Intelligent Differential Pressure Controller with Real-time Monitoring for Automatic and Manual Fresh Air Ventilation

Product Overview:

The LCD digital display intelligent fresh air controller KF-500C-YC supports both manual and automatic operation modes. It automatically adjusts the blower's activation and speed based on real-time indoor-outdoor pressure differentials.

Supporting both automatic and manual control modes, the controller ensures accurate pressure regulation in critical environments such as hospitals, clean rooms, laboratories, commercial buildings, and industrial facilities. It helps prevent polluted air infiltration, improves indoor air quality, and creates a safer, cleaner, and more comfortable environment.
