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

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. 

Importance of air filter

Everyone knows that the engine is the heart of a car, and the oil is the blood of the car. And do you know? There is also a very important part of the car, that is the air filter. The air filter is often overlooked by the drivers, but what everyone does not know is that it is such a small part that is very useful. The use of inferior air filters will increase your vehicle’s fuel consumption, cause the vehicle to produce serious sludge carbon deposits, destroy the air flow meter, severe throttle valve carbon deposits, and so on.We know that the combustion of gasoline or diesel in the engine cylinder requires inhalation of a large amount of air. There is a lot of dust in the air. The main component of dust is silicon dioxide (SiO2), which is a solid and insoluble solid, which is glass, ceramics, and crystals. The main component of the iron is harder than iron. If it enters the engine, it will aggravate the wear of the cylinder. In severe cases, it will burn engine oil, knock the cylinder and make abnormal noises, and eventually cause the engine to be overhauled. Therefore, in order to prevent these dust from entering the engine, an air filter is installed at the inlet of the engine’s intake pipe.

Does the construction machinery filter need to be replaced？

In the process of use and management of construction machinery filter elements, it will always cause a problem for everyone, whether the filter element should be replaced or not. How to judge the quality of the filter element? Based on years of production experience, PAWELSON® will analyze the following situations for you: When should the filter element be replaced?​

Many users think that the bypass valve of the hydraulic oil filter and the safety valve of the system have the same function: after the hydraulic oil filter element is blocked, the bypass valve is opened, and the full flow of the turbid liquid in the system will pass through, which will affect the system. This is a mistake. awareness. When the bypass valve of the filter is opened, the pollutants blocked by the filter element will re-enter the system through the bypass valve. At this time, the pollution concentration of the local oil and the precision filter element will greatly damage the hydraulic components. The previous pollution control also will lose its meaning. Unless the system requires very high work continuity, choose a construction machinery filter element without a bypass valve. Even if a filter with a bypass valve is selected, when the pollution of the filter blocks the transmitter, it is necessary to clean or replace the filter element in time. This is the way to ensure the safe and reliable operation of the system. In fact, when it is found that the filter element is blocked and an alarm is issued, it has already indicated that the filter element should be replaced. Insistence not to replace will cause certain damage to the equipment. It is recommended to replace it immediately if circumstances permit.

PAWELSON® explained, how to judge the quality of construction machinery filter elements?

Many users use the service life of the filter to judge the performance of the filter because they do not have oil contamination detection equipment. The speed of clogging of the filter shows the good or bad performance of the filter, both of which are one-sided. Because the filtration performance of the filter is mainly reflected by the performance indicators such as filtration ratio, dirt holding capacity, and original pressure loss, the longer the service life of the precision filter element, the better, only under the same working conditions and the cleanliness of the hydraulic system.

There are also users who think that the more precise the accuracy, the better the quality. Of course, this idea is also one-sided. The filter accuracy is too precise. Of course, the filtration blocking effect is better, but at the same time, the flow rate will not meet the requirements, and the filter element will be blocked faster. Therefore, the accuracy of the construction machinery filter element suitable for work is of good quality.
