CNG/LPG sweepers clean the environment
Alternative-fuel Regenerative Air Sweepers use Compressed Natural Gas (CNG) or Liquified Petroleum Gas (LPG) for clean operation. Brushless, floating pickup head adjusts to irregularities of paved surfaces to vacuum up dust, dirt, silt, stones, and packed-on debris, even in wet conditions. Air-tight closed loop directs all debris into hopper where fine particles are removed by a centrifugal dust separator, then cleaned air blasts surface again. System has no baffles or filters to repair or replace. Low-emission vehicles help entities meet municipal, state, and federal requirements for environmentally friendly AFV fleets.
