　　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.

　　風管清洗是保證潔凈的一道重要工序，國產鍍鋅鋼板都沒有經過脫脂處理，鋼板表面涂有大量的油脂，若不清洗干凈，則會在運輸、安裝及以后的運行過程中沾染灰塵，使用過程中可會導致一次性的積塵飛揚。

　　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.

　　通風設備廠指出這會使過濾器前的空氣含塵濃度提升，這對過濾器的使用周期和效率都有很大的影響，所以建議清洗。

　　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.

　　通風設備清灰的過程：清水清洗→中性清洗劑清洗→工業酒精脫脂→清水再清洗→潔凈布擦洗→白綢布擦拭檢驗。合格以后的風管立即用塑料薄膜進行封口處理。

　　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.

　　通風設備沾灰原因及措施，一般的，通風設備的除塵可用清水或純水加中性清洗劑，而脫脂的方法可用工業酒精即可。更多通風設備報價的詳情，可以訪問的網站進行咨詢，我們的客服人員很高興能為您服務。

　　Generally, clean water or pure water plus neutral detergent can be used for dust removal of ventilation equipment, while industrial alcohol can be used for degreasing.
