Respiratory mask airtightness tester respirator as a respiratory protection equipment required in the field of medical protection, the type of mask can be mainly divided into disposable masks, replaceable half masks and full masks, the various properties of the mask for personal safety protection is also crucial, the air tightness effect of the mask will also directly affect the user's life and health, testing and evaluating the advantages and disadvantages of the airtightness of
the mask is very necessary.
Instrument use: for self-priming filter anti-particulate matter respirator airtightness performance test
.
Meet the standard: GB 2626-2019 respiratory protection Self-priming filter anti-particulate matter respirator 6.
7 Exhalation valve airtightness scope of application: can be tested according to customer requirements multi-station, negative pressure, positive pressure, airtightness tester, multi-station test can be customized according to customer requirements non-standard for self-priming filter anti-particulate breathing valve airtightness detection
.
Applicable to the Labor Safety Protection Inspection Center, Occupational Safety Inspection Center, Centers for Disease Control and Prevention, respirator manufacturers, etc
.
Principle: the mask is matched on the test head mold according to different specifications selection, seal the suction valve, wet the exhalation valve, start the vacuum pump, so that the mask internal pressure reaches -1000pa-1000pa, stop pumping, start timing, observe and record the pressure change value
in the mask.
Technical parameters: 1, the buffer capacity is not less than 5 liters 2, micro pressure difference metering range: -1000Pa ~ 1000Pa, accuracy 1%, resolution 1Pa3, vacuum pump pumping speed approx: 2L / min -30L / min according to the requirements can be arbitrarily customized 4, flow metering range: 0 ~ 100mL / min
.
According to the requirements can be arbitrarily customized 5, the overall size: 500×450×620mm according to the requirements can be arbitrarily customized 6, weight: 30kg7, power: AC220V 50Hz 150W
