空气滤清器滤纸对燃气轮机的使用寿命至关重要．所选滤纸要高效；捕集效率要高；透气度要适中；与燃机所需进气量要匹配；初阻、终阻要小．积尘后压损上升要还慢，强度要大；寿命要长；防水性能要好；费用要低．
Air filter The filter paper is vital to the life of the gas turbine. Select the filter to be efficient; capture efficiency to be high; air permeability to moderate; and intake required to match the gas turbine; initial resistance, the final resistance to be small. Dust after the loss of pressure rise to slow, strength should be large; longer life expectancy; waterproof performance is better; the cost is lower.
