HIGH PERFORMANCE Filter Kit for MAC Air Helmet Pumper

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.
