Oskar Antipollution’s four-, five-, and six-inch diameter Vehicle Exhaust Hose Reels are designed to extract fumes and gases produced by heavy trucks and other machinery in repair and maintenance facilities. The company says the various lengths simplify the servicing of vehicles and help provide a safer workplace. The flexible hoses may be filtered with a variety of tailpipe nozzles and the outlet is designed to connect to a six-inch-diameter duct. Units come in a variety of standard production models, either with or without fans, and filters may be customized for a specific application.
