Air-lntake-Filter-Screen Technology Helps Optimize AHU Performance Keeps snow and airborne debris from damaging filters

摘要

At a major university in the Midwest, one of the main air-handling units (AHUs) serving a 65,737-sq-ft biomedical building was experiencing ongoing problems during winter: On one side of the building, snow drawn through the intake louver would accumulate on MERV 8 pre-filters until its weight and moisture caused the filters to collapse, exposing expensive MERV 15 bag filters relied upon to provide fine filtration.
