50-500Pa Adjustable Air Pressure Switch for HVAC Ventilation Air Flow Control

This switch is able to feel a small change in pressure and is often used to control the aerator, monitoring and fan as well as air conditioning. It is also suitable for overheating protection and frost protection in industrial cooling systems. Due to its exceptional properties, the set value can be adjusted visually. This pressure switch is mainly used in ventilation and air conditioning systems to control the flow of air in air channels, as well as in filters, fins and fans. They are suitable for air and other non-flammable and non-aggressive gases. Operating temperature: -22°F to 185°F (over pressure 5000Pa). Wide application for HVAC systems, fans, fans and overheating/freezing protection in industrial cooling. High sensitivity pressure measurement detects tiny pressure changes for precise device control.
