In the continually updated online report, Fabric Filter and Elements World Markets, the McIlvaine Company, Northfield, IL, predicts that revenues will increase at 6 percent per year over the next five years.
This huge growth rate is attributable to several factors. One is the switch from electrostatic precipitators to fabric filters. Power and cement plants are now required to achieve greater than 99 percent dust removal. The fabric filter is considered to be the most efficient device for particulate control. Thus it is selected more often as regulations are tightened.
Another factor is the rapid growth of heavy industry in Asia. Steel mills, foundries, chemical plants and cement producers are expanding throughout the region.
There are two distinct types of suppliers. One type makes small modular collectors used in light industry. Donaldson and Dantherm are examples in this category.
The other type makes larger custom designed collectors. Alstom and Siemens (Wheelabrator) are two of the leading suppliers of the custom design.
The filter media is the most important component of the filter. Typically, this media is sold in rolls to an element manufacturer who sews the media into tubular bags or pleats it into a cartridge.
Most of the media is made by global producers. Most of the elements are made by local suppliers with some exceptions. GE BHA and MFRI supply bags and cartridges from facilities located on several continents.
