  • Escargot Air Filter designed for use with large industrial engines, such as diesel engines or electrical generators, integrates its plastic housing with the actual air filter of the unit. By molding the entire Escargot unit integrally, and by making it out of plastic, which requires no painting, a great savings in manufacture is realized. Self-contained and having no movable parts, Escargot is essentially a cartridge filter. When its life is exhausted, it is simply replaced. Escargot is not only named after the snail; it takes its functional clues from it as well. The air inlet — the opening of the snail and the point of entry into the filter — offers a very efficient way of distributing air into and through the filtering surfaces. While its appearance is the direct result of functional requirements, the snail-like configuration also operates at a higher level; it is emblematic of an in-out process during which a transformation takes place.
