The E ZEE DRI Tennis Court Dryer is a machine designed to dry hard tennis courts to expedite play after a rain delay. Drying a tennis court has never been easier. Three primary functions (suction, blowing, and heating) work together so play can resume more rapidly. The E ZEE DRI Tennis Court Dryer is better than a rol-dri or squeegee and superior to any blowers on the market. It is a quicker, cleaner alternative for hard court drying.
