Islandaire EZ Series 45 is a replacement for the American Standard Carteret Remington and Singer models of Type 45 units. Our commercial duty construction with heavy gauge galvanized steel and superior components create an efficient reliable unit.This design eliminates the need for any interior or exterior renovation. Use of the existing wall sleeve-cabinet and louver saves time and money, two very important factors in today’s competitive environment! If the need does occur where the wall sleeve-cabinet and/or louver needs to be replaced, we manufacture these accessories as well.
