* The B500 is an entry vacuum blower designed to be used with a 3” plumbed system with a maximum recommended operation of 2400 RPM. At 2400 RPM it is capable of 431 CFM free air, 80% efficient, and able to generate 24” HG corrected to sea level. It is able to run at maximum vacuum with no vacuum relief valve required. The B500 silencing system is able to limit exhaust noise and should require no additional silencing to yield acceptable acoustic performance. Because the B500 is an entry level machine designed to be used with 3” plumbing, it is not recommended for the machine be operated at a higher RPM.
