Transflow / Crossflow blowers are suitable for refrigeration, food service, electric heat applications, fireplaces, gas and wood burning stoves. DC motors offers greater versatility for differing speeds and variable speed control requirements. Magnetic fields produced by high-strength permanent magnets require no electrical current from the motor’s power supply, improving the motor’s energy efficiency and internal heating. This current draw enhances the life of batteries used as power supplies in mobile and remote electric motor dc applications.
