General information

• low Pressure
• One-side suction
• Number of blades – 16
Fans of ВО30-160 type are designated for antismoke ventilation; they areinstalled in the special air-supply  and  smoke-exhaust  systems  for  generation of  an  excess  pressure  in  stairway  enclosures, entries,  gateways  and  elevators’  wells  of  the  buildings  in  order  to  prevent  smoke  ingress  into  these premises  and  provide  a  possibility  to  perform  activities  on  fire-fighting  and  rescue  of  people  and equipment
Impeller  is  manufactured  with  a  big  relative  diameter  of  a  hub,  constituting  70 %  of  impeller diameter. Possibility of mounting the blades at different angles is considered to be a specific feature of these  fans;  owing  to  this  fan  with  one  diameter  of  impeller  provides  a  range  of  different  modes. Straightener  blade  and  built-in  baffle  ensure  reduction  of flow  speed  at  output  section  of the fan  anddynamic pressure, providing simultaneous increase of a static pressure.
Fan ВО30-160 is manufactured in 2 layouts, which are different by a way of shell mounting: flange mounting (layout 1) and mounting on a frame (layout2).
Fans  must  be  mounted  out  of  attended  premises  and  beyond  the  area  where  people  stay permanently.  They  are  designated  for  operation  in  the  conditions  of  moderate  (У)  and  tropical  (Т) climates of the 3rdcategory of location.
• Ambient temperature: -40 to +45°С (-10 to +50°С for fans designated for tropical climate).
• In ordinary conditions transferred medium shouldnot contain adhesive substances, fibrous materials, steam or dust, have an aggressiveness towards carbon steels higher than air aggressiveness; content ofdust and other solid admixtures should be more than 100 mg/m3.
• Average value of vibration velocity for external vibration sources in the places of fans’ mounting– not more than 2 mm/sec.
