EHF series
EHF series filter element is a large diameter, no center rod, single opening, and with a unique flow in and out of the filter element. Super flow reduces the usage of filter element and filter. A variety of filter film materials are available to suit different application requirements.
Product Features:
Large filtration area and high flux
With unique folding technology, the filtering area can reach 3.2㎡/20 inch.
The 40-inch large-flow filter element has a flow rate of more than 60m /h under standard conditions. High throughput and long life.
Multiple choice of film materials
PP and PTFE films are available. PP membrane material adopts unique multi-layer Nano-fiber folding technology to achieve gradient filtration structure, increase pollution carrying space, greatly prolong service life, thus reducing replacement frequency and system cost.
Multiple length selection
There are 20", 40" and 60" lengths available.
