1. A blower system comprising:
- a housing having a housing chamber, at least one inlet opening, a primary outlet opening, and a secondary outlet opening; and
a fan assembly mounted within the housing chamber, wherein;
operation of the fan assembly draws air into the housing chamber through the at least one inlet opening and forces air out of the housing chamber through at least one of the primary outlet opening and the secondary outlet opening, and further wherein a cross-sectional area of the secondary outlet opening is between approximately one percent and ten percent of a cross-sectional area of the primary outlet opening.

Abstract
A blower system comprising a housing and a fan assembly. The housing defines a housing chamber, at least one inlet opening, a primary outlet opening, and a secondary outlet opening. The fan assembly is mounted within the housing chamber. Operation of the fan assembly draws air into the housing chamber through the at least one inlet opening and forces air out of the housing chamber through at least one of the primary outlet opening and the secondary outlet opening.

10. A blower system comprising:
-
a housing having a housing chamber, at least one inlet opening, a primary outlet opening, and a secondary outlet opening; a fan assembly mounted within the housing chamber; first, second, and third pairs of foot members, wherein the first and second pairs of foot members define a first reference plane, and the second and third pairs of foot members define a second reference plane, wherein the second reference plane is angled with respect to the first reference plane; wherein operation of the fan assembly draws air into the housing chamber through the at least one inlet opening and forces air out of the housing chamber through at least one of the primary outlet opening and the secondary outlet opening; and wherein air flowing out of the primary outlet opening flows along a primary flow axis that is generally parallel to the first reference plane. - View Dependent Claims (11)

12. A method of causing air to flow along a target surface, comprising the steps of:
-
positioning a housing proximate to the target surface, the housing having a housing chamber, at least one inlet opening, a primary outlet opening, and a secondary outlet opening, the housing carrying a fan assembly and first, second, and third pairs of foot members, wherein the first and second pairs of foot members define a first reference plane, the second and third pairs of foot members define a second reference plane, and the second reference plane is angled with respect to the first reference plane; arranging the housing in a first orientation with respect to the target surface such that the first and second sets of foot members engage the target surface; arranging the housing in a second orientation with respect to the target surface such that the second and third sets of foot members engage the target surface; and operating the fan assembly such that air is drawn into the housing chamber through the at least one inlet opening and forced air out of the housing chamber through the primary outlet opening and the secondary outlet opening. - View Dependent Claims (13, 14, 15, 16)

17. A blower system comprising:
-
a housing having a housing chamber, at least one inlet opening, a primary outlet opening, and a secondary outlet opening; and a fan assembly mounted within the housing chamber; first and second pairs of foot members that define a reference plane;
wherein;the primary opening defines a primary flow axis and the secondary outlet opening defines a secondary flow axis, where the secondary flow axis is angled with respect to the primary flow axis; operation of the fan assembly draws air into the housing chamber through the at least one inlet opening and forces air out of the housing chamber through the primary outlet opening and the secondary outlet opening, wherein air flowing out of the primary outlet opening flows along a primary flow axis that is generally parallel to the reference plane. - View Dependent Claims (18)
