The one-piece, self-supporting spirotubes are made of spun bonded polyester media laminated with BHA-TEX® expanded PTFE membrane. The STS spirotubes seams are thermally bonded to ensure airtight construction.

STS elements replace expensive, fragile, low-surface area, sintered plastic filter elements. The unique shape of the spirotube provides the best possible 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.

• 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

• STS filter elements can be used in new installations or as replacements for existing installations with sintered filter elements or various envelope type filters.
• Replacement costs are reduced since individual spirotubes can be replaced without replacement of the remaining elements.

Applications
