Prefilter TVM

LTG’s TVM prefilter is used for coarse filtration. The primary airstream, carrying for example fibres and coarse particles, passes through a rotating filter screen with a mesh with opening matching the particles. The filter screen is continually cleaned by a fixed suction nozzle which does not touch the screen. The pulled off coarse particles are fed to a separator with a conveying fan in a secondary loop.

In a multi-stage dust collection set-up for large air streams a mesh screen is advantageous for large particle separation. Its characteristics are:

• high air permeability
• exact adaptation to the material to be separated with different mesh sizes
• good separation of various size particles
• low maintenance

The advantages of LTG’s TVM pre-filter are as follows:

• regenerative filter unit
• no pressure fluctuations in the systemdue to continuous cleaning
• space saving installation due to the disc shape and the compact design
• optimum face velocity by exact adaptation to the total air quantity
• low pollution of drive elements and easy access by installation on the clean air side
• easy filter media change
• pressure drop is minimized by optimal airflow design
• anti-static, hot air and ATEX models available
