Low noise centrifugal fan cabinet is to meet the growing current air conditioning, purification of industrial and environmental noise requirements in the digestion and absorption of foreign advanced technology premise, using the principle of aerodynamics and aeroacoustics wind combined with the new chassis, redesign of the successful development of new products. Wind volume, total pressure, low noise, vibration and other characteristics, in line with the requirements of environmental protection and labor protection. Low noise centrifugal fan cabinet is to meet the growing current air conditioning, purification of industrial and environmental noise requirements in the digestion and absorption of foreign advanced technology premise, using the principle of aerodynamics and aeroacoustics combining redesign successful development of new products. Wind volume, total pressure, low noise, vibration and other characteristics, in line with the environment of hazardous substances ... construction, decoration, furniture, decoration and office equipment is a major cause of the release of indoor pollution. Plus summer and winter people rely more on air conditioning cooling and indoor heating, indoor ventilation is poor, indoor harmful gas is not released and the replacement of harmful gases continue to accumulate, concentrations continuously increased, leading to the deterioration of indoor air quality, people feel sleepy, fatigue, chest tightness, susceptible to disease, reduced efficiency, which is the World Health Organization named the "sick building syndrome" also known as "Air conditioning disease" root cause of these difficulties is the lack of fresh air. Use fresh air ventilator replace indoor air, keep indoor air clean, can solve these problems. Therefore, the new wind ventilators is also a "health" products. Calling the situation as soon as possible following the popularity of ten new wind ventilators: 1, newly renovated house in the wind chassis, chemical gas against our bodies, we have to close the window every window; 2, even after years of residence, poisonous Gas still haunt our lives; 3, dusty room, mosquito bites and noise affect our rest and learning; 4, windows rain, dust, thieves, children make people worry; 5, water vapor accumulation clothing and valuables easily moldy damp; 6, cigarettes in the room, the kitchen fumes wind chassis models, toilet odor; 7, produced unventilated room as dark, no north-south entry window; 8, in a closed room air conditioner inside, tired exhaust chassis, headache, flushing, drowsiness, commonly known as the impact on people's health awareness, "Air conditioning disease" 9, SARS and other airborne diseases; 10, related laws and regulations such as indoor pollution control norms, a small central air fresh air requirements the introduction and enforcement of ventilation chassis _ Rich ventilation equipment (certified) _ wind chassis provided by Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (0) is the leader in Dezhou, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Rich ventilation equipment in leadership with the staff warmly welcome all inquiries negotiations to create rich, ventilation a better future.
