Description
The Cleveland Controls DFS-448-153 Air Flow Switch Positive is used in measuring airflow in HVAC systems including air handlers, fan coils, and rooftop units. The method is based on the change of pressure or velocity of the air streams. Depending on the level of airflow, the switch either sounds an alarm or stops the equipment to avoid damage or low efficiency. This aids in achieving the better results out of the system, makes the system energy efficient, and increases safety by avoiding cases of overheating or equipment breakdowns. Advantages of Cleveland Controls Air Flow Switch Positive include the ability to detect airflow issues early, increased equipment reliability, low energy usage, increased safety, and ease of maintenance.
