VariCel II


Designed for high performance under both normal and difficult operating conditions, VariCel II is appropriate for general HVAC and applications operating with variable air volume, turbulent airflow, and high humidity. The combination of durable construction and high efficiency also makes VariCel II ideal for specialized systems such as diffusion filters in paint booths and prefilters in cleanrooms.

VariCel II’s slim line design provides minimum resistance with the high dust loading capacity of larger, traditional filters. The pleated media is made of microglass paper with a dual density fiber construction and water repellent binder . Two die cut boxes form a sealed, double wall around the perimeter of the filter. Media pack support retainers and adhesive pleat separators are bonded and applied to the pleats. Together, these form a unitized, rigid media pack that maintains pleat spacing and a maximum, even distribution of airflow.

The thinner depth and fiber board frame make handling, storage, and installation the easiest of any high efficiency filter. Disposal is also simplified from the absence of metal components.

VariCel II Ultra filters with EPA-approved antimicrobial are engineered to improve Indoor Air Quality (IAQ). Antimicrobial inhibits the growth of microorganisms while preserving the integrity of the filter media.
