The AirTAC GFR20006LC2WTK AirTAC Filter Regulator 1/8 in NPT 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 GFR20006LC2WTK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is specified with a 1/8 in NPT port, the fine 5 um filter element (code W), the low-pressure regulator type, a differential-pressure drain on the bowl, and a reverse/check valve (code K) that holds downstream pressure when the upstream supply is lost. A round external gauge on a psi scale is fitted, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and PT, G or NPT threads. Filter grade, drain type, gauge style and scale, and check-valve fitment are all selectable. Published flow data appears as curves rather than a single rated figure, so we confirm the 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 the small gripper cylinders on a carton or blister packaging line, with the check valve holding the circuit's pressure if the plant air supply dips mid-cycle.
Supplies clean 5 um-filtered air at a controlled low pressure to lab analysers or sample-handling enclosures, where the fine element protects sensitive pneumatic components from water and particulate carryover.
Conditions the air feeding a pneumatic valve positioner or small actuator on a process skid, combining filtration and low-pressure regulation in one body to save panel space and piping.
Size and port set the capacity envelope: this unit is size 200 with a 1/8 in NPT port, the smallest step in the GFR range - step up to 300, 400 or 600 if your line needs larger ports. The 5 um element (W) suits points of use that need cleaner air than the 40 um standard grade; the differential-pressure drain bleeds accumulated condensate automatically as flow passes through, with no manual draining routine. The low-pressure regulator type is intended where controlled pressures sit below the standard type's range - we confirm the exact adjustment window from the datasheet on request. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are also catalogue options.
Flow for GFR units is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order. NPT is specified here; PT and G (BSPP) threads are order options, and the mounting bracket is included with this code.
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 performance as curves across the pressure range rather than as a single rated figure, so there is no one flow number we can honestly quote. Tell us your working pressure and required flow and we will confirm the sizing from the datasheet on request before you order.
W is the filter grade: this unit carries the fine 5 um element instead of the 40 um standard. K means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is interrupted. The code also decodes the low-pressure regulator type (L), a round psi-scale gauge (C2), NPT thread (T), and the differential-pressure drain on the bowl.
