Description
The snap band is a device used to secure and seal filter bags and is commonly used in equipment such as filters, vacuum cleaners and air purifiers. Its main functions include the following:
- Fixing the filter bag: The snap band fixes the filter bag to the filter element base or filter bag slot of the equipment to prevent the filter bag from loosening or falling off during operation of the equipment. This ensures that the filter bags work in the correct position and cannot be pulled away by air flow or suction forces.
Sealing performance: Dust filter bag snap bands are usually designed to provide good sealing performance. They ensure a tight fit at the connection points between the filter bag and the equipment, preventing air or dust from bypassing the filter bag and entering the interior of the equipment. This sealing performance is very important for the filtration effect of the equipment. - Prevent air leaks: In equipment such as vacuum cleaners and air purifiers, if the filter bags are not properly secured, air leaks may occur, which is when air, dust or dirt bypasses the filter bags and enters the interior of the equipment or returns to the indoor air. The purpose of the dust filter bag snap band is to ensure that the air inside the device flows through the filter bag, not around it.
- Extended filter bag service life: By properly fixing the filter bag, the filter bag is prevented from being damaged or worn due to vibration or airflow impact while the equipment is running. This can extend the service life of the filter bag, reduce the frequency of replacement, and reduce maintenance costs.
