Cleveland Controls DDP-109-186 Dual Pressure Switch

Cleveland Controls DDP-109-186 Dual Pressure Switch that is applied in HVAC systems to manage air or gas pressure. It is designed with two switches that are activated by two different pressure settings. This enables gradual control of HVAC equipment like starting a fan at one pressure and setting off an alarm or stopping the system at another. Advantages include increased system effectiveness through proper airflow, increased safety due to over or under pressurization, decreased energy use due to proper equipment control, and increased system dependability through pressure control.
