The INTEWA MD-100 and MD-150 wall bushes are specially developed for rainwater harvesting. Inserted into walls, they prevent cold, damp and backwater from permeating the ductwork into the control unit installation room by sealing the pipework and electrical cabling. They feature different size holes to take both intake pressure hoses and electrical cables through walls to the control unit. Unused holes in the bushes are sealed with blind plugs. Bushes are made of stainless steel and a high quality rubber compound and are easily installed and tightened in place even if retrofitted.
