Hangzhou philis filter technology co.,ltd. has grown up to be one of leading manufacturer on dust
filtration&spare parts in China.We have imported filter needle
felt production line ASSELIN from France and we can produce very
good quality non-woven products according customer's requirment.
Based on 8 needle felt production line ,our annual production
ability can achieved 20,000 square meters per day . We can produce
a large range of various filter fabric, such as polyester filter
fabric, Acrylic filter fabric, Fiberglass filter fabric, PPS filter
fabric, Nomex ,P84 ,PTFE ,woven filter fabric and so on.
The most important thing is that we introduced German high
technology to develop the first filter bag production line in
China. Which help most filter bag production factory save a lot of
human lab our cost but promote the work effection . The advanced
technology and simple operation way of automatic filter bag
production line has won a lot of customer’s praise.
