What is the air filter assembly and what does it do

An air filter assembly with a flow rate of 400 liters per minute is a device used to filter and purify the air. It removes unwanted particles, such as dust, pollen, and other contaminants, from the air to improve its quality. The flow rate of 400 liters per minute refers to the volume of air that can pass through the filter in one minute. The specific details of an air filter assembly with this flow rate would depend on the design and specifications of the particular product.
An air filter assembly is a component in an internal combustion engine, or in an HVAC system, that cleans and filters air before it enters the engine or ventilation system. Its main function is to remove particulate matter, such as dust, dirt, and pollen, from the air to prevent contamination of engine components and to improve indoor air quality. An air filter helps to protect the engine by preventing wear and tear on its internal parts, increasing its lifespan and improving its performance.
