1. Hattype coarse stranier, which is mainly used for the air filter of the small-bore farm-oriented internal combustion engine, whose structure is tight and it can discharge dust automatically.
2. Basinshaped coarse
stranier, which is mainly used in tractor or the air filter of the
small-bore farm-oriented internal combustion engine,the space that
occupys is large and there is no function to discharge dust, it needs to
remove the dust in the basin by hand.
3.Blade ring type coarse strainer, which is commonly used in big internall combustion engine air filter.
As it is installed in air filter and does not occupy extra space, it
can install automatic dust-discharge device according to the
requirements,it is the ideal coarse strainer for the internal combustion
engine air filter.
4.Tangential air inflow
tpye of coarse filter,which is mainly used in small-bore farm-oriented
internal combustion engine air filter and occupys little space and the
processing technology is better, it installs automatic dust-discharge.
5.Spiral-flow pipe type
of coarse filter, which is commonly used in large engineering machinery
air filter in bad environment, whose processing technology requirements
is higher, the coarse efficiency is higher and it can discharge the
dust automatically, it is the ideal coarse filter for industrialengineering machniery.
