Introducing RTR HD. When you are hard at work- airflow is the key to staying comfortable and focused on the task at hand. Beyond comfort, powerful airflow can prevent the buildup of fumes, direct air into and out of workspaces, and dry wet paint and floors. A powerful fan is certainly more than comfort it is a tool of the trade. The 270 deg. tilt means you can focus RTR HD's ample power downward to dry wet floors or upwards to promote airflow that dries paint or other finishes.
