One of the most overlooked details in maintaining a baghouse is seals. Baghouses operate on a suction system with the fan placed after the collector, that pulls air through the system and into the baghouse for filtration. The system’s mechanics relies on air pressure, with air only flowing from three main points into the collector: the pickup point, duct-run, and inlet duct. Any additional air leaks in the system’s configuration cause pressure loss, creating issues in the equipment’s ability to filter the gas stream. Air leaks also introduce moisture and humidity, which change the atmosphere’s chemistry and can cause corrosion and bag blinding.
Tight seals throughout the baghouse are critical to the filtration system’s performance. Unfortunately, most baghouse door seals are made from rubber, which becomes brittle and cracks due to high operating temperatures and chemical attacks. As a result, rubber seals are a high-maintenance item, slowly consuming the producer’s bottom line. Simple and easy to install, Albarrie’s AlSeal™ Baghouse Door Seal is designed with Nomex ® fabric to stop air leaks, create system efficiency, and save money. AlSeal™ door seal works in all baghouses with access door ambient temperatures up to 400°F (200°C).
