Pleated bag cartridges

Star bottom pleated bag

An alternative to filter bags.

Hengst offers a unique option for food production facilities with FDA compliant requirements in combination with star bottom design. Top or bottom loader with star bottom, or as we call it FPBG or FBLPBG, is EC 1935:2004 certified which secures food safety and quality. At the same time, it complies with the hygiene standards currently used on the market.

An optimized dust release function is provided by using the star-effect in the bottom part of the filter, ensuring that the dust is released from the filter into the hopper without being trapped on the bottom cap. This function makes the usage of pleated bags in food- and ATEX applications even more suitable.

The star bottom solution combined with our Weltech technology and EC1935 certification provides you the optimal solution for a durable multi-functional pleated bag which is suitable for your food production.

Suitable for:

  • Cement

  • Powder coating
  • Laser cutting
  • Sand blasting
