This mini-duct hvac system manufacturer says all its blower module motors are now located in the center, directly in the air stream. Mounted using the company's "twist and lock" design, they say it makes service work easier for the contractor. If service is required on the motor or wheel, the entire assembly can be removed and need only be accessed from one side of the module. The blower motors also feature adjustable ventilation speed.
