MAC Air 2-Person Helmet Air Pumper (Bundle) is designed to keep users cool, eliminate dust, and promote comfort. Ideal for desert racing, dune cruising, or short course track, this pumper is built with an injection-molded ABS polymer housing for amplified airflow. Its high static pressure fan makes it produce more pressure and volume than other available pumpers. A dual filtering system heightens performance, prevents early clogging, and filters dust and debris through uniform micro openings before reaching the internal filter. Both filters can be cleaned with water post-race. With an inclusive VSC (Variable Speed Controller) you can access and adjust the pumper's airflow volume more easily. The MAC Air bundle comes with two super lightweight expandable pumper hoses, a washable dry media air pre-filter, a foam intermediate filter, a particulate pre-filter wrap, a high duty cycle life motor, a waterproof power connector, and a 12' power cord. It includes a Universal Bar Mount and is built to race.
