    FAQs About DNA Filters

    The DNA Air Flow Tests

    For the air flow tests, we use the most advanced flow bench available today. The ROTRONICS FlowScan, is a totally computerized flow bench that measures:

    • Mass of the air
    • Flow of the air
    • Temperature of the air
    • Absolute air pressure
    • Differential air pressure
    • Speed of the air at various points (Pit ot tubes)
    • Absolute humidity of the air


    The complete procedure is automated and computer controlled, eliminating human errors.

    The DNA Dyno Tests

    For the Dyno Tests, we use the industry standard Dynojet chassis dyno equipped with eddy current load control, Dynojet 250LC. Our dyno cell is equipped with a variable flow air cooling system, designed to precisely simulate real world conditions.
