Excavator Air Filter 301.6 301.5 Model Part Number 533-3117 533-3118 Manufacturer Universal Model 301.8 301.7 CR302.CR
The air filter is mainly responsible for removing particulate impurities from the air. When piston type machinery (such as internal combustion engines, reciprocating compressors, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts: the filter element and the housing. The main requirements of an air filter are high filtration efficiency, low flow resistance, and the ability to be used continuously for a long time without maintenance.
The engine is a very precise component, and even the smallest impurities can damage the engine. Therefore, before entering the cylinder, the air must first pass through a fine filter of the air filter before entering the cylinder. The air filter is the guardian angel of the engine, and the condition of the air filter is related to the lifespan of the engine. If a dirty air filter is used during the operation of a car, it will cause insufficient engine intake, incomplete fuel combustion, unstable engine operation, decreased power, and increased fuel consumption. Therefore, the car must keep the air filter clean.
1. Construction machinery often operates in high dust environments such as mines and construction sites. Air filters need to have extremely high filtration efficiency (usually up to 99.5% or more), which can effectively intercept small dust, stone powder and other impurities in the air, prevent them from entering the engine cylinder, and avoid serious wear and tear of plugs, cylinders and even "cylinder pulling" faults.
2. To adapt to long-term, high-intensity continuous operations, air filters commonly use materials such as metal wire fabrics, foam materials, or specially treated filter paper. These materials have higher mechanical strength and weather resistance, and can withstand physical impacts and long-term use under harsh working conditions.
3. In extremely dusty environments, wet air filters are still widely used. This type of filter element captures dust by adhering to the oil medium, with high filtration efficiency. The metal filter element is more resistant to wear and flushing than dry filter paper, making it particularly suitable for large diesel engines.
4. Efficient air filters should ensure filtering effectiveness while minimizing intake resistance to ensure sufficient and smooth airflow for the engine, maintaining power output and fuel efficiency. Modern construction machinery filter cartridges achieve high dust holding capacity and long service life by optimizing structure and materials, reducing maintenance frequency in remote construction sites and lowering operating costs.
5. The sealing performance between the filter element and the housing is crucial. Any unfiltered air entering the engine through a bypass will cause accelerated wear and tear. Therefore, the rubber seals and other components of the air filter element in construction machinery need to ensure absolute sealing under various vibrations and pressures.
Q1.Do you have MOQ?
Depends on different ideas, Can be negotiated.The larger the quantity is, the competitive the unit price will be.
Q2.Should the customer pay the delivery fee,How much is it?
For the delivery fee,many samples are be requested to be sent,so we must get delivery fee. If you tell me to use the appointed Express,you will give me your express account or you will pay according to the Express. If you do not request,I will choose a cheap one in China.
Q3.How about the after sale service?
1)We will always keep the quality the same as the buyer's samples and if there is something with the quality,we will make compensation for our customers.
2)We will suggest our packing and take charge in our packing,we will keep the goods safe in the delivery.
3)We will trace the goods from the production to selling,we will solve the problems in the selling for our customers.
Q4.When can I get a price?
We usually quote within 24 hours after we get your inquiry.
Q5: What are the materials of the filter element? What are the corresponding accuracy ranges?
According to the classification of filter materials, there are: oil filter paper: 10-50um, glass fiber: 1-70um, HV glass fiber: 3-40um, metal mesh: 3-500um, sintered felt: 5-70um, and line gap filter: 15-200um.
Q6: What brands of filter cartridges do you make?
Our factory produces alternative universal filter elements for foreign brands such as Pall, Hedek, Dasheng, Parker, and Rexroth, as well as national standard oil suction filter elements, oil return filter elements, high-pressure filter elements, and coalescence dehydration filter elements. We support non-standard customization. We welcome samples or drawings for processing and customization.
Q7: How can customers choose the appropriate filter size when making their own filters?
We need to provide the flow rate, pressure, external dimensions, accuracy, filter medium and other parameters of the filter designed by the customer. We will provide the customer with the selected filter element size and quantity based on the filter size.
Q8: Is there any difference between filtering kerosene, gasoline, diesel filters and general hydraulic oil filters?
The sealing materials used in the filter element are different. Generally, the sealing ring of hydraulic oil filter element is nitrile rubber, while filtering media such as kerosene, gasoline, and diesel requires the use of fluorine rubber rings.
