AIR FILTRATION MAINTENANCE

Engine air filter life is shortened by dirt, carbon soot and moisture. Transit buses operate in an environment where all these contaminants are prevalent. Soot is a major problem with paper filters, reducing their ability to hold dirt. Water is another important factor in reducing useful filter life. It is suggested that relocation of a bus air intake or exhaust may alleviate some of these problems. A reticulated foam is now available as a replacement for the paper medium used in filters. Both intercity and transit organizations have tested this filter; but builders are also now offering it. The design of any filter and its housing are important factors, along with the medium used. It is concluded that filters should be changed only when air flow restriction reaches the engine manufacturers' limits. Not only is too frequent changing unduly expensive but it also increases the possibility of letting contaminants into the engine.
