Exhaust air discharges from the side of the Razaire 530. This adapter slips down over the exhaust, re-directing the air towards the back of the unit. Useful in classes, but itʼs also great to re-direct air in many other situations e.g. when using your Razaire 530 beside a tabletop sander or scrollsaw. It is also recommended that you use this deflector when using a Razaire 530 without the front hood.
