The SRS line of blowers were designed over 15 years ago when the need was recognized for a high performance brake cooling blower to replace the small boat bilge blowers that were currently being used. The SRS was the first blower to arrive on the market specifically for racing with the performance needed for the job. The SRS800 is the latest version and replaces all previous versions including the SRS400 and SRS500. These are no longer available. The SRS800 is an evolution with better performance, is significantly smaller, lighter and draws less current than any previous model.
