Leakage test system Inward Leakage Testing System

Model: RF4310U

The leak test system is used to simulate the ratio of the concentration of the simulated agent that leaked into the mask when the subject inhales to the simulated agent concentration in the test environment outside the respirator mask under the specified laboratory test environment. It can also be used for leak test of protective clothing.

The total leakage rate (Total Inward Leakage TIL) refers to the ratio of the concentration of the simulant that leaks into the mask from all mask parts including the filter element when the subject inhales to the simulant concentration in the test environment outside the respirator mask.

The leak rate (Inward Leakage IL) refers to the ratio of the concentration of the simulant that leaks into the mask from all parts of the mask except the filter element when the subject inhales to the simulant concentration in the test environment outside the respirator mask.

Scope of application: Medical protective masks, disposable respirators, half mask respirators, full face mask respirators, protective clothing, etc.
