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.

Application range

Water and oil filtration, petrochemical industry, oil field pipeline filtration;
Fuel filtration of refueling equipment and construction machinery and equipment;
Equipment filtration in water treatment industry;
Pharmaceutical and food processing fields;
Rotary vane vacuum pump oil filtration;

Importance of your air filter

Protecting Your Engine
Designed to allow clean air into the engine, the air filter is your vehicle’s first line of defense by preventing airborne contaminants such as dirt, dust and leaves from getting pulled into the engine compartment. Over time, the engine air filter can become dirty and lose its capacity for filtering the air going into the engine. If your air filter becomes clogged with dirt and debris, it can have a profound effect on the performance of your car’s engine.

How to choose air filter?

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.

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.
