what is filter cage ventrui

What is a venturi?

Venturis are cone-shaped devices located at the top of a tubular filter bag in a Pulse Jet Dust Collector. At the top of the venturi, it creates a negative pressure for pulling additional air down into the filter elements during pulsing.

We offer customers a full line of properly engineered venturis, available in various materials of construction including spun aluminum, steel and stainless steels. Choose from several styles, already tooled and available for prompt delivery.

Our cage designs can be supplied with an integral venturi, permanently installed. Factory installation assures you of a proper fit – critical to optimal baghouse performance – as well as cost and labor savings.
