Because people take good care of their health now, the ventilation equipment inside the building is essential. Today's ventilation equipment market is good, the price is not high, so the range of use is relatively wide. The following is the introduction of some causes and measures for dust contamination of ventilation equipment. Let's take a look.

　　风管清洗是保证洁净的一道重要工序，国产镀锌钢板都没有经过脱脂处理，钢板表面涂有大量的油脂，若不清洗干净，则会在运输、安装及以后的运行过程中沾染灰尘，使用过程中可会导致一次性的积尘飞扬。

　　Air duct cleaning is an important process to ensure cleanliness. Domestic galvanized steel plates are not degreased, and the surface of steel plates is coated with a large amount of grease. If not cleaned, dust will be stained during transportation, installation and subsequent operation, which may lead to primary dust flying during use.

　　通风设备厂指出这会使过滤器前的空气含尘浓度增大，这对过滤器的使用周期和效率都有很大的影响，所以必须清洗。

　　The ventilation equipment factory points out that this will increase the dust concentration in the air before the filter, which has a great impact on the service cycle and efficiency of the high efficiency filter, so it must be cleaned.

　　通风设备清灰的过程：清水清洗→中性清洗剂清洗→工业酒精脱脂→清水再清洗→洁净布擦洗→白绸布擦拭检验。合格以后的风管立即用塑料薄膜进行封口处理。

　　The process of dust removal of ventilation equipment: clean water → neutral detergent cleaning → industrial alcohol degreasing → clean water re cleaning → clean cloth scrubbing → white silk cloth wiping inspection. The qualified air duct shall be sealed with plastic film immediately.
