202 to an appropriate pulley of the blower 210 as shown in fig9 the blower 210 disposed within and secured to the blower housing 50 is preferably of the squirrel cage type as discussed above the rotation of the vanes of the blower 210 cause air to flow through the pad 150 from outside the evaporative cooler apparatus 210 and into the blower housing 50 through the aperture 64 shown in fig9 and through another mating and aligned aperture on the wall 54 not shown opposite and parallel to the opening or aperture 64 in the wall 58 the air then flows downwardly through the opening or duct 46 and into an appropriate distribution system such as a ductwork or directly into the structure water for saturating the pad 150 is provided by a water supply line 220 which is secured to the circular cylindrical wall 16 of the base 12 control of the water from the water supply line 220 is through a float and valve assembly 222 the float and valve assembly 222 is of course appropriately connected to the supply line 220 through the wall 16 in operation water flows into the base 12 until it reaches a predetermined height the float and valve assembly 222 maintains the height of the water in the base 12 at a relatively constant level if for.
