The AirTAC GFR20008MLC3WTK AirTAC Filter Regulator NPT1/4, 5 um 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 PT1/4" 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 GFR20008MLC3WTK is a size-200 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is built for 1/4 in NPT ports, carries a 5 um filter element (the finer of the two published grades), drains by hand via its manual drain, and is the low-pressure regulator type. A round pressure gauge scaled in bar is fitted, a reverse/check valve is installed, and the mounting bracket is included. The polycarbonate bowl lets you see accumulated condensate at a glance.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G and NPT thread options. Flow figures for this series are published as curves rather than a single rating, so contact us and we will 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.

|---|---|
| 08 | Port size PT1/4". 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. |
| 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. |
| 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 CNC fixture line running 1/4 in drop legs, this unit filters the supply to 5 um and holds a steady low regulated pressure to the clamping cylinders, with the check valve helping hold clamp pressure if the main supply drops.
Bench-top test rigs and sample-prep stations fed at 1/4 in need clean, gently regulated air; the 5 um element and manual drain suit a station an operator attends daily, with the bar gauge giving a direct line-pressure readout.
On a carton-sealing or bagging machine with 1/4 in air drops to small actuators, this filter regulator keeps water and fine particulate out of the valves while the low-pressure type regulator matches the actuators' modest working pressure.
For this unit the meaningful choices are already fixed in the code: size 200 with a 1/4 in NPT port suits lines plumbed at 1/4 in; the 5 um element (code W) is the right pick where downstream valves, cylinders or instruments are sensitive to finer particles than the 40 um standard element catches; the manual drain means an operator opens the bowl drain periodically, which suits stations that are visited regularly - choose an automatic or differential-pressure drain variant instead for unattended duty. The round bar gauge gives a local pressure readout, and the fitted reverse/check valve holds downstream pressure if upstream supply is interrupted.
Because AirTAC publishes flow for this series as curves and not as a single rated number, we do not quote a flow figure here. Send us your required flow and pressure conditions 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 performance curves rather than a single rated figure, so we do not quote a flow number. Tell us your required flow and working pressure and we will confirm the datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: condensate collects in the polycarbonate bowl and an operator opens the drain periodically. If the installation runs unattended, the GFR200 series is also available with an automatic drain (code A) or the differential-pressure drain that is the series default - ask us for those variants.
