The AirTAC GFR20006MLJF1WTK AirTAC Filter Regulator NPT 1/8 in 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR20006MLJF1WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the compact size 200 unit with a 1/8 in NPT port, the fine 5 um filter element (code W), a manual drain on the bowl, and the low-pressure regulator type for applications set well below standard line pressures. A square pressure gauge scaled in MPa is fitted, and a reverse/check valve is built in to hold the downstream setting if the upstream supply is interrupted. The bowl on this size is polycarbonate, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes 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, standard or low-pressure regulation, gauge and thread options, and an optional mounting bracket. Rated flow for this series is published as curves rather than a single figure, 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.
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

A size 200 filter regulator with the low-pressure type suits the clamping circuit of a small machining or welding fixture, where air cylinders are set to a gentle, repeatable holding pressure and the 5 um element protects the valve and cylinder seals from fine particles.
On a laboratory or QC test bench running small pneumatic actuators or air bearings, this 1/8 in NPT unit filters the shop supply to 5 um and regulates it down to the low test pressure, with the MPa gauge giving a direct reading at the rig.
A spray booth or small coating station benefits from the low-pressure regulator type: the unit cleans the compressed air to 5 um, drops it to the gentle pressure the gun needs, and the check valve keeps the setting stable if the shop supply dips.
Start with the port step: this unit is size 200 with a 1/8 in NPT port, the smallest in the GFR range, so match it to the line size and the air demand of the circuit. Choose the drain to suit access: this model has a manual drain, which suits stations someone visits routinely; automatic or differential-pressure drains suit unattended installations. The 5 um element (code W) is the finer of the two published grades, the standard being 40 um, so pick 5 um where downstream equipment is sensitive to finer particles. The low-pressure regulator type is intended for circuits set well below standard line pressures; ask us to confirm its exact adjustment range, as it is not published in the same table as the standard type. The fitted square gauge reads in MPa, with psi or bar scales and an external round gauge available as options. NPT is the thread on this unit; G (BSPP) and PT are the other catalogue options. A mounting bracket is available if you want the unit secured rather than line-mounted.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm the correct size against the datasheet 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 performance curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing against the datasheet on request before you order.
The M in the code selects the manual drain on the filter bowl: collected water is released by opening the drain by hand. That suits stations visited routinely. If the installation is unattended, the same series is available with an automatic drain (code A) or the differential-pressure drain that is the default, and we can quote that variant.
