Two-speed fan at the top health nuisance exhaust system made use together is well known, type a lot of smoke and heat fire, and consume large amounts of air. On its harmful exhaust fan, staggering to smoke, smoke in his mouth many types of toxic factor, even if the non-toxic, also may be due to burning to make hypoxia suffocating to death.
