thermal various types of outdoor electronic products,the cabinet often suffered from temperature change, wind and rain erosion and the sun's radiation, Environmental temperature fluctuations, can create pressure difference of equipment, constitutes a negative impact Shell Waterproof dustproof heat through valve help balance inside and outside pressure, preventing air front housing and water through the sealing strip into the cabinet interior, and can effectively protect the integrity of the seal. Breathable membrane can also accelerate out moisture vapor condensation, thus reduce speed,gives protection. Waterproof dustproof heat through valve can adjust pressure, thus avoid gas accumulation.Breathable membrane in this case the role of mechanical safety valve, equivalent and it also can play protective barriers, stop dust, salt and other corrosive liquid invasion, to extend product performance and life, reduce unnecessary maintenance and waste, the cost savings. Suitable for: household appliances, audio equipment communications equipment, sensors, outdoor lighting, large outdoor LED display, computer equipment, automobile exterior lighting, monitoring equipment, etc
