Problems solved by technology

There are profiles for fixing filter elements in EFU air filters. Generally, the height of the profile on the air filter in EFU equipment is 70mm / 80mm. It is inconvenient to install EFU air filters at positions with height restrictions, and the thickness Larger filter elements have greater resistance when filtering air, which affects the filtering effect

Abstract

The invention relates to a special efficient air filter for an EFU. The air filter comprises a cuboid filter element and an outer frame used for fixing the filter element and installed on the four side end faces of the filter element. The filter element is composed of two layers of sealed skirt type filter paper and thermoplastic adhesive between the two layers of filter paper. The outer frame comprises two H-type transverse profile frames and two H-type longitudinal profile frames and provided with rivet nuts connected with a box. The air filter is ultra-thin, low in energy consumption, low in noise and extremely low in filter element resistance, and profiles of the outer frame are good in strength and convenient to install and fix.

Description

[0001] Technical field: [0002] The invention relates to an air purification device, in particular to an EFU special-purpose high-efficiency air filter. [0003] Background technique: [0004] EFU (Equipment fan filter unit) is the English abbreviation for equipment fan filter unit. In the air purification industry, EFU equipment is a very important product. There are profiles for fixing filter elements in EFU air filters. Generally, the height of the profile on the air filter in EFU equipment is 70mm / 80mm. It is inconvenient to install EFU air filters at positions with height restrictions, and the thickness Larger filter elements have greater resistance when filtering air, which affects the filtering effect. [0005] Invention content: [0006] In view of the above technical problems, the present invention has designed a special high-efficiency air filter for EFU, including a cubic filter element and an outer frame for fixing the filter element and being installed on the fo...
