• 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.
