The AirTAC GFR20006MLF3WT 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 GFR20006MLF3WT is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 5 um element (the finer W grade, against the 40 um standard) and holds a regulated downstream pressure, with the fitted square gauge reading in bar. This is the low-pressure type, sized 200 with a 1/8 in NPT port, manual drain, and a polycarbonate bowl. 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 published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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. |
| (blank) | No reverse-flow valve (the default). |
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 laboratory or QC test bench running small air cylinders and actuators, this low-pressure filter regulator cleans the supply through the 5 um element and lets a technician set and read a stable reduced pressure on the bar gauge, with the manual drain bled off between sessions.
Feeding positioners, transducers and small pneumatic control devices on a process panel, the compact 200 size and 1/8 in NPT connection fit tight manifolds, while fine 5 um filtration protects sensitive instrument internals from water and particulate carryover.
On a packaging line where low-pressure air drives glue applicators and spray nozzles, this unit filters the supply and regulates it to the head's setting, with the manual drain cleared during changeover and the included bracket securing the unit to the machine frame.
The 200 size with a 1/8 in NPT port suits compact lines and point-of-use drops; step up to 300, 400 or 600 when the circuit demands larger ports and more flow. Choose the manual drain on this model where an operator can bleed the bowl on a routine, or specify automatic or differential-pressure drain where the unit runs unattended. The 5 um element (code W) is the right call for downstream components sensitive to finer particles; the 40 um standard grade suits general protection.
Gauge scale is selectable (MPa, psi or bar) and this unit carries the embedded square gauge in bar; an external round gauge is optional. PT is the standard thread, with G (BSPP) and NPT as order options - this code is the NPT version. A mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back 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 figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code selects a manual drain: an operator opens the bowl drain to expel collected water. If the unit will run unattended, the same GFR200 family is available with automatic (code A) or differential-pressure (blank) drain instead. This unit also carries the 5 um W-grade element, the low-pressure regulator type, and a square gauge reading in bar.
