Polyester Filter Bags
Polyester filter bags are one of the most widely used filter bags in industrial dust collection applications. They are constructed using high-quality polyester fabric, which provides robustness and dimensional stability. As a filtration media, polyester has the following characteristics:
-
Filtration Efficiency - The tight polyester fabric structure traps even the smallest particles, ensuring a high level of filtration efficiency. This makes polyester filter bags particularly effective in removing fine particles and dust from dust-laden gas.
-
Excellent Tensile Strength and Abrasion Resistance - This allows them to withstand high-flow rates and pressure differentials without tearing or disintegrating.
-
Excellent Mechanical & Dimensional Stability - Polyester filter bags are dimensionally stable and have low shrinkage properties. This ensures that they maintain their shape and size even under high-temperature conditions.
- Easy Cleaning - Polyester filter bags can be easily cleaned and reused, reducing the need for frequent replacements and minimizing waste.
In addition to these filtration characteristics, polyester filter bags also offer a number of other advantages, such as:
- Long Service Life - The durability of polyester filter bags results in longer service life, reducing the need for frequent bag replacements.
- Easy Maintenance - Polyester filter bags are easy to clean and maintain, allowing for efficient and convenient filter bag cleaning processes with minimum maintenance costs.
- Versatility - Polyester filter bags are available in various sizes, shapes, and configurations, making them suitable for a wide range of industrial filtration applications.
- Cost Effective - Polyester filter bags are relatively affordable compared to other filter bag materials, making them a cost-effective choice for filtration applications.
Scrim-supported felt is used exclusively in the production of our polyester filter bags in order to improve filtration efficiency and extend the filter bag life.
Dust Collection Characteristics
Polyester filter bag is relatively low-cost and widely available. In addition, it has good overall qualities to resist abrasion and perform well under dry conditions. Therefore, it is a general-purpose baghouse filter media commonly used in a variety of industries.
