High-efficiency supply air outletthe main types are as followsWith partitioned high-efficiency filter supply air outlets，Unobstructed high-efficiency filter air supply outlet。The difference between the two is that they use either the partitioned high-efficiency filter or the non-partitioned high-efficiency filter.
The high-efficiency air supply outlet is called HEPA BOX. Depending on the sealing method, it can be divided into dry sealing with a liquid tank (wet test) or dry sealing.
1、Dry-type sealed high-efficiency air outlet：The pad-type filter, also known as the "high-efficiency air inlet", has the following features: easy installation, low cost. However, its drawback is that it may leak if the sealing is not good. Application: It is mainly used in electronic factory buildings.
2、Liquid tank sealed high-efficiency air supply outlet：The liquid tank filter is connected to the edge of the box, and is referred to as "liquid tank high-efficiency air outlet".Features: Good sealing performance, higher cost, and more complex construction.
Applications: Currently, many advanced pharmaceutical factories in China adopt this structure.
At present, all the air vents are of the downward-blowing type, and their structures are all designed based on this condition.

Selection of supply air outlets
Choose between liquid tank air outlets or ordinary high-efficiency air outlets based on the customer's on-site requirements:
Determine the size (including thickness) of the air outlet filter based on the total supply air volume and the number of air outlets provided by the customer;
Select the size of the box based on the size of the filter;
Choose the efficiency of the filter based on the cleanliness requirements;
Select the structure of the air inlet based on the customer's requirements;
Choose whether to have a flow rate regulating valve, dust emission ring, pressure difference test port, insulation cotton, etc. according to the customer's requirements.
