Simulated Wear Preprocessing Testing Machine

[Scope of Application]: The simulated wearing pre-processing machine is used to detect the simulated wearing pre-processing of respirators before conducting other tests such as respiratory resistance and filter material penetration

【 Compliant with standards 】:EN149/ 8.3.1

:

Simulate wearable pre-processing machine, consisting of respiratory simulator, test head model, saturated water vapor generation device, temperature control deviceComposed of flow meters and other components, the breathing simulator can be controlled to run at a rate of 25 breaths per minute, with each breath volume of 2L. The temperature of saturated water vapor near the mouth of the head mold can be controlled to be (37+2) °. Turn on the preprocessing device and put the breathing apparatus and saturated steam generator into operation until they reach stability. Wear the exhaler in an airtight manner on the matching test head mold and test for about 20 minutes. Remove the particulate filter material from the respirator, reinstall it, and repeat the test 10 times.

:

1Respiratory simulator respiratory rate: 25 times/min;
2. Simulated respiratory volume:2.0L/Stroke;
3. Flow meter range: 5-160L/min, 精度1 L /min;
4. The head mold tilts, and condensed water vapor flows to the collector;
5. Test head mold: 1.

6Power supply:AC 230V 50Hz

1Adjustable damping, no mechanical movable parts, high precision.

2Fully automatic measurement mode, no need to manually adjust the flow meter, high data reproducibility.

3Using a standard head mold, the mask sample is sealed and fixed to prevent air leakage, making testing convenient.
