Our 4-yard stationary compactor is perfect for businesses producing waste that is large and bulky. The A-4 compacts waste into a 40-yard container quietly and efficiently. Like all Ace Equipment compactors, interlocking structural stiffeners guarantee structural failure is impossible. Hydraulic components are chosen by quality, not price, ensuring little to no down time throughout the life of the compactor. To back this up we provide the best warranty in the business.
