Key Advancements in Automotive Filter Technology
With an upsurge in passenger car making and growth of two-wheelers demand mainly in BRICS nations (Brazil, Russia, India, China and South Africa) has increased the automotive air filters market size. Along with promising regulations and dynamic industrialization in China, India, Vietnam, and South Korea are also initiating industry growth. According to a recent report, the global automotive filter market is projected to surpass US$ 18 Bn in revenues by 2022.
An automotive air filter confines the dust particles and other harmful elements from entering the engine or fuel system, thereby, improving the mileage of vehicles. Automotive air filters are of two types -- cabin type and intake air filters.
To drive at ultimate efficiency, automobiles require cleaner filters to avert waste product from entering fuel, engine or air conditioning systems. Particles can be the root cause for poor performance and abbreviate the lifespan of the automobile. Hence, routine inspection of the condition of the filters is vital. The replacement of these filters depends on many factors like automobile makers recommendation and the surroundings in which the filter operates.
Regulations associated with emission control to decrease air pollution worldwide is the main impact on automotive air filter market size. Europe has already amplified the use of materials used in automotive filters as a result of diesel and petrol standards regulating the light and heavy vehicles.
The manufacturing of air filters has thus gained momentum on account of the high aftermarket demand, because of the need to be changed at fixed intervals.
Advances in filtration technology include increase of continuous processes replacing long-standing batch process technology. Filtrations using conventional filters are chaotic and unsafe to clean and require extended re-circulation time to obtain a clean product. Now the traditional separation system such as disposable filters is being replaced by fiber filtration systems.
All the chemicals like alcohols, acetones and methylene chloride which are of aggressive nature are the most commonly used products and for that reason, the filtration system has to be accustomed to meet these requirements as well as the usual filtration.
Regulatory compliance, need to cut total lifecycle costs by enhancing process efficiency, focus on justifying health concerns by purifying air and controlling the potential effects of air pollution are the driving factors for the need of advancement.
Here are some examples of advancements in automotive filter technology:
The filter bags are meant to be operative in applications involving the recovery of powdery products and dust along with capturing color pigment dust. The pores and fibers allow pigments to be formed with small particle diameters. The filtration medium is free from silicone, makes the filters recover color pigments.
Nanofiber coatings are capable of separating very fine dust and smoke. These filter cartridges are easy to clean and require low maintenance.
Online monitoring for corrosively measurements
The online monitoring system provides reassurance against corrosive gases. The monitoring system also features corrosion sensors.
Purification and Pollution
Over the last few years, there has been a steadily increasing demand for improved air quality which must consist of the removal of unpleasant but harmless odors, but more essentially the removal of hazardous elements.
Controlling the possible effects of air pollution by as long as internal air filtration technology inside buildings, aircraft and vehicles that are used in unsafe surroundings.
Hydrogen sulfide removal
Hydrogen sulfide (H2S), commonly found in oil and gas pools, is a very toxic gas produced naturally in many industrial processes. This new cleaning technology expects the removal of pollutants from various gas streams. Then a catalytic mixture that converts H2S to solid sulfur is established.
