The MBW 20" X 22" Compaction Plate Asphalt AP2000AH is the only vibratory plate compactor specifically designed for asphalt applications. Frequency amplitude centrifugal force and mass are all established at optimal levels for maximum productivity on asphalt. Further the mechanical construction of the AP2000 is specific to this very demanding application. Stress relieved steel plate housings are crack resistant and provide long wear. Aluminum exciter housing dissipates heat rapidly and custom lubricants preserve bearing and seal integrity. The self cleaning plate prevents dirt build-up.
