Common Air Filter

Liquid filter material quality can be mainly divided into two types:including PP and PES.there are two forms of supply coil and sheet.Product quality is in line with YY0770.1-2009 medical infusion filtration materials-part 1: liquid filter material standard request,and with third-party medical device testing organizations test report issued by qualified

PES as the new filter material,han been widely used in foreign countries,foreign precision liquid filter generally used as a liquid filter material PES.PES liquid filter material has many advantages:

opening rate,liquid flow rate is hign

Aperture can be 0.22µm-5µm,and with hign filtration precusion,and idealfilter effect

Has a stromg chenical stability,acid and alkali

Liquid adsorption low

Byphase inversion method molding process,the materialitself is not falling,there is no self-pollution risk in clinucal transfusion.

2PES electron micrograph(cross-sectional view),you can directly seen the internal structure and pore size distribution of the material in Fig

3PES electron micrograph(surface map),you can directly seen the hign open porosity of the mate-rial figure,while reflecting the pore size distribution of the material surface
