Important information and notice :

1 more information about design parameters ,you can read the UK new version of manual ,design direction and other relative data , or have a consultation with technologist .if user doesn’t obey the manual offered by us ,we will take no responsibility for what happen .

2 all the membranes are tested strictly and treated with 1.0% NAHSO3 for storage (propylene glycol antifreeze is added in winter ) before shipped .we adopt vacuum packaging and the hard cardboard is used for packaging . to prevent the UK growing of microbial in short term storage and transport . the protect liquid of 1.0% NAHSO3 is promoted (confected with ro pure water )to marinate components .

3.its suggested that the first hour of pure water be drained.

4.any chemical medicament ,having a bad effect on membranes performance .is bidden to add in the period of storage ,installation and normal function .when install ,please use pure water or glycerin if lube is needed .when clean ,refer to the clean method and the chemical medicament of complex offered by us .if you use other chemical medicament ,we will not take responsibility of what happened .

5.frp (fiberglass –reinforced plastic )is adopted for 4040 and the like 040 and the limited pressure is 15psi .adhesive tape wrap is adopted for household membrane .and pyrocondensation film is added for other dimension of membrane .

6.all the membrane produced by feyian adopt the universal standards of international size .and can interconvert with all types of membrane presently .25series adopt the pressure vessel whose diameter is 2.5inches ,40 series 4.0inches and 80 series 8.0inches .
