The Downflow Series of reverse jet cleaning dust collector units offer a compact solution for medium to large duties and use the 328mm diameter ‘deep pleat’ cartridge technology.

Utilising a high-level inlet and the cartridges mounted in a horizontal format, the units offer enhanced cleaning capability due to the ‘down-flow’ air pattern and can be extremely effective on light and low bulk density dusts.

The units can also be offered with safe change filter element removal & product collection, and integral secondary HEPA filter sections.

This makes the range well suited for use with toxic dusts or where exposure to the operator and environment is strictly controlled (e.g. pharmaceutical applications).
