Specification


STRUCTURE 
 
High Flow string wound filter is patented in China by SF Filter. Using multi-holes to make the filter 9 times dirt holding capacity as ordinary string wound cartridges. With O-rings to avoid bypass. 3 grades are available. HFA, HFB and HFC can meet most pre-filtration requirements. 
The end cap and dimensions can be customized to meet certain requirments

FEATURES 
 
• High dirt holding capacity, long service life
• No bypass
• Easy replacement
• Through holes create real depth filtration

•  High flow rate and low pressure loss
•  Pure, clean and washed material which is same as NSF approved type (HFA). 
Pure material, suitable for strong corrosion liquids (HFB). 
• Common material, allows lower price (HFC).
