Air pre-filters are commonly used in various HVAC (Heating, Ventilation, and Air Conditioning) systems to improve indoor air quality.
They are typically installed as the first line of defense in the filtration process, designed to capture larger particles such as dust, pollen, and pet dander, before they reach more advanced filtration systems, protecting the more delicate and expensive filters downstream.
Air pre-filters extend the lifespan of primary filters and enhance overall air filtration efficiency.
Mainly used in HVAC systems
· Paint booth facilities: traping overspray and large paint particles
· Manufacturing: safeguards equipment and machinery
· Cleanrooms: pharmaceuticals, electronics, and healthcare
· Automotive facilities: protecting sensitive equipment
