Air Exchange Systems
How Venmar Home Ventilation
Systems Work
Air Exchange Concept
Venmar air exchangers employ
advanced technology to efficiently expel excess humidity, reduce gaseous
pollutants and bring a continuous supply of fresh outdoor air into the home.
Only an air exchanger can perform this task.

appropriate operation of Venmar Air Exchange units inside the house:
 
The Impact of Negative or Positive Indoor Air
Pressure
It is important not to neglect the impact of an unbalanced
ventilation system. If an air exchanger unit does not expel and intake equal
amounts of air, a negative or positive air pressure imbalance occurs.
Venmar air exchangers sold in retail home improvement center
are factory balanced. This means when installing these units following the
installation instructions, there is no need to balance them. All other
units must be balanced by an HVAC (Heating, Ventilating and Air
Conditioning) professional.
Positive
Air Pressure
- Pushes hot and/or humid air into walls and insulation; condensation
can lead to mold, mildew and rot
- Heat loss
Negative
Air Pressure
- Cold air infiltrates house
- May increase energy costs
- May cause combustion appliances to backdraft
Equal
Air Pressure
- Supply airflow is equal (CFM) to stale air exhaust
- Balancing is required on all units unless specified otherwise.
