The Phat family offers premium products for air ventilation and filtration along with fan noise/air noise suppression. Phat Fans are high-quality in-line mixed-flow fans capable of medium to high static pressure. This line of fans features aerodynamically optimized airflow, quiet operation, and extremely high efficiency. Their included stable mounting brackets assure easy installation. Our Phat filters use proven odor-killing technology. They are packed full of high-adsorption-yield, high-density virgin carbon—the very best carbon on the market. The quantity of the carbon plays a role just as the quality does, and the carbon bed in Phat Filters is a true (not rounded up) 2 inches thick, providing more carbon for extended filter life.
