HIGH PERFORMANCE Filter Kit for MAC Air Helmet Pumper is designed for severe dust, dirt, and ultra fine silt particulates, providing the ultimate in filtration. A three-stage defense against dust, dirt, and silt, the kit includes a non-washable and non-reusable micron paper filter, along with a washable intermediate foam filter and pre-filter. It contains 6.5 feet of filtering media, which is 18% more than conventional filters. Deep pleats trap particles, heavy-grade interior wire mesh blocks larger particles, and an open cell intermediate foam filter provides additional protection. An outer micron pre-filter prevents most particulates from interrupting airflow. These extend the life of your paper filter.
