Spiral Tube Mist Collector

Spiral Tube Mist Collectors

The Spiral Tube Mist Collector is a two-stage mist collector that uses spiral tubes to provide a high level of mist agglomeration and removal without using filters. Centrifugal force and impaction provide the mechanism for primary oil mist removal. Stainless steel separation tubes provide lower lifetime maintenance costs than filter bags which must be periodically replaced.
