The AirTAC GFR200-06 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 GFR200-06 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is fitted with a 1/8 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. It is the low-pressure (L) type, intended for circuits that run at reduced pressure, and the exact adjustment range for this variant is not published in the catalogue - we will confirm it on request. A square embedded gauge scaled in bar is fitted, a reverse/check valve is included to hold downstream pressure when the supply is lost, and the polycarbonate bowl is supplied with a mounting bracket.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for 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.

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 filtered, pressure-controlled air to laboratory analysers or sample-preparation panels, where the 5 um element protects sensitive pneumatic components and the low-pressure type matches a reduced-pressure circuit.
Conditioning the air for the control valves and actuators on a packaging or labelling line, with the check valve holding the set pressure if the main supply dips and the bar gauge giving operators a clear setpoint reading.
Supplying regulated air to a pneumatic clamp or small workholding fixture at a machine bench, where the compact 200-size body, included bracket and 1/8 in NPT port suit tight panel mounting.
Start with the port: this unit is 1/8 in NPT, the smallest step in the GFR range, so match it to the line size and check that the flow curve at your working pressure supports the demand - we can confirm the curve on request because no single rated flow figure is published. The 5 um element (code W) suits air that feeds sensitive valves or instruments; choose the standard 40 um grade for general shop-air protection. The differential-pressure drain is the default and needs no operator attention; an automatic or manual drain can be ordered instead if your duty cycle calls for it. The fitted square gauge reads in bar; round gauges and MPa or psi scales are order options, as are G (BSPP) and NPT threads in place of the PT standard. A mounting bracket is included with this configuration.
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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the datasheet curve and check the sizing for your application before you order.
The W in the code GFR20006LF3WTK specifies the finer 5 um filter element instead of the standard 40 um grade, which suits air feeding sensitive valves or instruments. The trailing K specifies a reverse/check valve, which holds the regulated downstream pressure if the upstream supply is interrupted. Both are catalogue options you can order with or without on other GFR200 units.
