Accudraft KD™ air makeup systems are completely integrated intake, heat, and exhaust mechanicals in one. Available in both 500 and 560 models, the KD is designed for maximum efficiency. Intake and exhaust units are joined in the center by a recirculation unit that makes sure your booth's heated air stays in the system allowing you to cure jobs faster while costing you less by minimizing energy losses. Add Accudraft's EnergySmart™ VFD package to drop your energy costs down to almost half of what traditional spray booths cost you to operate. Depending on your state's policy on energy efficiency and VFD upgrades, you may recieve rebates that almost cover the entire cost of the upgrade!
