High-efficiency Filter Test Bench

Introduction

The high-efficiency filter scanning test bench can test the efficiency and resistance of filters under the rated air volume conditions. The fundamental core of the test bench is particle counting. The dust source used in the test bench is liquid aerosol (DEHS) with a certain concentration, with a particle size of 0.1-0.3 μ m.

Meet the standards

It is designed and manufactured in accordance with the principles and requirements of the European standard EN1822-5 and in reference to relevant standards.
