Prefilter Efficiency Improvement

• Filter Coat Adhesive

Aprilaire 412 Super Filter Coat increases efficiency and dust holding capacity of prefilters used in electronic air cleaners.

The Super Coat adhesive have a unique viscosity oil in a gel-like structure. This viscosity oil constantly absorbs dirt particles. As particles are trapped, they recede into the interior of the adhesive, and through the circulation of the low viscosity oil a renewed impurity absorbing surface is established. This action provides a continuous impurity absorbing surface layer.

The aluminum mesh prefilters will maintain their initial efficiency with periodic applications of RP Super Filter Coat after cleaning. After a period of use of the prefilter, dirt, lint and the original water soluble adhesive coating are easily removed by simply flushing the filter in a stream of water. A new, easily-applied coating of RP Super Filter Coat can restores the filter's superior performance qualities.
