Baghouses Astec baghouses help assure efficient and environmentally sound operation of HMA plants. They provide the combustion air for the facility's burner, and filter the hot gas stream from the drying operation.
	Primary Collectors Astec stand-alone vertical and horizontal primary collectors are highly efficient and easily retrofitted to existing facilities or to replace old collectors. Horizontal collectors my be skid-mounted to make them portable and to eliminate the need for concrete foundations.
	Blue Smoke Systems Liquid asphalt cement, the "glue" used to hold the rock aggregate together in hot mix asphalt, is a petroleum by-product. At certain spots in the process, a haze of hydrocarbon droplets can escape.
	Sound Suppression Packages Expertly designed shielding devices minimize the sound level created by neighborhood asphalt facilities. Astec sound suppression equipment shields burner blowers, exhaust stacks, air compressors, and drum drives to reduce sound levels at the facility.
