Powder filtration systems
Filter Press Dryers Dry Vac Environmental Rio Vista, CaM.
Powder Filtration Systems Columbus Industries Inc. Ashville, Ohio
DryVac vacuum filter press dryers economically process slurries and create solids cake with a corresponding 30 to 75% reduction in weight and volume. After initial pressure dewatering, water is vaporized from the cake by applying heat and vacuum to the cake while still inside the press. In typical metal hydroxide applications solids are removed and can be dried to 100% dry in about 4 hours. Custom-designed systems are available.
Columbus Industries has powder filtration systems specifically designed for highest particulate removal efficiency, high holding capacity, or a combination of these performance characteristics, creating a tailored collection system to fit specific filtration goals. Many of these systems are well suited for combined liquid paint/ powder paint duty where coatings are sprayed interchangeably. These collectors include paper and polyester media in cut-pad or roll form, extended-surface, dualand multipocket, and cube units with a range of efficiencies. Dual-pocket collectors like Columbus Industries' SL-45B achieve very high particulate arrestance, while operating at a low restriction to airflow. The SL-45B would be used as a secondary-stage filter behind less expensive flat collectors.

Filter Housing Lufran Streetsboro, Ohio Lufran offers a machined PTFE high-temperature filter housing for use on all SOE 10-in. style filters, as an alternative to disposable-type filter housings. The Lufran PTFE machined housing can be used on all standard SOE 10- and 12-in. filters. Typical applications include phosphoric and sulfuric. Filter housing life is substantially increased due to the use of Teflon rod stock and thick wall construction.
