Dyna Products/Vortex

The Vortex V18-32 drum chipper, with its 18×32 opening, has more capacity than other chippers in the 18-inch class. Hand fed or machine fed, the ‘oversized- opening makes feeding and operating best in class. The V18-32 can process limbs and even small whole trees. The patented Vortex chamber is an enclosed, semi-cone shaped area that acts as the bellypan where chips are guided and accelerated into the discharge paddles. Gravity and powerful air currents generated by the spinning drum and impeller assembly create an unrestricted pathway for chips to naturally flow directly toward the discharge paddles. The chamber virtually eliminates plugging and controls dust and ‘blowback.’ Diesel and gas engine options range from 173 to 247 hp. Covered by a 36-month, 3,000-hour limited warranty. www.dyna-products.com
