The fully automated, PLC-controlled purifiers effectively remove free, emulsified and dissolved water, free and dissolved gases, and particulate contamination down to 3xa0µm from light transformer oils to heavy lubricating oils at a flow rate of 8xa0gpm (30xa0l/min). Typical high-moisture applications include hydroelectric power, pulp and paper, offshore and marine.

CN95 certification is setting new standards in the cabin air filter market, although it is not yet a mandatory requirement for the sales of cabin air filters in China.

The pre-filter was developed by Hengst Filtration and the development of the housing was a joint effort between Hengst and TBH. All extraction systems sold by TBH GmbH as part of its DF-series will now be equipped with the InLine patient filter.

The fire safety of room ventilation systems in buildings is regulated by EN 15423. For air filters, it states that materials must be classified regarding reaction to fire under EN 13501-1

The primary filter screen of the fresh air fan can filter more than 10 μ m of air pollution particles; the filter materials of the medium and high efficiency filter screens are significantly denser and tighter than the primary filter screen of the first layer, and can filter PM2.5 and smaller nanometer ultra-fine particles, the pore diameter of which is very small, playing a precise and fine filtering role in the whole air duct.

According to the maintenance cycle of the vehicle, when the ambient air quality is generally good, it is sufficient to clean the air filter regularly every 5000 kilometers. However, when the ambient air quality is poor, it is best to clean it every 3000 kilometers in advance. , Car owners can choose to go to the 4S shop to clean up, or you can do it yourself.

Filtration specialist Mann+Hummel and recycling and environmental services company Alba Group are expanding their partnership to tackle vehicle emissions.

Mann+Hummel announced its Mann-Filter air filter C 24 005 is now utilizing recycled synthetic fibers.

Gasoline filter is abbreviated as steam filter. Gasoline filters are divided into carburetor type and electronic injection type. For gasoline engines that use carburetor, the gasoline filter is located on the inlet side of the fuel transfer pump. The working pressure is relatively small. Generally, nylon shells are used. The gasoline filter is located on the outlet side of the fuel transfer pump, and the working pressure is relatively high. A metal casing is usually used. The filter element of the gasoline filter mostly uses filter paper, and there are also gasoline filters that use nylon cloth and molecular materials. The main function is to filter out impurities in the gasoline. If the gasoline filter is dirty or clogged. In-line filter paper gasoline filter: The gasoline filter is inside this type of gasoline filter, and the folded filter paper is connected to the two ends of the plastic or metal/metal filter. After the dirty oil enters, the outer wall of the filter passes through layers of filter paper After filtering, it reaches the center and clean fuel flows out.

Air filtration has three modes: inertia, filtration and oil bath. Inertia: because the density of particles and impurities is higher than that of air, when the particles and impurities rotate or make sharp turns with the air, the centrifugal inertial force can separate impurities from the gas stream.

The air filter consists of two parts: a filter element and a shell. The main requirements of an air filter are high filtration efficiency, low flow resistance, and continuous use for a long time.

The filter element of the air cleaner is divided into two types: dry filter element and wet filter element. The dry filter element material is filter paper or non-woven fabric. In order to increase the air passage area, most of the filter elements are processed with many small folds. When the filter element is slightly fouled, it can be blown with compressed air. When the filter element is seriously fouled, it should be replaced with a new one in time.

Since China joined WTO in 2001, it has entered the tenth year. China’s automobile industry has achieved rapid development during this decade. And the automotive filter industry, which is inseparable from the development of the entire vehicle, has also developed rapidly. Water rises. My country exported 58.775 million auto filters, an increase of 13.57% over 2010, and the amount involved was US$127 million, an increase of 41.26% over 2010.
