What is the appropriate wind speed for a HEPA filter?

The surface velocity and filtration velocity of a cleanroom HEPA filter can reflect the airflow capacity of the cleanroom HEPA filter. Surface velocity refers to the passing airflow speed on the section of the cleanroom HEPA filter, generally expressed in m/s, V=Q/F3600. The surface wind speed is an important parameter that reflects the structural characteristics of the cleanroom HEPA filter. The filtration speed refers to the speed of airflow over the area of the filter material, generally expressed in...

Liquid tank HEPA filter has many advantages and features

The liquid tank type HEPA filter is a type of HEPA filter without partitions. The filter mainly uses ultra-fine glass fiber as the filter medium. The middle spacing line mainly uses imported hot melt adhesive and is made of polyurethane. Sealant, the external structure is made of aluminum, usually available in different thicknesses. Two DOP joints are installed above the air supply port of the filter, one for dust generation and the other for detection. This design makes it easier...

Analysis of factors affecting the filtration efficiency of glass fiber filters

The filtration precision of the glass fiber filter is very high and can capture dust particles and various suspended solids with a particle size of less than 0.5 microns. However, in addition to the filtration precision of the device itself, the filtration efficiency of the filter will also be affected by other factors. Today, the editor of Qingyong Purification will tell you what factors affect the filtration efficiency of fiberglass air filters? ​ Factor 1: Temperature ​ The molecules in the air are...

Clean Room Noise Requirements

The clean room not only has strict requirements on the cleanliness of the indoor air but also has certain national standard parameters for the noise of the operating environment because the clean room workshop is a relatively closed and depressing environment. If the noise is not properly controlled, it is easy to cause Workshop staff and the deterioration of the production environment. 1. Measurement method of noise When the area of the room is not greater than 50m², only one point...

What are the points to pay attention to in the construction of clean air conditioning system?

1. The material for making the air duct is the basic condition to ensure the cleanliness of the air conditioner Material selection. Clean air-conditioning system air ducts are generally processed with galvanized steel sheets. The galvanized steel sheet should be of high quality, the standard of galvanized layer should be >314g/㎡, and the coating should be uniform, without peeling and oxidation. Hangers, reinforcement frames, connecting bolts, washers, air duct flanges, and rivets should all be galvanized parts. Flange pads should...
