Almost a century of combined experience in the recreational and commercial vehicle industry, along with aviation and automotive technology, led to the development of a 12 Volt, high performance air exchange system for recreational and commercial vehicles. The core of the system is a powerful 12 Inch, 10-blade rotary fan that works with a slightly open window to create a balanced airflow. It is designed for maximum air exchange, minimum sound levels and power consumption. Fresh, clean, natural air is pulled in. Hot, stale, stuffy air is pushed out. Fan-Tastic Vent will exchange the air in your vehicle in minutes. Cooking smoke and unpleasant aromas are whisked away in seconds. Fan-Tastic Vent can reduce the use of air conditioning allowing you to breath natural, fresh ambient outside air. Fan-Tastic Vent is light weight, compact, bug resistant, durable and seals tight when not in use. The sealed motor operates at variable or 3-speeds depending on the model for selected performance levels. Installs in minutes and fits the standard existing opening provided by most recreational vehicle manufacturers.
