Why doesn’t MBA use a 1 horsepower motor on their dust collectors like the other manufacturers?
Unlike many other manufacturers who use an off the shelf blower assembly which must operate alone, MBA designs and builds its own exhaust blowers. This allows MBA to consider the motor horsepower taking into account the total machine running or operating static pressure. Static pressure, or resistance of the air to flow, prevents some air from getting to the blower during operation. Since MBA’s blowers are not off the shelf blowers this allows MBA to use smaller motors. If the blower were operating on a bench with no static resistance from the machine the motor would need to be larger. Therefore, fractional sized motors can be used which creates an additional benefit of not having to hardwire most MBA cabinets. If you require single power source electrical or larger exhaust blowers, MBA offers as an option.
