Our metal washable air filters are permanent pre-filtration options for commercial and industrial HVAC systems. Common outdoor applications include outside and make-up air intake units and return-air units or “RTU”. Roof top economizer hoods utilize these metal mesh pre-filters as economizer screens to protect equipment.
The primary function of the economizer filter is to remove large airborne contaminants and coolant mist from the air stream. Our filters offer durable, multi-layered construction, low airflow resistance and are all washable and reusable.
