负压百叶风机系列产品均采用CAD/CAM设计，具有投资少、通风降温效果显著，噪音低、风量大、耗能小、运行平稳、寿命长、效率高的特点，并拥有百叶自动开启、关闭系统。达到防尘、防水、美观等效果，是现代化厂房降温通风的最佳选择。
通过负压通风，使室内与室外空气交换，将厂内热气、异味完全排出厂外，原厂内空气排出后，由于负压作用，自然流入新鲜空气，使室内温度可降低至与室外温度相同。
风机根据厂房实际情况，计算每小时所需的换气次数、换气量、进行优化配置，有效解决高温闷热、空气混浊等实际问题。
Subpressure Fan series products are design by CAD / CAM,They have following characteristics : low investment, significant ventilation and cooling effect, low noise, big air volume, small energy, smooth operation and long life, high efficiency, automatically opened and closed system. They also have dustproof, waterproof, aesthetics effects, etc.They are the modernization factory best choice to ventilation ,cooling.
?Through subpressure ventilation make indoor and outdoor air exchange, the factory will vent the heat smell and off-flavor completely from the plant. After the air vent from the factory, because of negative pressure. Naturally it will flow fresh air to indoor,Indoor’s temperature can be reduced to the same with the outdoor temperature .
Fans according to actual plant conditions, calculated per hour for the number and volume of change air, , and optimize the allocation ,They are effective to solve the practical problem of ?sultry heat, air turbidity ?etc.

保养方法 / Maintain Technique
1、机组周围空气污染大则每天应对主机清洗一到两次，以保证送出的冷气清爽、干净、建议采用“白远”功能模式运行。
2、机组运行半年后应对其底盆（包括底盆内的水泵、进水阀、排水阀、液位开关等清洗）及蒸发介质清洗一次，且清洗时水压不能太高，以免冲坏湿帘。
3、长时间停用时，为防止冻结损坏机体及蚊虫滋生，应关闭自来水机器进水阀门，再让机组进入（清洗模式）而排尽水箱底盆里的余水，西北地区冬季停机时，将主机盖上防尘网并锁紧，以防晚秋初冬沙尘暴堵塞蒸发介质。
4、检修机组时应关闭控制箱供电电源，维修人员在机内时要挂维修牌严禁开启电源。
5、基机组因故障跳闸时请先排除故障后再按下空气开关。
6、首次使用有木屑味散出，连续使用24小时后消失。
7、防雨百叶窗不能受力，在安装或其这情况下严禁将百叶窗作为受力点而用手去搬动。
8、记忆电池两年后应注意更换。
9、主机座架在两年后应做一次防腐锈处理（刷漆），以后每年应定期对主机架的牢固性进行检查。
1.need to clean one or two times each day if these machine around with large polutional air that can ensure imput refreshing air. Suggest adopt “automatic” function running
2.need to clean the bottom of these that include pump, feed valve, drain valve, liquid level switch and evaporation media. The water pressure needn't too high in case break water shade.
3.when these mechine have a long time not work should close running water mechine feed valve in case break the body and cause bacterial blooms. And run over bottome water when these mechine run into clean model. In northwest, And should be covered when stop in case that dustry blowe into and clogging the evaporate media.
4.should close the control box power when checking the mechine, and hange up“strictly prohibit power” when maintain .
5.before closeing air-break switch clean malfuncation, when meet power off for mechine trouble.
6.If you first used it would smell a little wood smell. It could wear off when use it 24 hours continue.
7.rainproof jalousie can not force. So when install or other case do force move it by hand.
8.recalling-battery need to change after 2 years used
9.main mechine should be do anti-corrosive treatment biennially, and regular check it's securely every year.
