The V-5000 is a 5-hp dust collector with a Baldor motor and a backward-inclined fan wheel. According to manufacturer Oneida Air Systems, the V-cyclone design is highly efficient at ultra-fine dust separation, greatly reducing the need for frequent filter cleaning. The GE H12-certified HEPA media filter is said to guarantee 99.97% from 0.3-0.5 micron filtration. An internal silencer quiets the unit to 81 dBA @ 10 ft. The maker reports the V-5000 can be set up quickly in a small footprint. (800) 732-4065, Oneida-Air.com.
