A double inlet blower is a type of fan that uses two inlets to draw air through the fan. This type of blower is often used in industrial applications such as air-conditioning and heating systems, ventilation, and exhaust systems. The double inlet blower is designed to provide a higher volume of air flow than a single inlet blower, allowing the system to operate more efficiently. The two inlet design creates a higher pressure differential between the two sides of the fan, allowing for a greater volume of air to be moved. Additionally, double inlet blowers are typically more reliable than single inlet blowers since they are less likely to become blocked or clogged.
