A filtration system includes a rotary drum and a media holding band that is configured to hold a filtration media on an outer surface of the rotary drum. The media holding band includes a strap and a connector. The strap includes a first end and a second end opposite the first end. The connector is configured to secure the first end of the strap relative to the second end of the strap.

A regenerative filter having a length of filter material, first and second perforated filter supports, a filter regenerator, and an intermediate duct, a first end of the filter material being wound around the first perforated filter support to form a first scroll type filter through which air to be filtered can pass, a second end of the filter material being wound around the second perforated filter support to form a second scroll type filter through which air to be filtered can pass, the filter material is movable in both directions between the first and second perforated filter supports by passing a single layer of filter material through the filter regenerator as it moves between them, the intermediate duct being arranged to take airflow which has passed through the first scroll type filter to the second scroll type filter for filtration during use of the regenerative filter.

The present invention relates to a regenerative filter comprising, a length of material having a first support tail and a filter portion, a first end of the material being wound around a first perforated support to form a first scroll type filter through which air to be filtered can pass, and a second end of the material being fixed to a filter support, the regenerative filter being arranged such that the material is movable in both directions between the first perforated support and the filter support, passing through a filter regenerator generator as it moves between them, the first end of the material forms the first support tail which extends from the first perforated support to at least the filter regenerator when the material is unwound from the first perforated support, the first support tail having a more open structure than the structure of the filter portion.
