Model FC-BHBS

Single Inlet-Belt Drive

Performance Characteristics

  • In these systems, the connection between the impeller and the electric motor is indirect and belt-driven.
  • The design of these types of fans is based on the impeller method, with the impeller positioned between two bearings (Impeller Between Bearing) and also overhung (Impeller Overhung), in accordance with the AMCA standard.
  • The airflow capacity can reach up to approximately 40,000 cubic meters per hour.
  • The static pressure can reach up to approximately 18,000 pascals.
  • The diameter of the fan impeller can range up to 1250 millimeters.
  • The inlet airflow volume can be adjusted using dampers or by changing the speed frequency.
  • These series of fans can operate effectively within a temperature range of -40 to 500 degrees Celsius.
  • The positioning of the outlet nozzle relative to the inlet and its angle concerning the horizon can be selected according to the AMCA standard.
  • These air handlers can accommodate various accessories such as dampers, silencers, bird screens, and chassis.
  • These fans are primarily used in gas and polluted air collection and transfer systems.
  • Based on the performance capacity and efficiency of the fan, the blades of these fans can be designed as backward curved or backward inclined.
  • The vibration balance of these fans conforms to the ISO standard DIN ISO 1940-1 grade G 6.3 <4 mm/s.

Special Design Methods

  • In environments with high corrosion and acidity, stainless steel 304 or stainless steel 316 materials are used for the body and impeller of the fans (stainless-steel fans).
  • In the presence of flammable gases and dust in the environment where the fan is located, to prevent sparks and explosions, the fan is completely isolated from the surrounding environment. Additionally, a layer of copper or composite insulation is used on the potential collision area between the two metal components of the impeller and fan body (Explosion & Spark-proof Fans).
  • In the oil, gas, and petrochemical industries, centrifugal fans are designed and manufactured according to the international standards of oil API 560 & API 673.
