Quantifit Respirator Fit Tester

08 July 2019

Exclusively available from Shawcity in the UK, this is the industry breakthrough in mask-fit technology.

The fastest fit-tester available, it utilises simple air and controlled negative pressure to directly measure respirator leakage and unlike other technologies does not require consumables such as alcohol solutions, wicks and probes. It can also be used in any environment - indoor/outdoor, clean/dirty - as long as air is present, so no longer any need for lighted candles, blowing salt fog or filtration systems.

During a fit test, the respirator inlets are capped with test adapters, and the inhalation valves are propped open or removed from the mask. With the test subject holding their breath for no more than ten seconds, the Quantifit then establishes and maintains a slight vacuum, or controlled negative pressure, inside the mask.

Since the respirator inlets are sealed, all sources of leakage into the mask are through the face-to-facepiece seal or due to integrity issues. The volume of air drawn out of the mask by the Quantifit during this short period of time is equal to the leak rate into the mask through the face-to-facepiece seal.

Easy-to-use, simple operation means many users can self-test once trained. A fast and easy fit method with very quiet operational noise. Fit is measured by simulating movements approximating real life.

Fit testing for: Quantitative respirator (QNFT), half masks, full-face, gas mask, PAPR and SCBA.
