The AirTAC GFR20006LF3TK AirTAC Filter Regulator NPT1/8 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR20006LF3TK is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air at the standard 40 um grade while regulating downstream pressure, in a low-pressure type configuration. This unit has a 1/8 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a polycarbonate bowl, an embedded square gauge scaled in bar, a reverse/check valve fitted to hold downstream pressure, and a mounting bracket included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, drain types, 40 um or 5 um filter grades, gauge scales and low-pressure or standard regulator types. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Filtered, regulated air to clamp cylinders on a milling or turning fixture, with the check valve holding the set downstream pressure if supply dips and the bar gauge giving the operator a direct reading.
The low-pressure regulator type suits bench-top automation and analytical-instrument actuation that runs on reduced supply pressure, with 40 um filtration protecting small valves and cylinders.
Conditioned air for pilot-operated and actuated valves on a treatment skid, where the differential-pressure drain keeps condensate off the valve internals during continuous operation.
Size and port: the 200 size with a 1/8 in port is the compact step of the GFR range; step up to 300, 400 or 600 where the application needs larger ports and more flow. Drain: differential-pressure (this unit) suits continuous flow; choose automatic (code A) for idle lines or manual (code M) where you want controlled draining. Filter grade: 40 um standard, 5 um with code W for finer protection. Gauge: this unit carries the embedded square gauge scaled in bar; MPa and psi scales and an external round gauge are options. Thread: this unit is NPT; PT and G (BSPP) are catalogue alternatives. A reverse/check valve (K) is fitted and a mounting bracket is included.
Sizing honesty: flow for this series is published as curves, not a single rated figure, so ask us to confirm the datasheet and check the curve against your application before ordering. The low-pressure regulator type has a different adjustment envelope from the standard type; we confirm its exact range on request.
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 rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your inlet pressure and required downstream flow and we will confirm the datasheet curve and check the sizing against your application on request.
The L in GFR20006LF3TK marks the low-pressure regulator type, intended for applications that run at reduced regulated pressures rather than the standard envelope. Its exact adjustment range is not published on the sheet we work from, so we confirm it on request. The unit carries an embedded square gauge scaled in bar so the set pressure can be read directly.
