Model 85A Transformer Fan Control

Square-D Life-Gard fan control systems were released in the early 1990s by the Square D Company and have been long considered the industry standard. The Model 80, 85 and 85A systems were dependable fan controllers that regulated temperature, keeping industrial electrical systems operating smoothly. They are commonly used in residential and commercial HVAC systems.

These fan control systems are a critical component that protects your transformer and increases reserve capacity. The Model 85A Transformer Fan Control typically uses a step-down transformer to reduce the voltage from the AC power source and supply a lower voltage to the fan motor. By adjusting the voltage supplied to the motor, the control unit can regulate the speed of the fan and maintain a consistent airflow and temperature within the HVAC system.

System failure can result in a power outage, causing unexpected downtime that can impact your bottom line. As new technology emerged, these systems became obsolete. The original manufacturer no longer repairs or replaces the Square-D Life-Gard systems. Fortunately, these systems are by no means at the end of their lifespan and are fully capable of continuing to work effectively for years to come. Let our expert technicians who have 30+ years of experience, on average, complete your repair and get your equipment back up and running.
