Centrifugal Blower Systems with MVP

Allegro centrifugal standard blower systems with MVPs are ideal for maintaining and redirecting airflow into tanks, manholes & sewers, with minimal restriction. They feature polyethylene construction to provide UV, chemical & corrosion resistance and safety orange colour for clarity in foggy or low-visibility environments. These blower systems come equipped with a molded-in carry handle for increased portability, and are available in 1/3 & 3/4 hp variants.

Working Mechanism

  • This centrifugal blower system operates by utilising centrifugal force to generate a flow of air or gas.
  • It consists of a rotating impeller within a housing, typically driven by an electric motor.
  • As the impeller spins, it creates a low-pressure zone at its centre, drawing in air or gas through an inlet.
  • The high-speed rotation of the impeller then expels the air or gas outward through an outlet, creating a continuous flow.
  • This mechanism is used in industrial settings to provide ventilation, remove contaminants, or maintain airflow in confined spaces, ensuring worker safety.

Features

  • These Allegro centrifugal blower systems feature polyethene construction for durability and chemical resistance.
  • They have vinyl / polyester ducts to provide flexibility and durability for ventilation and air quality control applications.
  • These blower systems are available in safety orange colour for clarity in low-visibility or foggy environments.
  • They come equipped with a molded-in carry handle for increased portability.
