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
Our Main business
We mainly produce good quality filters instead of original ones.
Our leading products have various of AIR filter, CABIN filter, FUEL filter, OIL filter, HYDRAULIC filter, FUEL WATER SEPARATOR filter ect.
Air filter refers to a device that removes particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor air filter, 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 is composed of a filter element and a shell. The main requirements of air filtration are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance.
1.Check the appearance:
First look at whether the appearance is exquisite workmanship? Is the shape neat and smooth? Is the surface of the filter element smooth and flat? Secondly, look at the number of wrinkles. The more the number, the larger the filter area and the higher the filtration efficiency. Then look at the wrinkle depth, the deeper the wrinkle, the larger the filter area and the greater the dust holding capacity.
2.Check The Light Transmittance:
Look at the air filter at the sun to see if the light transmission of the filter element is even? Is the light transmittance good? The uniform light transmission and good light transmission indicate that the filter paper has good filtration accuracy and air permeability, and the air intake resistance of the filter element is small.

Pharmaceutical and food processing fields;
Rotary vane vacuum pump oil filtration;
1. The filter element is the core component of the filter. It is made of special materials and is a vulnerable part that requires special maintenance and maintenance;
2. After the filter has been working for a long time, the filter element in it has blocked a certain amount of impurities, which will cause an increase in pressure and a decrease in flow rate. At this time, it needs to be cleaned in time;
3. When cleaning, be careful not to deform or damage the filter element.
Generally, depending on the raw materials used, the service life of the filter element is different, but with the extension of use time, impurities in the water will block the filter element, so generally the PP filter element needs to be replaced in three months; the activated carbon filter element needs to be replaced in six months ; As the fiber filter element cannot be cleaned, it is generally placed on the back end of PP cotton and activated carbon, which is not easy to cause clogging; the ceramic filter element can usually be used for 9-12 months.

With the advancement of engine technology, the requirements for excavator filters are getting higher and higher. The most harmful to the working performance and life of the excavator is the impurity particles and pollution entering the diesel engine. They are the number one killer of engines. Filters are the only way to avoid foreign particles and contamination. So, how to identify the quality of the filter element, and what are the hazards of inferior filters.
Excavator filter element quality
First, the common is the microporous filter paper filter element
The most common oil filter on the market today is basically a microporous filter paper filter. It is a special filter paper impregnated with this resin, which is heat-cured to increase its stiffness and strength, and then packed into an iron case. The shape is better maintained, and it can withstand a certain pressure, the filtration effect is better, and it is relatively cheap.
2. The waves of the filter element layer by layer look like a fan
Then, in the process of using this pure paper filter element, it is easy to be squeezed and deformed by this oil pressure. It is not enough to strengthen it by this paper. In order to overcome this, a net is added to the inner wall of the filter element, or a skeleton is inside. In this way, the filter paper looks like layers of waves, very similar to the shape of our fan, wrap it in a circle to improve its lifespan.
3. The service life is calculated according to the filtering effectiveness
Then the life of this machine filter is calculated according to its filtering effectiveness. It doesn’t mean that the filter has been used until the filter is blocked, and the oil can’t pass, and it is the end of its life. It means that its filtering effect is poor, and when it cannot play a good cleaning role, it is considered to be the end of its life.
Excavator filter element
Basically, its replacement cycle is around 5,000 to 8,000 kilometers. A good brand can last for more than 15,000 kilometers. For the oil filter we usually buy every day, we understand that 5,000 kilometers is almost its longest life. .
The filter was originally used to filter the harmful impurities in various substances entering the diesel engine. The engine can work normally under various working conditions and can reach the specified service life. However, counterfeit filters, especially inferior filters, not only fail to achieve the above effects, but instead bring various hazards to the engine.
Common hazards of inferior filter elements
1. Using cheap filter paper to make excavator filter element, because of its large pore size, poor uniformity and low filtration efficiency, it cannot effectively filter out harmful impurities in the material entering the engine, resulting in early engine wear.
2. The use of low-quality adhesives cannot be firmly bonded, resulting in a short circuit at the bonding point of the filter element; a large number of harmful impurities enter the engine, which will reduce the life of the diesel engine.
3. Replace oil-resistant rubber parts with ordinary rubber parts. During use, due to the failure of the internal seal, the internal short circuit of the filter is formed, so that part of the oil or air containing impurities directly enters the excavator engine. Causes early engine wear.
4. The material of the center pipe of the excavator oil filter is thin instead of thick, and the strength is not enough. During the use process, the center pipe is sucked and deflated, the filter element is damaged and the oil circuit is blocked, resulting in insufficient engine lubrication.
5. Metal parts such as filter element end caps, central tubes, and casings are not treated with anti-rust treatment, resulting in metal corrosion and impurities, making the filter a source of pollution.
