LR-B012 Sａnd Dust Test Chamber Laboratory Customized
Use
It simulates the destructive effect of natural wind and sａnd climate on the product and is suitable for testing the seal performance of the product enclosure.It is mainly used for testing the two grades of IP5X and IP6X specified in the enclosure protection standard.Carrying dust vertical circulation of air,test equipment with dust can be recycled,the whole duct made of imported advanced stainless steel plate at the bottom of the air duct connected with taper hopper interface,fan outlet directly connected to the air duct,ａnd then in the appropriate position will studio top spread port access studio,forming vertical blowing dust”O”type closed loop system,make the air can flow smoothly,large extent makes the dust dispersed evenly.A single high power low noise centrifugal fan is used to adjust the wind speed according to the test requirements.
