Can Bunnings supply a large evaporative air cooler (that is fitted into the side of the house- I can arrange that part of the fitting) and capable of cooling the entire area of an open plan house. Ive seen them In Quilpie. they have 3 side panels filled with a straw type substance that are kept wet with a pump pushing water up and over them.. The ones I saw had a drum style fan but Im open to a blade fan... Any ideas or suggestions? Thank you
