Combustion wind wheel impeller for 5KW Coolant Heater

Combustion wind wheel impeller for 5kw water heater

Due to product upgrades, we not use PPS now，and we replaced the 5KW combustion wind wheel with better quality PEI materials, with better high temperature resistance and better stability, avoid thermal expansion and contraction, will not jam the fan, the quality is exactly the same as the German quality，so the price is high. 
 
If you use requires PPS material now, and we let material factory processing, the MOQ is 500~1000, now we all changed into PEI materials for better high temperature resistance and better stability
