What is an air filter and what does it do?

An air filter is a device that captures dust from a gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It is mainly used for dust prevention in clean workshops, clean plants, laboratories and clean rooms, as well as electronic mechanical communication equipment. There are many types of air filters, including primary filters, medium filters, high-efficiency filters, sub-high-efficiency filters and high-efficiency filters, each with different standards and performance.

Working principle of air filter

The working principle of air filter is to filter dust and particulate matter in the air through porous filter materials. When air passes through the filter, dust is captured by the filter material, while clean air continues to flow through the filter. Different types of air filters have different working principles:

‌Inertial air filter ‌: Using the principle that the density of impurities is greater than the density of air, impurities are separated by rotation or sharp turns.

‌Filter air filter ‌: Impurities are blocked by metal filter or filter paper.

‌Oil bath air filter‌: Use the rapid turn of airflow to impact the engine oil, separate the impurities and stick them in the engine oil‌.

The role of air filter

Improve work efficiency‌: Reduce failures caused by impurities and improve work efficiency.

Protect equipment‌: The air filter can filter out dust and particulate matter in the air, reduce the wear of cylinders and pistons, and extend the service life of equipment.

Maintain a clean environment‌: In clean workshops and laboratories, air filters can maintain the cleanliness of the environment and meet specific process requirements‌.

Application scenarios of air filters

‌Electronic mechanical communication equipment‌: Prevent dust from entering electronic equipment and communication equipment to protect the normal operation of equipment.

Laboratory‌: In the fields of scientific research and medical care, maintain the cleanliness of the laboratory and ensure the accuracy of experimental results.

Industrial production‌: In the clean workshops and clean workshops of the factory, ensure the cleanliness of the production environment.
