variant of the GFR200, intended for circuits regulated below the standard unit's range; the exact range is not published in the catalogue, so we confirm it on request. Code N means no gauge is fitted - gauge options with MPa, psi or bar scales are available on other GFR200 variants, and a separate gauge can be added to your circuit.
