Bag Filter ‐ Coarse and Medium Dust
Bag coarse filter is mainly used to filter and remove ≥5μm dust particles in air conditioning system. The ordinary flat filter is 592×592, provided with 3‐12 parallel bags, bag depth generally ranging from 250~900mm. Ultasound welding spacers between individual bags ensure an even airflow throughout the filter, which allows dust loading and even distribution. This results in a long service life of the filter and reduces energy costs. The bag can be provided with separation fence inside to effectively increase the filtration area.
