Product Name: Bag Filter Venturi Tube Aluminum Material Model NO.: 155x170 Cartridge Installation: Vertical Lifting Filter Bag Environment: High-Temperature Filter Bag Sectional Shape: Round Bag Filtration Grade: Medium Filter Usage: Dust Filter Type: Pocket Filter Filter Bag Filter: Outside the Filter Type Cartridge Filter: Venturi Medium Material: Dust Air Material: Aluminum or Steel Trademark: XIE CHANG Transport Package: Carton Specification: 155x170 Origin: China Product Description Ventury tube filter is main functions as an inductor of second airflow. When the filter bag removes dust and high-speed airflow passess through Venturi, it can induce a seond airflow that is 5~8 times the blowing compressed air into the filter bag, which is sharply expanded in a moment. Because of the reverse action of airflow, dust deposited on the filter bag will drop off. Venturi tube improves the pulse blowing strength and effect greatly. Consumption of compressed air is lowered and energy is saved.
