LTG's TVM pre-filter is used for coarse filtration. The primary airstream, carrying fibres and coarse particles, passes through a rotating filter medium with a mesh width matching the particles. The filter medium is continually cleaned by means of a fixed stripper nozzle which does not make contact with it. The separated and extracted coarse particles are fed to a separator by means of a conveying fan in the secondary circuit.
To filter out the coarse particles from large air streams, it is best to use an appropriate prefilter screen. Its characteristics are:
- high air permeability
- exact adaptation to the material to be separated by using different mesh sizes
- good separation of various size particles
- low maintenance
The advantages of LTG’s TVM pre-filter:
- regenerative filter unit
- no pressure fluctuations in the suction systemdue to continuous cleaning
- space saving installation due to the disc shape and the compact design
- optimum velocity is achieved by exact adaptation to the total air quantity
- no fiber contamination of drive elements and easy Access by installation behind the prefilter screen
- easy filter media Change
- pressure drop is minimized by optimal airflow design
