SDB downdraft-bench dust collector
Designed for applications where workers need an integrated collection area and work surface, the SDB downdraft-bench dust collector features a powerful downdraft velocity of 100 ft/m and air volumes up to 2,500 ft3/m. The SDB captures smoke, dust and powders that result from manufacturing operations including grinding and polishing. By drawing particles and contaminants away from the worker’s breathing zone, the SDB protects employees and helps manufacturers to comply with OSHA regulations. The SDB has an 80-in. by 55-in. grated work surface capable of accommodating loads of up to 75 lb/ft2. Hinged side wings open to accommodate larger work pieces and uniform air distribution maintains superior dust control over the whole work area. The system automatically self-cleans when pulses of compressed air dislodge dust from the filters upon shutdown. High capacity, lightweight dust drawers allow for longer periods of uninterrupted operation before they must be emptied. No tools are required for manual inspection or emptying or changing filters and collection drawers. Its pressure gauge indicates when filters require replacement. The system is fully-assembled prior to delivery, and has a powder-coated finish to prevent fading, chalking and corrosion. Its simple installation requires only an electrical collection and compressed air for in-place cleaning. The collector features a 3-hp motor and 230–460/3/60 voltage.

Dust Collection Cartridge Filters
These dust collection cartridge filters feature an advanced nanofiber filtration technology that allows them to last twice as long as cellulose and 80/20 commodity filters. The novel technology allows advancements in surface loading capabilities, including a surface treatment of synthetic nanofibers, which forms a nanoscopic mesh to trap dust particles on the filter’s surface. The particles are released easily during the cleaning cycle and lower the pressure drop over the life of the filter. Dust collection systems equipped with these filters may use up to 60% less compressed air and require less energy to operate. They are certified to collect submicronic dust particles at MERV 15 efficiency levels. These filters can reduce emissions by 50% or more over standard cellulose filters, provide a cleaner breathing zone for workers, and minimize facility maintenance.

Advanced Nanofiber Filtration Technology
Advanced Nanofiber Filtration Technology for dust-collection cartridge filters helps reduce emissions by 50% or more over standard cellulose filters, providing a cleaner breathing zone for workers and reducing facility maintenance. It features advanced surface-loading capabilities that result from a mesh of 70–150-nm fibers that trap dust particles on the filter’s surface, where they are easily released during the cleaning cycle. Dust-collection systems equipped with these filters have lower pressure drops than standard cellulose filters, and they may use up to 60% less compressed air and require less energy to operate.
