Tubular-Plane-Filter-Device

High precision tubular filter device, with tubular filter and plane filter (Ø 45 mm).

Filter device for dust range from 20 to 2000 mg/m³  (absolut 1-2 g).

• for IN- and OUT-Stack-measurements,
• construstion according to VDI 2066, page 2 and EN 13284.

The tubular section can be stuffed with glass or quartz wool or with thimbles.

 A plane filter (Ø 45 mm) following the tubular section to retains broken fibres. By this the detection limit is reduced and the reproducibility enhanced.

Data:

• max. sampling rate: 4 m³/h,
• incl. filter cartridge with cone,
• plane filter holder,
• seals,
• entrance: Internal thread G ½,
• exit: External thread G ½,
• outer diameter: 55 mm,
• length: 145 mm.

The filter can be converted to a plane filter device. For this purpose must be used the inlet cone 7.22-K, see here.
