99.97%~99.99% Filtrating Efficiency Surpass European Environmental Protection StandardAOF oil mist collector features higher air flow rate, temperature resistance as well as acid/alkali-resistance. Its filtrating efficiency many reach 99.97%~99.99%. In addition, an actual environmental protection compliance test indicates that it can reach E11. E12, surpassing the European standard of F8. F9. All these provide a proof that AOF oil mist collector is unique in efficiency and zero pollution.
