The Starbottom is an advanced filter enhancement for Pleated bag filters and Filter cartridges that optimizes dust release in critical applications. The star effect at the bottom of the filter ensures that dust is efficiently released into the receiving hopper, preventing build-up at the bottom end cap.
This technology is particularly beneficial for food applications and applications in potentially explosive environments. Combined with Weltech technology, Starbottom technology offers exceptional durability and versatility.

Comparison of Starbottom Design and Standard Bottom End Cap in Dust Extraction Filters
In industrial applications, dust extraction filters are essential to ensure clean air and efficient operation. This comparison highlights the differences between the innovative Starbottom design and the conventional standard lower end cap. The focus is on dust release efficiency, maintenance and operating costs.
Starbottom design
The Starbottom design features an open, folded media at the bottom, allowing dust to be easily released into the collection container. This open structure prevents dust accumulation at the bottom end cap, optimizing the performance of the filter. By releasing dust efficiently, the Starbottom design ensures a lower pressure drop, reducing energy costs and extending filter life. Combined with Weltech technology, it offers improved durability and is suitable for various industrial applications. It also meets stringent food and ATEX standards, providing a reliable and compliant solution.
Normal bottom end cap
In contrast, the normal bottom end cap covers the pleated filter medium and closes the bottom of the filter. This design leads to dust accumulation as the dust cannot be released efficiently. The accumulation of dust increases the pressure drop, which leads to higher energy costs and reduces the overall efficiency of the filter. In addition, the frequent accumulation of dust requires more frequent maintenance intervals, resulting in longer downtimes and higher costs. While the normal bottom end cap design is widely used, it poses a challenge to maintaining optimal performance and cost efficiency in dust extraction filters.
