Air permeability tester for medical protective masks (Differential pressure)
This air permeability tester measures air permeability of textile fabrics such as clothing and industrial fabrics, technical, downproof, nonwovens, filters, paper, felts, tents, foam materials and other types.
- Precision volumetric counter for air flow measurements and pressure transducer with measure range up to 2500 Pa.
- HMI Touch screen with 5” crystal liquid display managed by the operator. Ultra-silent internal vacuum unit with sound pressure level < 40 dB.
- QUICK CHECK with flow meter reading on real time.
- Test area reduction flanges of 50, 20, 10, 5, 2 cm².
- Metal plate for periodical calibration check.
- Automatic pressure drop adjustment.
- ASCII Printer to get paper test reports.
- Application Software BAP4.0, for test monitor and statistical evaluations of results and trend analyse.
This kit measure the air permeability of protective medical masks according to EN14683:2019 and ASTM F2100:2019. The differential pressure kit is able to measure up to eight results in several points of the mask and doing at the end of the testing process an overall averaged sampling of the full mask surface and determining the specific air flow resistance of the air crossing.
