Air Filter Elements

1.Using imported high quality materials, high precision, high dust holding capacity, good permeability, stable performance.Special filter paper embossing technology, fold uniformly, vertically and smoothly, more folds, more filter area increases.
2.With pioneered net lock technology, no burr, no rust; with thick net,so hardness is stronger, can effectively protect filter paper from Injury, and with grid smaller net, can effectively prevent particles to enter inside.
3.Using high-quality sealing tape, strong and flexible, not hard or bad;using AB glue, epoxy glue double paste, sealing performance enhanced.
4.Use high quality environmental friendly PU materials and molding technology, to ensure good end-elasticity, can against high pressure, and high or low temperature, seal firmly.

FAQs

1.Can you drive without an air filter?
Without a functional air filter, dirt and debris can easily enter the turbocharger, causing extreme damage. … Without an air filter in place, the engine may also be sucking dirt and debris in at the same time. This can cause damage to internal engine parts, such as valves, pistons and cylinder walls.
2.Is air filter same as oil filter?
Types of filters
The intake air filter cleans the air of dirt and debris as it enters the engine for the combustion process. … The oil filter removes dirt and other debris from the engine oil. The oil filter sits to the side and at the bottom of the engine. The fuel filter cleans the fuel used for the combustion process.
3.Why do I have to change my air filter so often?
You have leaky air ducts
Leaks in your air ducts introduce dust and dirt from areas like your attic. The more dirt a leaky duct system brings into your home, the more dirt your air filter accumulate

Excavator air filter replacement steps

The air filter of the excavator is one of the very important supporting products of the engine. It protects the engine, filters out hard dust particles in the air, provides clean air to the engine, prevents engine wear caused by dust, and improves the reliability and durability of the engine. Sex plays a key role.

When the intake pipe or filter element is blocked by dirt, it will lead to insufficient intake air, causing the diesel engine to make a dull sound when accelerating, weak operation, rising water temperature, and gray-black exhaust gas. If the air filter element is improperly installed, the air containing a large amount of impurities will not pass through the filter surface of the filter element, but will directly enter the cylinder from the bypass.

In order to avoid the above phenomenon, the filter must be installed according to the regulations, and the daily maintenance specifications must be strengthened. When the excavator reaches the specified maintenance time, generally the coarse filter is replaced at 500 hours, and the fine filter is replaced at 1000 hours. So the question is, what are the normal steps to replace the air filter?

Step 1: When the engine is not started, open the rear side door of the cab and the end cover of the filter element, remove and clean the rubber vacuum valve at the lower cover of the air filter housing, check whether the sealing edge is worn or not, and replace the valve if necessary. (Note that it is forbidden to remove the air filter element during engine operation. If you use compressed air to clean the filter, you must wear protective goggles).
Step 2: Disassemble the outer air filter element and check whether the filter element is damaged. If so, please replace it in time. Use high-pressure air to clean the outer air filter element from the inside out, taking care that the air pressure should not exceed 205 kPa (30 psi). Irradiate the inside of the outer filter with light. If there are any small holes or residues of thinner on the cleaned filter element, please replace the filter.
Step 3: Disassemble and replace the inner air filter. Note that the inner filter is a one-time part, please do not wash or reuse it.
Step 4: Use a rag to clean the dust inside the housing. Note that it is forbidden to use high-pressure air for cleaning.
Step 5: Correctly install the inner and outer air filters and the end caps of the air filters, making sure that the arrow marks on the caps are upwards.
Step 6: The outer filter needs to be replaced once after the outer filter is cleaned 6 times or the working time reaches 2000 hours. When working in harsh environments, the maintenance cycle of the air filter should be shortened appropriately. If necessary, an oil bath pre-filter can be used, and the oil inside the pre-filter should be replaced every 250 hours.
