The vast majority of 6 cylinder models construction machinery, configuration swirl air filter.

Swirl type air filter structure

The swirl type air filter is composed of a swirl filter, a main fine filter element and a safety filter element.

The paper main fine filter element is sheathed on one side with the safety filter element, and the filter element is communicated with the rubber injection pipe of the exhaust pipe.The cyclone tube department of plastic products, to prevent the collision of heating.Air into the coarse filter, the effect of the centrifugal force of the cyclone tube, most of the dust particles in the air, fall into the dust chamber of the lower end of the vortex tube. When the engine exhaust gas through the throat, the throat of smaller diameter, flow rate increases, the formation of local vacuum, the dust in the dust chamber by a rubber tube suction ejector tail tube, and diesel exhaust gas discharged into the atmosphere together.

After the coarse filter, clean air, through the paper fine filter, the safety filter into the intake manifold.

In order to remind the operator to maintain the filter, the air filter outlet end is equipped with a vacuum alarm. The alarm case is grounded, and the indicator light is installed on the instrument panel. When the air filter element dust particles for a long time, the intake resistance increases, the air intake manifold side vacuum increases, when the air is more than 5.9-6.4pa, the indicator light flashes, the operator should be timely maintenance of air filter

In order to facilitate the removal of dust, to replace the filter, filter housing and filter cartridge can be removed.
