AireShare Level to Level Ventilator

The AireShare™ Level to Level Ventilators distribute air from one conditioned space to another. Virtually every home has temperature differentials on different levels of the house. The AireShare™ moves air from one level of the house to a room on another level of the house that is uncomfortably hot or cold. This air movement helps to de-stratify stagnant air in homes, improve ventilation rates and make both rooms more comfortable.

AireShare™ Level-to-Level transfer fans are perfect for hard to heat or cool levels. Ultra quiet, flush mount design efficiently moves air through interior floors to uncomfortable levels. De-stratify stagnant air and improve ventilation rates inside home for greater comfort. Move air from levels that are not directly served by ductless heating/cooling, split system, PTAC & window A/C units. Also great for electric baseboard, stoves & fireplaces.

Quick Comfort Calculation

Multiply the Length x Width x Height of the uncomfortable room (in feet) and then divide by 75 to determine the number of minutes needed to bring the uncomfortable room to nearly the same air temperature as the adjacent room.

Example: 15 ft x 15 ft x 8 ft - 1800 Cubic Ft ÷ 75 = 24 minutes

Calculation relates to air temperature and makes certain basic assumptions.  It is recommended that the AireShare be operated for an extended period so that objects within the room such as walls and furnishings also equal the air temperature.

Question: Is this unit able to reverse direction? upper to lower and then lower to upper?
Answer: No, the fan motor is not reversible. You can use two Level to Level Ventilators and use one in each direction.
