The FTI type bag filter is designed for the separation of wood particles and dust from the air. The filter is equipped with a vibratory motor, which performs effective cleaning of the filter elements from dust. The material separated from the air is discharged from the filter using a special loosener and a sluice gate. The FTI type bag filter is manufactured from 1.5-3 mm galvanized steel panels, which makes the structure very durable. The bag filters, which are made of antistatic polyester material, are hung in the filter housing using spring rings.
