Aerocompact offers two types of ballasted mounting systems for flat roofs. The Aercompact + is east/west oriented, whereas the Aercompact S is south facing. Both systems, the Aerocompact S and Aerocompact+, are designed so no roof penetration is required, both come with ballast trays for additional ballast, and both are backed by a 25 year limited product warranty. Aercompact systems allow for the quickest installation time in the industry. Reduced labor and material costs, as well as ease of installation make Aerocompact a much desired racking solution.
