The SV-D12 silo vacuum by Ruwac is a ultra-rugged, heavy duty vacuum designed for continuous operation and geared toward point of source extraction. Unlike it’s portable counterpart the DS1220, this vacuum is stationary and attaches to a 30 gal. drum for increased collection capabilities. The SV-D12 silo is grounded and sealed, contains a 3 HP TEFC motor and features a 180 CFM complimented by 13 sq. ft. of Ruwac’s industry-leading MicroClean filtration with the option to upgrade to HEPA or ULPA filtration, making this vacuum easy to maintain.
