Low Temp Filter Bag Media Guide

Top 3 Low Temp Filter Bag Media

If your plant is operating from ambient to 275 degrees Fahrenheit, there are a few low temp filter media bag options you can choose to use in your dust collection system. To guide you to the right one, we’ve gathered information on the three commonly used medias in low temperature dust collection applications. The following filter medias are generally for dry dust applications with very little moisture and no issue heats or acids.

Polyester

Polyester is one of the most economical low temp filter bag medias used in the dust collection industry because of its reliable performance in a broad range of applications and availability. This media is used in industries including food manufacturing, woodworking, metalworking, building products, and energy. Polyester is one option if you are continuously operating between ambient – 275 degrees Fahrenheit, and have less than 10% moisture.

Polypropylene

Polypropylene is another relatively low-cost, low temp filter bag media. The big difference between polyester and polypropylene is that polypropylene can withstand some moisture. If your continuous operating temperatures are between ambient – 170 degrees Fahrenheit, and you have more than 10% moisture in your application, then Polypropylene could be the right fit for your baghouse.

Acrylic

Another option for applications with more than 10% moisture is Acrylic. This is similar to polypropylene but more expensive. Acrylic can handle moisture better than polyester and has a higher temperature rating. If you need to run between 200-265 degrees Fahrenheit, but you have moisture, you could use acrylic.
