Mask Leak Testing Device

Protective Mask Leakage Tester

The PortaCount Respirator Fit Tester is a portable device designed to detect the service performance and applicability of protective masks, and provide leaks and service performance testing for specified nuclear, biological and chemical defense (NBCD) / chemical, biological and radiation defense (CBR-D) masks and components without the need for the operator to wear a mask.

Overall Mask Leakage Test : Mask leakage is measured while the mask is challenged with an aerosol, with or without a plugged filter canister attached.

Leakage Isolation Test: Leaks normally invisible to the naked eye are easily isolated so that repair/replacement decisions can be made.

Standards

GB2890-2019 "Respiratory Protective Equipment - Self-Priming Filter-Type Respirators": Specifies the test methods and indicators for the leakage rate of respirators;

GB16556-2007 "Self-Contained Open-Circuit Compressed Air Respirators": Specifies the testing requirements for the air tightness of respirator masks.

ISO16975-3:2015 (Test Methods for Respiratory Protective Equipment).

Applications

Wind exhaust Valve Test: In the wind exhaust valve test, suspended particles as a function in the mask test and isolation detect the airflow leakage under strictly controlled conditions.

Drink Tube Flow Test: Tube blockage can be measured.

Drink Tube Valve Leakage Test: The drink tube valve is tested for leakage under controlled pressure.
