The AirTAC GFR20006LF2WGK AirTAC Filter Regulator G1/8 (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 AirTAC GFR20006LF2WGK is a compact GFR200-series filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a G1/8 port, a 5 um filtration element (the finer of the two published grades), the low-pressure regulator type, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge scaled in psi, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. The polycarbonate bowl lets you see the condensate level at a glance, and a mounting bracket is included for secure panel or frame installation.
This is a genuine AirTAC part from the G-series air-treatment range, which spans 200, 300, 400 and 600 sizes with port options from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, and PT, G or NPT threads. Flow is published by AirTAC as selection curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures 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.

On a carton-sealing or case-packing line, this unit filters the supply air to 5 um, holds a steady low regulated pressure to the clamping cylinders, and the check valve keeps the clamps from releasing if the plant air drops.
For a bench running pneumatic gauges or test actuators, the 5 um element protects sensitive instruments from water and particles while the psi-scaled square gauge gives a direct reading at the bench.
Feeding the pusher and diverter cylinders on a sorting conveyor, the unit delivers clean, regulated low-pressure air, and the differential-pressure drain sheds condensate during continuous running without operator attention.
Start with the size and port: the GFR200 size with a G1/8 port is the smallest step in the range, so match it against the air consumption of the machine it feeds and step up to a 300, 400 or 600 unit if the line needs more. This unit carries the W-grade 5 um element - choose it where downstream valves, cylinders or instruments need finer air than the 40 um standard grade provides; if coarse protection is enough, the standard grade costs less to run. The low-pressure regulator type in this code is intended for applications working below the standard regulator band; the exact adjustment range is not published on the sheet we work from, so confirm it with us. The differential-pressure drain is the default: it needs no manual attention but relies on flow to purge, so pick an automatic drain for intermittently used lines or a manual drain where you want full control. The square gauge is scaled in psi here (MPa and bar scales are also available), and the fitted reverse/check valve is worth having on circuits where a loss of supply must not dump downstream pressure. Thread is G here; PT is the standard and NPT is available to order, and a bracket is included.
Because AirTAC publishes flow only as curves and not as a single rated number, we cannot quote a rated flow for this unit. Send us your application details and we will confirm sizing against the datasheet curves 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 selection curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us the air demand of your application and we will confirm the sizing against the datasheet curves on request before you order.
The W code in the model number selects the 5 um filtration grade instead of the 40 um standard, giving finer removal of water and particulate for sensitive downstream equipment. The K code fits a reverse/check valve, which holds the regulated downstream pressure if the upstream supply is interrupted. Both are factory-fitted in this configuration; the 40 um grade and a version without the check valve are available as separate order codes.
