ARE VARIABLE SPEED MOTORS REQUIRED ON AIR CURTAINS?

The ability to adjust the outlet airflow is highly desirable; this significantly aids in the air curtain’s performance by allowing compensation for varying field conditions. Most Mars Air Curtains boast this feature provided through the adjustable air intake louver. Some models feature variable or multi-fixed speed motors while others include internal volume dampers in the air curtain’s discharge nozzle or a combination of the above. NSF certified models do not have any variable speed options. Please note, due to NSF regulations consult factory for specific model offerings.
