Main types of primary air filter
1. The cap type coarse filter is mainly suitable for air filters of small bore agricultural internal combustion engines, with a compact structure and automatic dust removal.
2. The basin type coarse filter is suitable for internal combustion engine air filters used in agricultural machinery such as tractors. It occupies a large space and does not have an automatic dust removal function. It requires manual removal of dust from the dust accumulation basin.
3. Blade ring type coarse filter, commonly seen in large internal combustion engine air filters. Due to its installation in the air filter, there is no additional space required, and automatic dust removal devices can be installed as needed, making it an ideal coarse filter for internal combustion engine air filters.
4. Tangentially aspirated coarse filter, suitable for air filters of small bore agricultural internal combustion engines, with small space occupation, good processing technology, and equipped with automatic dust removal device.
5. Swirl tube type coarse filter is commonly used in large engineering machinery with harsh environments, such as internal combustion engine air filters. It has high process requirements, the highest coarse filtration efficiency, and can automatically remove dust. It is an ideal coarse filter for engineering machinery air filters.
