A filter assembly for removing particulate contaminants and chemical contaminants from an incoming dirty air stream for a fuel cell. The filter assembly also includes a noise suppression element that reduces sound waves or noise emanating from any equipment, such as a compressor. The filter assembly can include a particulate filter portion for removing physical or particulate contaminants, a chemical filter portion for removing chemical contaminants, or can have both portions.

Filter assemblies and systems for intake air for fuel cells

An early warning system for equipment or processes which can be permanently or temporarily damaged by contaminants coming from air moving equipment, such as a compressor, positioned upstream of air flowing through the equipment. The present invention provides a seal-leak detection arrangement that, when incorporated into air moving equipment, monitors the air passing through the air moving equipment for the presence of contaminants such as lubricant oil, which could damage the equipment downstream. At least one sensor is positioned downstream of a contaminant retaining seal within the air moving equipment. The seal-leak detection arrangement is particular useful when incorporated into systems upstream of a fuel cell.

Filter assembly for intake air of fuel cell

A system for detecting fires in a barn or similar structure includes rate of rise heat detectors and temperature sensing cable. Upon detection of a predetermined rate of rise or a predetermined temperature the control circuitry of the system produces an output signal that activates an audible alarm mounted outside the barn. The control circuitry also produces an FM signal that travels through the power lines servicing the farm. The FM signal activates an audible alarm plugged into an electrical outlet in the home.
