A ventilation exhaust fan is provided, and in some embodiments includes a housing adapted to interchangeably receive a first module having a first support plate and a second module having a second support plate. Each of the first and second modules have at least one of a motor and a fan wheel operable to generate a flow of fluid into and out of the exhaust fan. At least one of the motor and fan wheel of the first module is different from the motor and the fan wheel of the second module, respectively.

What is claimed is: 1. A ventilation exhaust fan comprising: a housing having a fluid inlet opening through which fluid is received within the housing and a fluid outlet through which fluid exits the housing, the housing adapted to interchangeably receive, through the fluid inlet opening, a first module having a first support plate; and a second module having a second support plate, each of the first and second modules having a motor and a fan wheel operable to generate a flow of fluid out of the fluid outlet; wherein at least one of the fan wheel and the motor of the first module has a performance characteristic different than at least one of the fan wheel and the motor of the second module, respectively. 2. The ventilation exhaust fan of claim 1, wherein the at least one of the fan wheel and the motor of the first module has a different size than the at least one of the fan wheel and the motor of the second module. 3. The ventilation exhaust fan of claim 2, wherein the size is an axial length of each fan wheel. 4. The ventilation exhaust fan of claim 1, wherein the at least one of the fan wheel and the motor of the first module generates a noise different than the at least one of the fan wheel and the motor of the second module, respectively. 5. The ventilation exhaust fan of claim 1, wherein the at least one of the fan wheel and the motor of the first module has a substantially similar size to the at least one of the fan wheel and the motor of the second module, respectively. 6. The ventilation exhaust fan of claim 5, wherein the size is a measure of output power of each motor. 7. The ventilation exhaust fan of claim 1, wherein the at least one of the fan wheel and the motor of the first module has a different efficiency than the at least one of the fan wheel and the motor of the second module, respectively. 8. A ventilation exhaust fan comprising: a housing having a fluid inlet opening through which fluid is received within the housing and a fluid outlet through which fluid exits the housing, the housing adapted to interchangeably receive, through the fluid inlet opening, a first module having a first support plate; and a second module having a second support plate, each of the first and second modules having a motor and a fan wheel operable to generate a flow of fluid out of the fluid outlet; wherein the motor of the first module one of generates a noise different than and has a performance characteristic different than the motor of the second module. 9. The ventilation exhaust fan of claim 8, wherein the fan wheel of the first module has a performance characteristic different than the fan wheel of the second module. 10. The ventilation exhaust fan of claim 8, wherein at least one of the fan wheel and the motor of the first module has a different size than at least one of the fan wheel and the motor of the second module. 11. The ventilation exhaust fan of claim 10, wherein the size is an axial length of each fan wheel. 12. The ventilation exhaust fan of claim 8, wherein at least one of the fan wheel and the motor of the first module has a substantially similar size to at least one of the fan wheel and the motor of the second module, respectively. 13. The ventilation exhaust fan of claim 12, wherein the size is a measure of output power of each motor. 14. The ventilation exhaust fan of claim 8, wherein at least one of the fan wheel and the motor of the first module has a different efficiency than at least one of the fan wheel and the motor of the second module, respectively. 15. A ventilation exhaust fan comprising: a housing having a fluid inlet through which fluid is received within the housing and a fluid outlet through which fluid exits the housing, the housing adapted to interchangeably receive a first module having a first support plate; and a second module having a second support plate such that one of the first support plate and the second support plate extends across the fluid inlet, each of the first and second modules having a motor and a fan wheel operable to generate a flow of fluid out of the fluid outlet; wherein at least one of the fan wheel and the motor of the first module has a different efficiency than at least one of the fan wheel and the motor of the second module, respectively. 16. The ventilation exhaust fan of claim 15, wherein the at least one of the fan wheel and the motor of the first module has a different size than the at least one of the fan wheel and the motor of the second module. 17. The ventilation exhaust fan of claim 16, wherein the size is an axial length of each fan wheel. 18. The ventilation exhaust fan of claim 15, wherein the at least one of the fan wheel and the motor of the first module generates a noise different than the at least one of the fan wheel and the motor of the second module, respectively. 19. The ventilation exhaust fan of claim 15, wherein the at least one of the fan wheel and the motor of the first module has a substantially similar size to the at least one of the fan wheel and the motor of the second module, respectively. 20. The ventilation exhaust fan of claim 19, wherein the size is a measure of output power of each motor. 21. The ventilation exhaust fan of claim 15, wherein the at least one of the fan wheel and the motor of the first module has a performance characteristic different than the at least one of the fan wheel and the motor of the second module, respectively.
