Air Conditioning Filter Filtration Performance Tester

Instruction
The new air conditioning filter filtration performance tester uses positive pressure supply mode with high efficiency particle size spectrometer to quickly test the initial sample pressure drop, the end pressure drop, grading filtration efficiency and so on. It is the best choice to test the car air conditioning filter (Including dust or pollen, etc.) filtration performance. At the same time, the instrument is equipped with PM2.5 cyclone combination, used to test the car air conditioning filter PM2.5 filtration efficiency.
 
Application
Applicable to professional filter test
The air filter conditioning filtration performance tester is designed to evaluate the automotive air conditioning filter and also the pollen filter designed , which can test the Filter impurities by simulating outside dust air through the filter, such as tiny particulate, pollen, bacteria, industrial waste gas and dust, etc., to provide a good air environment for passengers in the car.
It provides the date basis on new filter material research and development, product quality control, material performance verification. It’s the best choice of scientific research, testing, industrial production and other areas.
 
Standards
1. GB/T 32085.1 Automobiles - Cabin air filter - Part 1:Test for particulate filtration
2. ISO/TS 11155-1 Road vehicles - Air filters for passenger compartments - Part 1: Test for particle filtration
3. DIN 714560.1 Road vehicles - Air filters for passenger compartments - Part 1: Test for particulate filtration
 
Significance & Principle 
As the air quality problem becomes more and more serious, the city road becomes a concentrated area of fine particles. The people who drive or ride will damage the respiratory system and even health due to fine particles, pollen, bacteria, industrial waste gas and dust.
Air conditioning filter, air conditioning activated carbon filter, air conditioning filter with HEPA filter papers and other filters can filter the fine particles, pollen, bacteria, industrial waste gas and dust with different degrees to provide relatively safe and healthy The breathing environment.
Due to the small size and relatively low concentration of fine particles, pollen, bacteria, industrial waste gas and dust, it not easily perceive. When the car staff feel inappropriate caused by air pollution  in the car, it only be found that the role of air conditioning filter is failing or no effect. Air conditioning filter filtration performance tester can quickly and accurately evaluate the effect of air filter element and filter assembly to provide the accurate data of manufacturer's product performance verification, product quality control. It also provides the using performance reference for the user, and become the effective means to regulate the market for technical supervision departments, improve market product control.
Dust dilution system can dilute the standard dust to the required particle distribution density. The air filter supply system provides positive pressure air to drag dust through the test sample. The upper and lower standard sampling tubes with particle size spectrometer and pressure gauge can rapidly detect the grading filtration efficiency, the initial pressure drop, the end pressure drop and other parameters.
