3. Advantage
The Star filter bags extend the filter surface, the increaing
filter area compared to ordinary round ones is below,
Filter area increasing (%)

So
• longer bag service life
• increase the air volume of existing dust collectors to increase
production capacity
• lower emission
• reduce energy consuption
• reduce operation cost
• reduce pressure drop
• lower pulse jet pressure and frequence
• small bag house and building area
• lower the filter velocity
4. The Match of Star bags and Cages
Star filter cages are special designed to fit star bags, which is
not like ordinary ones with tigh match. Star cages is a kind of
loose match of star bags, which is good for deashing.
