The VariCel filter is a high capacity, extended surface, supported pleat filter engineered for a variety of applications. With a supported pleat media pack, the VariCel filter’s rigid construction maintains a compact, unitized structure even under difficult operation conditions, such as variable air volume, turbulent airflow, repeated fan shutdown, high temperature operation, high humidity, or intermittent exposure to water, such as seacoast instillation. Variable air velocity and repeated fan shutdown do not compromise performance.
