Protective ventilated products are widely used in various industries: automatic engine and system, LED, electronics, portable electronic products, photovoltaic new energy, outdoor equipment cabinet, chemical packaging, battery and so on. With years efforts, Voir protective technological vents successfully won clients' trust domestic and overseas.

Solution

■Protective solution provided by Voir
Specification on Voirs Protective Vent To protect the sealed but not vacuum components, like automobile’s battery pack/ box, Voir has developed EPV protective vents that not only help to rapidly release the pressure but also resist explosion/ water/ dust/ oil. Normally, it helps the enclosure to breath; but when the pressure reaches the critical point,it breaks the membrane to release a large number of air, by this way it releases the great pressure of the inside and prevents explosion from happening or lower the damage from explosion.
Reliability Requirement:
>>Service life being more than 10 years
>>Protective rate can still be IP67 after service life span test
■ The Performance of the Protective Vent(When the Inner Pressure of the Automobile Battery Reached 80Kpa, Alarm will get to work immediately to prevent explosion)

Peculiarity

>> Balancing pressure (pressure from inner and outer battery)
>> Releasing pressure (it can rapidly vent the gas after the cell abnormally exhausts, preventing damage to the battery or other components from excessive pressure)
>>Battery can be tested the air tightness by installing onto holder
 

Installation

Advantage

>>Extend the Normal Working Time 
>>Lower Cost For Maintenance  
>>Small Space Needed for the Vent
>>Better Structure 
>>Technology Upgrade
