• 99.99% efficiency
• Higher airflow
• Better cleaning
• Optimum emissions control
Media. Size. Construction. A lot of careful consideration goes into choosing the ideal filter for your dust collector. That’s where we come in. Our global team of industry specialists has decades of experience in the application of ePTFE membrane filter bags across a wide variety of industries. We’ll help you evaluate your options and select the right filtration solution that can help you improve operations and optimize baghouse performance.
It’s not just the quality of the membranes we make that sets us apart—it’s what we do to them. Using our core competencies in membrane extrusion, lamination and finishing treatments, we design BHA Preveil membrane filter bags to improve filtration efficiency and operate at consistently low
differential pressures. This helps reduce filter changeouts and energy costs, extends filter service life, and can help lower particulate emissions across a wide range of applications.
