SIGNIFICANT AIR SPREAD AREA : Area covered up to the extent one can feel the air velocity, as equivalent to moving through 1/2 kilometer every hour, at a height of 150 cm. below the plane of fan blades.

To test this hypothesis, our design engineers developed a prototype. After extensive tests and further improvements, the hypothesis became fact when the prototype proved successful. The breakthrough has been achieved. To manufacture the prototype on a commercial scale, our factory had to be extensively restructured. New moulds and dies had to be created. Alloy compositions were changed. The work force had to re-oriented. An amalgam of all these factors is behind the creation of PSPO.
