Filter cages and venturi are used in various applications as part of industrial filtration. They are metal structures used with filter bags in baghouses to assist with optimising bag performance and durability. At Sefar Filter Pure, we produce filter cages and venturi according to the needs of the installation or the measurements provided by the customer. Additionally, our service team can assist with installation and supervision.

The type of cage used depends on the design of the baghouse, top or bottom load as well as the type of fabric used for the filter bags. This informs the type of cage that will be used and the number of bars the cage should have.

Venturi are cone-shaped devices that are used to assist in speeding up the air that is pulsed through the bag. They act as turbo boosters by creating negative pressure to pull down additional air. This ensures a clean with an efficient sonic ripple. They are produced in galvanised steel, coated steel and stainless steel.
