The 900 series of “H” specification machines has been specifically designed to meet the requirements of industries where it is necessary to remove dust that could constitute a health hazard. The power head is of all-steel construction and is available in a choice of one or two motor construction. Power and performance are to full Twinflo’ standards and plugged easily replaceable cable systems are a standard fitment. The HEPA filter units are securely mounted on their steel module with separate primary pre-filter mounted within the main container and the machines are designed to use our giant Microflo’ dust bags to ensure easy, clean and safe emptying. This machine is available with a Simplex single motor power-head (HZ 900) and 32mm kit or a Duplex twin motor power-head (HZD 900) and a 38mm kit.
