Cages can be fitted with either collars or Venturis or both, depending on the filter system they are required for.
The inclusion of a venturi increases the velocity of the air-flow through the filter and increases filtration efficiency particularly where longer cages are used.
Hilson Filtration Products Ltd can design, source and fit a wide range of venturis in various material specifications to suit most applications.
