With the-channel screen changers additional slide valves are used at the backflush channels. There is no interference of the process during backflushing.
 
Features included
1,Continuously working melt filter
2,4 working stations 
three,venting groove can discharge the gas mixed in the raw material 
4, no interference during the process of backflushing
5,the screen cleaning reached 85%
6, long life span of the filtration screen pack/mesh , it owning to up to 100 times backflushing at most.
