All units have a capacity for a population equivalent of up to 10 persons. *Comparison based on full floor coverage at 8 lb O. Main Components in Blower System. The basic unit of air diffusion type aeration devices is the air compressor which can be a root-type blower, a ventilator, a compressor or a membrane pump. BLOWERS - Provided in multiple units for varying the volume of air delivered in proportion to the load demand of plant and arranged in such capacity as to meet the maximum air demand with the single largest unit out of service. Conventional blowers generate piping noise & destructive pulsations Pressurized air in discharge is about to return into blower housing System pressure (dark blue) Abrupt pressure equilization causes sound wave and shock Atmospheric pressure (light blue).
