ESPA2 is the diaphragm with the highest desalination rate in ESPA series. Different types of products are made by rolling this diaphragm, which has the characteristics of high desalination rate and better energy saving effect. ESPA2 comes in 4 "and 8" sizes.

The membrane area of espa2-7 membrane element is 400 ft2 (37.2m2), and the membrane quantity can be saved by about 10% when using the same water flux design. Espa2-7 is commonly used in ultra-pure water systems or secondary RO systems. Espa2-7 is an 8-inch membrane element.

Espa2-7 is a new type of membrane element which adopts the innovative diaphragm technology of headneng company and combines the large membrane area and the wide water inlet barrier network 34mil. At the same time, it has the characteristics of large membrane area reducing the use of membrane, and has anti-pollution and blocking performance, suitable for large municipal, semiconductor industry and other applications
