Prefilter Efficiency Improvement

RP Super Filter Adhesive Coat for Efficiency ImprovementAprilaire #412 RP 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 straucture. This viscosity oil constantly absorbs dirt particles. As particles are trapped, they recede into the interior of the adhesive, and throught the circulation of the low viscosity oil as 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.
