Pipe And Blower Fan Fundamentals In ASP Design
Facilities can test various piping system designs, such as entrenching the pipes as shown in this pilot test (top). ASP composting designs most often use centrifugal blowers (bottom), as these are recommended for systems with back pressure caused by having long runs of piping or ducting
