Warranty

Safety

Envira-North's blade toppers prevent a rotor from falling or a blade from coming off even in the unlikely event of a catastrophic failure of the hub or drive system. The collet-type friction drive bushing connecting the hub to the reducer shaft allows controlled slippage in the event of a seizure of the reducer mechanism, or a failure of the soft start feature in the control panel.
