Abstract

A misting fan system includes a fan and a mister positioned above the fan. The fan includes a motor and a plurality of fan blades operably coupled thereto. Each of the fan blades comprises a base member and a paddle member mated to the base member, and each paddle member comprises an upper surface and a lower surface. A hydrophobic coating may be applied to at least one of the upper surface and the lower surface of the paddle member of at least one of the plurality of fan blades.

First claim

We claim:

1 . A misting fan system comprising:
a fan including a motor and a plurality of fan blades operably coupled thereto, each of the fan blades comprising a base member and a paddle member mated to the base member, each paddle member comprising an upper surface and a lower surface; a hydrophobic coating applied to at least one of the upper surface and the lower surface of the paddle member of at least one of the plurality of fan blades; and a mister positioned above the fan.

2 . The misting fan system of claim 1 , wherein the hydrophobic coating is UV resistant.

3 . The misting fan system of claim 1 , wherein each of the paddle members is made of plastic.

4 . The misting fan system of claim 1 , further comprising a support shaft connected to the fan for supporting the fan above a ground surface, wherein the mister is coupled to the support shaft.

5 . The misting fan system of claim 1 , wherein the mister comprises:
a housing that is substantially circular; and a manifold assembly disposed within the housing, the manifold assembly comprising an inlet for a pressurized liquid, wherein the inlet is in fluid communication with a fluid source.

6 . The misting fan system of claim 5 , wherein the mister further comprises a plurality of nozzles disposed within the housing and radially spaced apart from each other, wherein each of the plurality of nozzles is in fluid communication with the manifold assembly and includes an orifice for spraying the pressurized liquid outwardly from the manifold assembly, and wherein the housing further includes a plurality of holes formed in an outer wall thereof for allowing the pressurized liquid to spray outwardly from the housing;
wherein each of the plurality of nozzles is at least partially disposed within the outer wall of the housing; wherein the manifold assembly further comprises a plurality of fittings; wherein the housing comprises a plurality of snap-fit connections spaced along an interior surface thereof for securing the plurality of fittings; wherein each of the plurality of fittings is coupled to a nozzle having an orifice formed therein for spraying the pressurized liquid outwardly from the manifold assembly.

7 . A misting fan system comprising:
a fan including a motor and a plurality of fan blades operably coupled thereto, each of the fan blades comprising a base member and a paddle member mated to the base member, each paddle member comprising a leading edge and a trailing edge relative to a direction of movement of the paddle member when the fan is in operatic wherein the leading edge is thinner than the trailing edge; and a mister positioned above the fan.

8 . The misting fan system of claim 7 , further comprising a support shaft connected to the fan for supporting the fan above a ground surface, wherein the mister is coupled to the support shaft.

9 . The misting fan system of claim 7 , further comprising a fan motor housing connected to the fan, wherein the mister is coupled to the fan motor housing.

10 . The misting fan system of claim 7 , wherein the leading edge is higher than the trailing edge.

11 . The misting fan system of claim 7 , wherein the mister comprises:
a housing that is substantially circular; and a manifold assembly disposed within the housing, the manifold assembly comprising an inlet for a pressurized liquid, wherein the inlet is in fluid communication with a fluid source.

12 . The misting fan system of claim 11 , mister further comprises a plurality of nozzles disposed within the housing and radially spaced apart from each other, wherein each of the plurality of nozzles is in fluid communication with the manifold assembly and includes an orifice for spraying the pressurized liquid outwardly from the manifold assembly, wherein the housing further includes a plurality of holes formed in an outer wall thereof for allowing the pressurized liquid to spray outwardly from the housing, and wherein each of the plurality of nozzles is at least partially disposed within the outer wall of the housing.

13 . The misting fan system of claim 12 , wherein the manifold assembly further comprises a plurality of fittings, wherein the housing comprises a plurality of snap-fit connections spaced along an interior surface thereof for securing the plurality of fittings, and wherein each of the plurality of fittings is coupled to a nozzle having an orifice formed therein for spraying the pressurized liquid outwardly from the manifold assembly.

14 . A misting fan system comprising:
a fan including a motor and a plurality of fan blades operably coupled thereto, the fan blades each comprising a base member and a paddle member mated to the base member, each paddle member comprising an inner end proximate the motor and an outer end distal to the motor, wherein the inner end is spaced a first distance away from a central axis; a fan motor housing connected to the fan; a support shaft connected to the fan for supporting the fan above a ground surface; and a mister positioned above the fan, the mister comprising a substantially circular housing having an inner radius and an outer radius, wherein the outer radius is greater than the first distance, and wherein the mister is coupled to at least one of the fan motor housing or the support shaft.

15 . The misting fan system of claim 14 , wherein the housing is made of a heat and humidity resistant thermoplastic.

16 . The misting fan system of claim 14 , wherein the mister further comprises a manifold assembly disposed within the housing, the manifold assembly comprising an inlet for a pressurized liquid, wherein the inlet is in fluid communication with a fluid source.

17 . The misting fan system of claim 16 , wherein the inlet is in fluid communication with a pump.

18 . The misting fan system of claim 14 , wherein the mister further comprises a plurality of nozzles disposed within the housing and radially spaced apart from each other, wherein each of the plurality of nozzles is in fluid communication with the manifold assembly and includes an orifice for spraying the pressurized liquid outwardly from the manifold assembly, and wherein the housing further includes a plurality of holes formed in an outer wall thereof for allowing the pressurized liquid to spray outwardly from the housing;
wherein each of the plurality of nozzles is at least partially disposed within the outer wall of the housing.

19 . The misting fan system of claim 18 , wherein each of the plurality of nozzles is disposed completely within the outer wall of the housing.

20 . The misting fan system of claim 18 , wherein the manifold assembly further comprises a plurality of fittings, wherein the housing comprises a plurality of snap-fit connections spaced along an interior surface thereof for securing the plurality of fittings, and wherein each of the plurality of fittings is coupled to a nozzle having an orifice formed therein for spraying the pressurized liquid outwardly from the manifold assembly.
