The unique shape of the spirotube provides excellent dust collection with a very low-pressure drop. The different diameters of the STS spirotubes provide an optimal relationship between the total unit area and the open area between the tubes. This decreases face velocities and increases airflow in four directions between the elements, enabling better control of the airstream velocities and increased dust release capacities.

Benefits

• Low pressure drop, even at high air-to-cloth ratios
• Very low emissions of less than 1.0 mg/Nm³ due to the 99.99+% efficiency of the expanded microporous structure of the BHA-TEX membrane
• Excellent dust release characteristics resulting in increased airflow and reduced differential pressure
• One-piece design eliminates the need for support cages
• Snap-in fit reduces installation time
• Spirotubes can be replaced individually, reducing costs

STS filter elements can be used in new installations or as replacements for existing installations with sintered filter elements or various envelope type filters.
