Webasto’s HFT 300 and HFT 600 Air Cleaners are lightweight, compact cylindrical units that use medical-grade HEPA-14 filtration media and can be installed almost anywhere inside vehicles. With their high-velocity twin-axial fan motors, the high-efficiency air cleaners have rapid air exchange rates. The HFT 300 is engineered to deliver up to 5 cubic meters of purified air per minute or 300 cubic meters per hour, and the HFT 600 is built to process and clean up to 10 cubic meters of air per minute or 600 cubic meters per hour. The filters are designed to allow both air cleaners to remove 99.995% of airborne particles equal to or greater than 0.3 microns. A single intake port is located on one end of the unit, and decontaminated air is released in all directions around its circumference. Each unit’s filter monitoring feature senses when its filter needs to be changed, and an LED light alerts users when it’s time for maintenance. The air cleaners have integrated mounting brackets and are designed for ease of retrofitting. Both are compatible with 12- and 24-volt electrical systems and are available with optional wire harness kits.
