Designed for general air filtration applications with light to medium dust loading conditions, HeavyDuty™ 1" disposable panel filters are engineered for sturdy, economical performance and ease of use. The expanded metal support and skin provide excellent, corrosion-resistant support for the fiberglass. The heavier construction of the fiberglass allows a better adhesive bond with the expanded metal grid for superior strength and durability. Compression resistant glass fibers decrease media pad deterioration, extending the life of the filter. Available in a wide range of sizes, HeavyDuty™ panel filters are used in all types of HVAC systems to protect the coils from dirt. They are also used as prefilters to extend the life of higher efficiency filters.
