Introduction to Pre – Filter
Pre – filters are essential components in various filtration systems. They are designed to remove large particles, such as dust, pollen, and lint, from the air or liquid before it reaches the main filter. By capturing these larger contaminants, pre – filters extend the lifespan of the main filter, improve the overall efficiency of the filtration system, and reduce maintenance costs. They are widely used in industries like HVAC (Heating, Ventilation, and Air Conditioning), water treatment, and industrial manufacturing. Pre-Filter
