Hitachi 4459549 air filter

Product introduction

Hitachi 4459549 air filter is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms.

The engine in the working process to suck in a lot of air, if the air is not filtered clear, the dust suspended in the air is sucked into the cylinder, it will accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and the cylinder, will cause serious "cylinder pulling" phenomenon, which is particularly serious in the dry and sandy working environment. The air filter is installed in the front of the carburetor or the intake pipe to filter the dust and sand in the air and ensure that enough clean air is entered into the cylinder.

Matters needing attention

During installation, whether the air filter and the engine intake pipe are connected by flanges, rubber pipes or directly, they must be tight and reliable to prevent air leakage. The two ends of the filter element must be installed with rubber washers; The wing nut holding the outer cover of the air filter should not be screwed too tightly to avoid crushing the paper filter element.

Maintenance

1.The filter element is the core component of the filter, made of special materials, belongs to the wear parts, need special maintenance, maintenance;

2. When the filter works for a long time, the filter element has intercepted certain impurities, which will lead to the increase of pressure and the decrease of flow, at this time, it needs to be cleaned in time;

3. When cleaning, we must pay attention to the deformation or damage of the filter element.
