a grille configured to be coupled to the main housing and defining at least one aperture; and
a plate coupled to the grille and defining an intake gap with a portion of the grille, the intake gap defining an airflow path into the main housing;
wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall including mounting notches.
2. The ventilation system of claim 1 wherein the plate defines a generally annular shape.
3. The ventilation system of claim 1 wherein the plate is larger than the grille.
4. The ventilation system of claim 1 wherein the plate is larger than the grille such that it extends laterally beyond the at least one grille aperture.
5. The ventilation system of claim 1 wherein the plate is smaller than the grille.
6. The ventilation system of claim 1 wherein the surface of the plate is at least partially textured.
7. The ventilation system of claim 1 wherein the plate comprises multiple plate units.
8. The ventilation system of claim 1 wherein the plate defines a plate aperture located substantially centrally on the plate.
9. The ventilation system of claim 1 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall having a generally textured surface.
10. The ventilation system of claim 1 wherein the grill defines a substantially curved area which engages the plate.
11. The ventilation system of claim 1 wherein air first passes through the intake gap before passing through the at least one grille aperture.
12. A ventilating system comprising:
a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing;
a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet;
a grille configured to be coupled to the main housing and defining at least one aperture; and
a plate coupled to the grille and defining an intake gap with a portion of the grille, the intake gap defining an airflow path into the main housing;
wherein the grill defines a substantially curved area which engages the plate.
13. A ventilating system comprising:
a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing;
a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet;
a grille configured to be coupled to the main housing and defining at least one aperture; and
a plate coupled to the grille and defining an intake gap with a portion of the grille, the intake gap defining an airflow path into the main housing;
wherein air first passes through the intake gap before passing through the at least one grille aperture.
14. A ventilating system configured for ventilating a space comprising:
a main housing defining an inlet configured to receive air from the space into the main housing and an outlet configured to allow the air exit the main housing;
a fan supported in the main housing and configured and arranged to generate a flow of air from the space into the main housing through the inlet and from the main housing through the outlet;
a grille configured to be coupled to the main housing, the grille defining at least one aperture and a lamp aperture;
a plate engaged with the grille and defining an intake gap with a portion of the grille, the intake gap defining an airflow path into the main housing; and
a lamp housing coupled to the grille substantially adjacent the lamp aperture, and the lamp housing including a first set of illumination devices;
wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall including mounting notches.
15. The ventilation system of claim 14 wherein the plate defines a generally annular shape.
16. The ventilation system of claim 14 wherein the plate is larger than the grille.
17. The ventilation system of claim 14 wherein the plate is larger than the grille such that it extends laterally beyond the at least one grille aperture.
18. The ventilation system of claim 14 wherein the plate is smaller than the grille.
19. The ventilation system of claim 14 wherein the surface of the plate is at least partially textured.
20. The ventilation system of claim 14 wherein the plate comprises multiple plate units.
21. The ventilation system of claim 14 wherein the plate defines a plate aperture located substantially centrally on the plate.
22. The ventilation system of claim 14 wherein the plate defines a plate aperture located substantially centrally on the plate formed by a plate aperture wall and the plate aperture wall having a generally textured surface.
23. The ventilation system of claim 14 wherein the grill defines a substantially curved area which engages the plate.
24. A ventilating system configured for ventilating a space comprising:
a main housing defining an inlet configured to receive air from the space into the main housing and an outlet configured to allow the air exit the main housing;
