500L/min Large Inhalation Respirators Breathing Resistance Test Machine

Large Volume Respirator Breathing Resistance Tester

MODEL: SM-4309B

The Large volume mask respirator breathing resistance tester is used to measure the inhalation and exhalation resistance of respirators under specified conditions.

Wear the test sample on the matching head mold in an airtight manner, adjust the ventilation capacity to 30L/min and 95L/min, measure and record the maximum suction resistance, and then test the expiratory valve with a large ventilation capacity of 300L/min for 30s;

SM-4309B tester is equipped with a large flow air pump with adjustable flow rate, two sets of pipeline systems for inhalation and exhalation, flow sensor and other respiratory resistance measuring devices; The system can automatically control the ventilation and measure the inhalation and exhalation resistance.

Testing Scope:

Protective half masks, etc.
