Our vibrantly colored cold air balloons are stationary and are not adversely affected by inclement weather. They can withstand winds up to 40 miles per hour when properly installed. The blower for inflating these balloons operates on either 110 or 220 volts. There is no danger of heat, flames or gases. All units are supplied with a quarts - halogen internal light system. The superior quality material used to manufacture our custom inflatables is a fire retardant, 7 ounce, two sided, vinyl coated nylon.
