General information

• low Pressure

• One-side suction

• Number of blades – №3,15; 4; 8 – 3; №5; 10 – 4; №6,3; 12,5 – 5

Fans of ВО 14-320 type are made of carbon steel and designated for displacement of nonaggressive gas-and-air mixtures, having temperatureof not more than 50° Сand level of dust and other solid admixtures of not more than 10mg/m3, which do not contain adhesive substances and fibrous materials.

Fans ВО 14-320 В (explosion-protected fans made of mixed metals) are designated for displacement of gas-steam-air explosive mixtures of IIA and IIB categories, which do not cause accelerated corrosion of carbon steel and aluminum (rate of corrosion – not more than 0,1 mm a year), wherein content of dust and other solid admixtures does not exceed 0,01 g/m3, and there are no adhesive substances and fibrous materials

Fans ВО 14-320 В are not applied for displacement of gas-dust-air mixtures from the process units, in which explosive substances are heated above the temperature of their spontaneous combustion or are exposed to an excess pressure.

Range of ВО14-320 fans’ application: ventilating systems in oil-and-gas processing, refrigerating and welding units; cooling tower; drying cabinets; coolers; air-supply and painting booths; ventilation of industrial objects, buildings, garages, basements, tunnels, service stations, etc.
