Ordinary bag-type dust collectors cannot meet the environmental protection requirements and must be modified to reduce the wind speed and increase the filter area of the dust collectors so as to meet the required emission standards. Pleated filter bag, also called star filter bag, is a new type of dust filter bag that can be applied to pulse bag filter. And there is a supporting dust removal framework. It is a cost-effective filtration solution that can significantly reduce costs and solve bag house capacity problems.
An innovative product from Philite®, the unique pleat design of the pleated filter bag doubles the usable fabric filter area in the same space compared to conventional cylindrical and oval filter bags. The pleats are gathered at snap-on straps at the top of the filter bag, so the pleated filter bag fits into the same cell plate holes as a standard bag of the same diameter. Horizontal bands sewn into the fabric ensure that the pleats are retained throughout its service life.

The use of pleated bags to retrofit existing precipitators eliminates the need to retrofit precipitator bodies and replaces existing bags and keels directly, increasing system filtration area by 50-150%, which is the best improvement program for improving the production efficiency and capacity of dedusting systems.
The use of wrinkled bag instead of ordinary round or oval bag can greatly increase the system filter area, can directly reduce the air-cloth ratio, significantly reduce the system pressure and pulse frequency, thereby significantly reducing the system’s dust emissions, especially ultra-fine dust emissions .
The use of wrinkled bag instead of ordinary round or oval bag, the pressure drop of the system is greatly reduced, the energy consumption of the fan is greatly reduced; the injection frequency is significantly reduced, and thus the compressed air usage is significantly reduced, and the loss of the injection system components is also greatly reduced.
The use of pleated bags instead of ordinary round or oval bags, the unique combination of filter bags and keel completely avoids the fatigue damage to the filter bags caused by the ordinary keel transverse support rings. Combined with the lower running pressure and blowing frequency, the bag fatigue damage is greatly reduced. , life expectancy is greatly extended.
The new dust collector uses a fold bag instead of an ordinary round or oval cloth bag. Under the same air-batch ratio, the dust collector box and pulse injection system can be greatly reduced, and the initial equipment investment of the injection system can be reduced while ensuring or improving the system efficiency. And floor area.
The cage of the pleated filter bag is different from the common cage, and a special cage is required due to the support requirements of pleated filter bags. A cage is an essential component in industrial filtration systems, particularly in baghouse dust collectors. Typically, it is made of metal (carbon steel, galvanized steel, or stainless steel) for durability and corrosion resistance. Learn more.
Pleated filter bags are commonly used for gas and liquid filtration in industrial and commercial applications. They are designed with a pleated structure that provides a larger filtration surface area, thereby increasing filtration efficiency and capacity.
