The air filter filters air to block the dust from entering the engine,so as not to affect the combustion of fuel in the engine.Air filters are divided into dry and wet types.And we will share knowledge about dry air filters at Gzsycc.com.The dry air filter consists of an air filter cartridge,a pre-filter device,a main filter element, a dust collection tray,a dust discharge bag, a blocking indicator (optional) etc composition.

Forklift dry air filter maintenance and maintenance

1.Dry air filter working principle

The first stage of the dry air filter is a prefilter,It can swirl the air entering the air filter,By centrifugation, the larger mass of dust particles is separated from the intake air into the periphery of the centrifuge zone.The coarse filtered air enters the interior of the paper filter and is blocked by the filter pores.In addition,the polymerization of dust itself forms an additional filter layer,which further separates the fine dust in the air and adheres to the outer surface of the paper filter element.

2.Air filter maintenance

(1)The components of the air cleaner should be installed in the correct position and cannot be reversed.Once the air filter housing is broken,it must be replaced in time.If the seal at both ends of the filter element is degummed,it should be replaced.


(2)The filter paper is a very fine fiber material filled with synthetic resin,so it must not be cleaned in water or oil,do not allow contact with water, fire or oil.When removing dust from the paper filter element, use a clean cloth or rubber stopper to block the ends of the filter element,brush the surface of the filter core with a soft brush in the direction of the crease,and gently tap the end face to remove dust.Can also be used compressed air or pump blown (pressure should not exceed 0.2 ~ 0.29MPa, to prevent damage to the filter paper) from the inside of the filter element to blow away the dust adhered to the outer surface of the filter element.After removing the dust from the paper filter element,check the filter element for damage.If it is damaged,replace it immediately.

(3)The connection between the air cleaner assembly and the air intake pipe or other connections in the air intake system must be connected firmly and tightly,and no air leakage is allowed.It is forbidden to have a short circuit of the air intake.

(4)Under normal conditions,the filter element needs to be replaced every six months or 1000 hours.The paper filter element must be replaced at most 2 or 3 times.Air intake system with secondary air filter installed needs to increase the frequency of maintenance of the first stage air cleaner,to prevent the inlet back pressure from exceeding the engine limit,the performance of the engine is affected.


The air filter removes dust and other impurities that enter the air of the carburetor,Therefore,the air filter is a clean product.You can clean or replace the air filter regularly according to your working environment.This can extend the service life of the forklift. Thank you!
