Air Handling Unit Filters

The Interfold is suitable for air conditioning and industrial applications. The Interfold is a compact and economical air filter that features low operating costs along with high dust holding capacity. The Interfold is totally disposable. A simple retro-fit can upgrade any new or existing air filtration system to incorporate an Interfold. The high dust holding capacity extends replacement intervals, and used as a prefilter, considerably lengthens the service life of other secondary filters in the system. 

The achievement of indoor air quality is a function of system design, filtration selection and maintenance as described in Australian Standard AS3666. Contaminated heating and cooling coils have heating/cooling transfer efficiency reductions of up to 25% when a coating of 1mm of dust is collected on the coil surface.
