Increase in the demand for energy-effective, high-performing products is anticipated to propel the demand for air filtration. Developments in technology are leading towards the manufacturing of novel filter media coming across the demand for energy-effective products. Therefore, it has initiated the growth of inventive raw materials like small fibers projected to offer growth avenues for various industries. The change in the focus of legislation of US and Europe are considering to attend to the climate change issues and drive the inventions of air filtration to meet the target of energy efficacy along with the need for fine level of separation.

Efficient Energy against finer separation

In the gas and air filtration applications, the drop in pressure in the process steam flows through filter representing the energy loss made by the complete system leading to the energy cost. The greater the drop in pressure, or delta pressure, the greater the requirement of energy for separation and filtration system.

This is specifically correct in the applications of large volume like gas turbine process exhaust or air intake, dust collection systems on industrial applications. Moreover, the economic allegations of the energy loss is strengthening the legislative pressure across the globe on industrial activities for using less energy. In the scenario of filtration, the effort towards the effective use of energy opposes the important driving force for providing the growing degrees of separation for fulfilling the developed industrial processes. The challenging demands are not reconciled easily as filters are separating more effectively having the required high pressure drops.

Activity of research and development is driven by the judicial changes considered in place by the emerged regions in attempt to alleviate the effects of climate change by decreasing the emission of greenhouse gases. For instance, in Europe, UK government has defined the constitutional target for decreasing the emissions of carbon dioxide by almost 25% by the year 2021, on the basis of 1990 levels and reduction of the GHG emissions by almost 82%.

In the European lead, the Obama Administration in US took step in reducing the US oil consumption by 30%, with the related anticipated decrease in GHG emissions in the past. On considering the Deepwater Horizon incident and oil spill, and the subsequent environmental changes the Gulf of Mexico assured to drive through the moratorium on the offshore drilling. Impacts of oil spill are huge and are probable to escalate the speed of change in US oil reduction target and fuel the measures of energy reduction, specifically in automotive industry.

Automotive Filtration

Vose and Hollingsworth Company, filter media manufacturer and developer, has considered new families of automotive air induction products, Nanoweb media and Capaceon media, particularly addressing the increasing need for advanced unit filtration capacity and developed efficacy at low media delta pressure.

Capaceon is the new category of high-performance automotive air filter media maintaining the media cost of ownership in breaking the conventional link in the performance of media and basic weight. Hollingsworth & Vose entitles that the solvent-based and water-based versions of Capaceon media providing the capacity of dust-holding and enhanced primary efficacy at similar basis weights associated to the current media utilized in market. This generates the demand for consumers by providing high level of engine protection and long service interval.

To fulfil the requirements of recognized GHG reduction, the new vehicles will efficientlyclean the environment, essentially releasing the particulate concentrations in exhaust gases present in air intake. Main medium and the heavy-duty truck filter producers are choosing the Vose and Hollingsworth Nanoweb media in filters in demonstrating the technology for enhancing the protection of equipment, increases the filter service intervals and the less filter delta pressure than the standard media. NANOWEB media delivers the less primary pressure drop and high fractional efficacy. NANOWEB media is durable for filtering the ultrafine particles, such as dust, resistant to clogging, substantially enhances the service life. The complete cost of ownership is reduced which is directly contributing in achieving the environmental guidelines.

Many of the vehicles are using the Mass Air Flow (MAF) sensor yields to enhance engine combustion and observe the fuel economy and regulation of emissions. Solvent-based NANOWEB media for the application of automotive air are particularly designed for the displacement of engine, applications of light-duty where oil is added to filter media to fulfill the requirements. Constructing NANOWEB media in the filter applications are removing the requirement for oil by developing the element service intervals. Hollingsworth & Vose are providing NANOWEB media designed for off-road and on-road heavy duty air filter applications for the large gauge gas turbine & the systems of dust collections.

Industrial Filtration

The most common form of gas or air filter are the ‘bag’ filter or cylindrical cartridge and the ‘flat’ panel filter attached in the plenum chamber or dividing wall. The systems of flat panel are inclined to be utilized in the HVAC (heating, ventilation and air conditioning) systems in industrial and commercial applications.

Bag filters are mostly used in the industrial air filtration systems on large scale. The bad or cylindrical cartridge is situated in the cylindrical housing, series forming ‘baghouse’ system. The air flow is mostly caused through the bag from outside, separating solids that are accumulated outside which can be blown by the reverse pulse of compressed air. Even though giving way to nonwoven media, woven fabrics have an important role to play in baghouse due to its potential to flex while the reverse pulse.

Donaldson, prominent across the globe provides the filtration system and the spare parts, introduced by Synteq XP compressed air filter media where company enhances the efficacy while lessening the energy consumption because of low media delta pressure, accomplishing energy savings up to 50%.

Donaldson entitles that the consumers can protect ‘3 to 4 figure Euro sum’ on the energy costs per year. On the other hand, servicing and assembly is simplified with the help of specially designed filter housings. The potential of saving is established by PowerCore dust collection technology, where it is claimed by Donaldson that it is better for conventional bag filter units and results in significant reductions in operating costs.

Donaldson has the potential to transfer experience of air filter design for heavy duty vehicles to the advancement of the dust collection technology of company. PowerCore filter packs are associating the developed filter manufacturing techniques with Ultra-Web nanofibre technology. The high surface filtration performance is associated with the patented pulse cleaning technology resulting in the increase in performance.

Conclusion

Many of the recent developments in the filtration technology are depending on the new developments in media technology and filter design, fueled by the legislative responses to climate change and enhancing the GHG emissions. Inventive filtration products are permitting the filtration system designers and the plant managers to reduce the cost of operating and appreciate the cost savings of energy while fulfilling the quality standards in obtaining the increase in performance. Several developments in air filtration technologies for industrial applications, involving the inventions like NANOWEB, Capaceon, Ultra-Web technologies and PowerCore.
