[0002] HVAC is an integral part of a building. It includes heating, ventilation, and air conditioning. The abbreviation for these three functions is HVAC. HVAC is a central air conditioner for each household. The central air conditioner is divided into a water system and a Freon system. The common split Freon air conditioner in the home can only solve the problem of heating and cooling, but not the air handling process. Therefore, a filtering structure is installed on the HVAC equipment.
[0003] However, the existing warm-pass filter equipment is usually fixed to the wall by bolts, which makes it difficult to disassemble, not conducive to later cleaning, and has a short service life. The bolts and bolt holes are corroded and damaged, and the bolt fixing method is point-type fixing with poor stability.
