The AirTAC GFR20006MLC1WTK 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 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 GFR200 series combines water and particulate filtration with pressure regulation in a single compact body, so one component cleans the air and sets a stable downstream pressure. This configuration, GFR20006MLC1WTK, is the size 200 unit with a 1/8 in NPT port, the fine 5 um filter element (code W), a manual drain on the PC bowl, the low-pressure regulator type, a round external pressure gauge scaled in MPa, a reverse/check valve fitted, and a mounting bracket included. The low-pressure type is intended for circuits that run at reduced pressure rather than full line pressure; the exact adjustment window for this type is not published as a single figure, and we confirm it from the datasheet on request. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, manual, automatic or differential-pressure drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated 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.

| 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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.

On a refinish or finishing line, this low-pressure filter regulator cleans the air to 5 um and holds a reduced, stable pressure at the spray gun, with the manual drain cleared during booth housekeeping.
Feeding the low-pressure clamping section of a carton or blister packaging machine, the unit filters incoming air, regulates the clamp pressure, and the check valve keeps clamps from releasing if supply dips.
On a test bench running small pneumatic actuators and instruments, the 5 um element protects sensitive devices and the round MPa gauge gives a clear local pressure readout at the bench.
Start with the port and size: this unit is size 200 with a 1/8 in NPT port, the smallest step in the GFR range, so step up to GFR300/400/600 if your line needs a larger connection and more flow. The 5 um element (code W) suits air that feeds sensitive valves, cylinders or instruments; choose the 40 um standard grade for general-purpose circuits. The manual drain means someone vents the bowl by hand as part of routine checks - if nobody will do that, ask about the automatic or differential-pressure drain versions. The low-pressure regulator type is the right pick when the circuit runs at reduced pressure; we confirm its exact adjustment range from the datasheet. The round MPa gauge is fitted as coded, and square or psi/bar scale gauges are alternatives in the family. Thread is NPT here; PT and G are order options. A bracket is included, and the reverse/check valve holds downstream pressure if the supply drops. Flow 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.
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 number, so we do not quote a figure here. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
The M in the code specifies a manual drain: the bowl is vented by hand as part of routine maintenance. If unattended drainage is needed, GFR200 units are also available with an automatic or a differential-pressure drain - just ask and we will confirm the matching model code.
