Pussisiivilä

Pussisiivilä is a Finnish term that translates to "bag filter" or "sock filter." It refers to a type of industrial filter used to remove solid particles from a fluid, typically air or gas. These filters consist of a series of cylindrical or rectangular fabric bags, known as filter sleeves, suspended within a housing.

The dirty fluid enters the housing and is forced to pass through the fabric of the filter bags. The solid particles are captured on the inner or outer surface of the bags, depending on the design, while the cleaned fluid passes through. Periodically, the captured dust or particles are removed from the bags through a cleaning process. Common cleaning methods include shaking, vibrating, or using a pulse of compressed air to dislodge the accumulated material.

Pussisiivilät are widely employed in various industrial applications, including dust collection in manufacturing plants, power generation facilities, cement production, and food processing. Their effectiveness in capturing fine particles makes them essential for environmental control and maintaining air quality. The choice of filter material depends on the nature of the particles, the temperature of the fluid, and the required filtration efficiency. Regular maintenance and cleaning are crucial to ensure the optimal performance and longevity of a pussisiivilä system.
