Vari+Plus® - High Capacity Extended Surface Mini-Pleat Filters

When compared to traditional rigid or cartridge style filters, the Vari+Plus provides between 40% and 300% more filter surface area, assuring long service life and economical operation. The Vari+Plus is offered in four ASHRAE rated efficiencies -- 60-65%, 80-85%, 90-95% and 95%. This broad range of performance provides the required level of clean air for virtually any application.

The Vari+Plus is designed to handle large air flow volumes up to 3000 CFM per cell. In addition, the extremely low pressure drop, created by the high ratio of media to filter face area, results in significant energy savings and low operating costs. The leak free filter pack offers guaranteed removal efficiency with every unit produced. The filter is extremely strong and durable, yet light weight and easy to install. The pleat packs may be installed in the horizontal or vertical position. Burst pressure on the product exceeds 8.0" W.G. The Vari+Plus filters are constructed with microglass fiber paper media. The depth loading media is formed into mini-pleats which are separated by continuous beads of thermo-setting adhesive. This design maintains uniform spacing between the pleats to assure even air flow and media pack rigidity throughout the life of the filter. Each mini-pleat pack is sealed within the heat resistant plastic end panels and galvanized steel support struts. The entire media pack is guaranteed leak free around the entire perimeter of the product.

The construction of the Vari+Plus assures a rigid, durable air filter product. Installation into existing framework is quite simple, as the perimeter header is secured by standard latches or clamping devices. The Vari+Plus requires no rear support. It may also be inserted into side access housings with a 1" track.

The Vari+Plus is ideal for use in a wide range of installations. The product works extremely well in:
•(VAV) Systems Air Flow Systems
•High Volume Air Flow Systems
•Turbulence
•High Humidity Situations
•Hostile Environments
