Dust Control Technology has introduced a 180-degree oscillation option for its DustBoss DB-60 model. According to the company, the new feature will allow effective particle control over more than 80,000 square feet of area from a single location. Other features include: revised designs require that engineers change to a center water feed to accommodate the increased range of motion; larger motor must be installed on the DB-60 or its cousin, the DB-45, to handle the additional work; machines will have four different settings, with 45-, 90-, 135-and 180-degree oscillation options.
