The R300TGDD + EVAC Wall Section allows for the placement of Paddock’s Evacuator along with integral deck drains that can be added to any perimeter. Paddock’s Evacuator restricts noxious air on a pool’s surface and pushes room air towards the pool without disturbing it’s surface. With this in-gutter option, the Paddock Evacuator can be retrofitted and tailored to your natatorium’s specific needs.
