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
