MASK FILTER TEST SYSTEM

摘要

The present invention relates to a gas mask filter test system. According to the gas mask filter test system, mixed air having specific test material particles is mixed with external dry air through a separate drying unit to dry the air into a dried state with reference relative humidity or less, thereby allowing the dried air to pass through a purifying filter that is an object to be tested. Thus, the gas mask filter test system may be adequate for testing filtering performance of the purifying filter mounted on the gas mask as well as improve accuracy in test result by smoothly supplying a specific test material during the testing. Since the external air is dried through a main dry module using a moisture absorbent to inject the dried air into a mixing chamber, thereby drying the mixed air having high relative humidity into a dried state with reference relative humidity or less, the drying unit may smoothly operate even though the drying unit is used for a long period of time. Thus, the gas mask filter test system may more stably perform the testing.
