Most common filter bag fabrics

We offer a wide selection of filters for all your needs. Our filters are designed to meet the highest standards in terms of filtration efficiency, durability, and performance.

Polyester

Starting with polyester, this filter media is ideal for applications below 275 degrees Fahrenheit. It's a cost-effective option known for its resistance to abrasion and performance in dry conditions. Commonly used in industries like food manufacturing and agriculture.

Next up, aramid. This material can handle temperatures up to 400 degrees Fahrenheit, making it suitable for cement, metalworking, and foundry applications. Like polyester, aramid is abrasion-resistant, offering durability in demanding environments.

Moving on to fiberglass, a specialty media designed for temperatures exceeding 400 degrees Fahrenheit. It thrives in high-temperature and moist conditions, making it a top choice for industries such as chemicals, minerals, and energy utilities. Keep in mind there are other specialty medias out there.

Additionally, filter media can benefit from special treatments like PTFE coatings, which enhance efficiency, reduce wear on pulse valves, and decrease plant energy consumption. 

Plenum and pulse jet baghouses collect dust on the outside of the filter. Below is a general outline of the most common types of filter bag construction you would see for a pulse jet or plenum pulse dust collector.

• Flange Top
• Ring Top
• Sleeve Top
• Hem Top
• Raw Edge
• Disc Bottom Bags

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 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 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.

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.

What's the most effective filter media based on your application? To get the best performance and longevity out of your dust collector filters, start off by choosing the right media. Choosing media for your filters is going to be based on the type of application they will be used for. When you're looking at different options, take into consideration the following things:

• Product - what you are filtering?
• Particles - what the size of the dust you are filtering?
• Temperature - are you operating with extreme temperatures?
• Chemistry - does your filter need to withstand dust particles that have a chemical make-up?
• Resistance - what's the filter's ability to resist the wear and tear of dust?
