145mm, 12–48 V, 100–120 V or 220–240 V, ≤1900W
The 491 series of vacuum motors includes tangential bypass motors for wet and dry applications.
The 491 series motors have a robust skeletal structure and a diameter of 145 mm. They are available in one-, two- or three-stage configurations. These motors are the most efficient in their performance and size category. Their eco-friendliness and energy efficiency are further expanded by their aluminium structure, with additional bearing protection for reliable and silent operation in severe conditions. Due to extremely high negative or positive pressure, the 491 series motors can be used in various appliances, particularly central vacuum cleaners, commercial/industrial vacuum cleaners and blowers.
The 491 series vacuum cleaner motors are designed and manufactured in the EU.
