As production managers and service technicians strive to improve the performance of their dust collectors and filtration systems, the introduction of innovative filtration technologies is of paramount importance. Switching from traditional filter bags to Pleated bag filters can solve critical issues by reducing maintenance and optimizing overall system performance. This article looks at the reasons that motivate operators to upgrade their existing systems, compares pleated bag filters with conventional filter bags and highlights the differences.

Operators are constantly looking for ways to improve the performance of dust collectors. The most important factors are reducing the total cost of ownership (TCO) and complying with environmental regulations. Filter technologies such as pleated bag filters have proven to be a solution to these challenges. They offer better performance and reliability compared to conventional bag filters by lowering energy consumption, minimizing emissions and reducing maintenance costs.

The filtration concept of pleated bag filters differs significantly from that of conventional filter bags. Due to the surface filtration, a different filtration method is used at pleated bag filters, which offers advantages over conventional bag filters in many applications (see Benefits of pleated bag filters). The table shows the most important differences between conventional bag filters and pleated bag filters from Hengst Filtration.

Pleated filter bags are available in a variety of Filter media and Executions and are suitable for a wide range of industrial applications. This adaptability ensures that in environments with high temperatures, corrosive environments or fine dust particles, there is a suitable pleated bag filter to meet the specific requirements of the operation. This makes pleated bag filters an ideal solution for various industries such as pharmaceuticals, food processing and metalworking

In many cases, pleated filter bags are shorter and have a larger filter area (see illustration below), while providing the same or higher performance. This can result in longer life, lower energy consumption and higher capacity.

Excellent dust release and performance of pleated bag filters

Unique spunbond filter media promotes surface filtration, resulting in excellent cleanability and stable differential pressure throughout the service life. In addition, the Starbottom technology further improves cleanability and service life by preventing dust build-up and accumulation. This reduces the risk of abrasion and ensures a longer service life.

Versatile application of pleated bag filters

The use of pleated bag filters is extremely versatile. The filters can be fitted with a range of media that provide reliable filtration performance under a variety of process conditions. Our pleated bag filter are designed for various dust types and particle sizes and can be used in different chemical environments. We also offer Filter media and Designs , which can be used at temperatures of up to 200 °C. With pleated bag filters, you can also equip your processes for future dust emission regulations of 10 mg/m3.

Long service life and proven performance of pleated bag filters

Pleated bag filters can reduce downtime and maintenance costs as well as energy consumption. The pleated filter medium reduces the length compared to a conventional bag filter with the same filter area. Installed in a dust collector, the pleated bag filter is located outside the abrasion path, resulting in a lower risk of abrasion and a longer service life. With filter improvements, such as our Weltech technology, our pleated bag filters can be improved in terms of stability and robustness.

Capacity improvement with pleated bag filters

With pleated bag filters the capacity can be increased without having to significantly change your filter system and make additional investments (CAPEX). The reason for this lies in the design of the pleated filter bags. Their pleated media structure increases the filtration surface compared to a filter bag of the same length. A pleated filter bag can provide a filtration area 2-4 times larger than conventional bag filters. Therefore, a pleated bag filter can be a solution if you want to expand the capacity of your filter system.

In summary, Hengst Filtration offers an extensive range of pleated bag filters to meet a wide variety of industrial requirements.
