Air Filter Testing

The air filter is a device that captures dust from the gas-solid two-phase flow through the action of porous filter materials and purifies the gas. It purifies air with low dust content and sends it indoors to ensure the process requirements of clean rooms and the air cleanliness in general air-conditioned rooms. There are primary-efficiency filters, medium-efficiency filters, high-efficiency filters and sub-efficiency filters. Various models have different standards and performance capabilities.

Air filter testing is a type of inspection aimed at assessing the condition and efficiency of an air filter, typically found in HVAC systems, cars, or other machinery where air cleanliness is crucial. The process usually involves checking for accumulations of dust and debris, inspecting for damages like holes or tears, determining the level of particle filtration, and sometimes even monitoring airflow rates. There are various testing methods used including gravimetric analysis, particle counting techniques, and differential pressure measurement.

STEMart provides comprehensive and reliable air filter testing services to ensure that an air filter is functioning optimally, capturing the necessary pollutants while still allowing adequate airflow.
