Abstract: A filter assembly comprising a housing having an air inlet and an air outlet and a filter chamber disposed between the inlet and the outlet, the housing having an air flow path there through. A filter element having a first surface area maybe located within the filter chamber and oriented such that the first surface area is angled with respect to the air flow path. The filter element may comprise a filter media adapted to remove contaminants from the air. A drain may be associated with the housing and adapted to remove contaminants filtered out of the air.

Abstract: According to the embodiments of the Eldridge ENJET—Engine Exhaust Jet Nozzle invention, the method and apparatus include an external plenum, support spool, fan, and nozzle assembly that is sleeved over and mounted at the discharge end of an internal combustion engine exhaust silencer or pipe for the purpose of creating a high volume and high velocity discharge capable of overcoming prevailing wind velocity to such an extent that a cylindrical air discharge pattern 50-100 feet away from the end of the apparatus nozzle provides increased dispersal and dilution of the engine exhaust gas. The invention is especially useful for accelerating the high temperature, low velocity, and toxic internal combustion engine exhaust gas away from human habitation or work areas.

Abstract: A system for manipulating engine exhaust gases away from inhabited areas comprises an air pressurization system coupled in fluid communication to a housing. The housing is adapted to reside adjacent a terminal portion of an exhaust pipe so that pressurized air injected into the housing entrains the exhaust gases and disperses them from the housing.
