New Tech Optimizes Air Filters and Can Cut Energy Bills
In the past, Facility and Plant Managers scheduled filter replacements based on time in service, a visual inspection of the filter media, or measured pressure drop across the filter bank.Those days, thankfully, are behind us.
Historically, inspections of a facility's air filters were visual and, therefore, open to human error. As a result, filters either were replaced too soon, increasing filter costs, or too late, reducing air flow and increasing fan-energy requirements in variable-volume systems.
Getting the metrics around pressure drop across the air filter bank was reliable in constant-volume systems. but, in big corporate variable-volume systems or systems equipped with variable-frequency drives, constantly changing fan speed to match airflow to building requirements results in constantly changing measured pressure drops across the filter bank.
Innovative air filter technology is helping maintenance and engineering managers determine the best time to replace existing air filters with the effect of saving $1000s on annual energy bills.
CleanAlert's award-winning new-generation monitoring tools compensate for changes in fan speed providing a more accurate assessment of the filter’s condition.
