Abstract
A ventilator includes a ventilator housing defining an exhaust air flow section and a fresh air flow section, a rotary wheel, a heat and moisture exchange media supported by the rotary wheel and intersecting the exhaust air flow section and the fresh air flow section, a rotary wheel mounting assembly including a first set of guide rollers in contact with a first rim edge portion of the rotary wheel and a second set of guide rollers in contact with a second rim edge portion of the rotary wheel, and a drive roller in contact with one of the rim edge portions. A hub and bearing assembly is provided such that the rotary wheel may tilt with respect to the mounting assembly. A rotary wheel access plate defines an exhaust air outlet and a fresh air inlet and is equipped with an access plate opening assembly. A moisture transfer wick extends across a partition assembly between the exhaust air flow section and the fresh air flow section. A rotary wheel seal positioned between the circumferential rim of the rotary wheel and the ventilator housing includes first and second sealing members pivotally mounted on one end thereof and spring mounted on another end thereof. The rotary wheel, which is designed to enable maintenance of wheel circularity, is mounted so as to be readily removable from the ventilator housing. Similarly, in one embodiment of the present invention, the exchange media is arranged so as to be readily removable from the rotary wheel.
