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.

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 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.

Diagram of Positive Air Pressure

Positive Air Pressure

  1. Pushes hot and/or humid air into walls and insulation; condensation can lead to mold, mildew and rot
  2. Heat loss
Diagram of Negative Air Pressure

Negative Air Pressure

  1. Cold air infiltrates house
  2. May increase energy costs
  3. May cause combustion appliances to backdraft
Diagram of Equal Air Pressure

Equal Air Pressure

  1. Supply airflow is equal (CFM) to stale air exhaust
  2. Balancing is required on all units unless specified otherwise.

Air Oasis HVAC Induct Air Purifier imageGet the Ultimate in Clean Air for Your Home

Combine an Air Oasis Induct Air Purifier with a Venmar Ventilation System (or any HVAC system) and get the ultimate in pure air in your home.

The Venmar Air Exchange System is fabulous for recovering heat or energy, providing fresh air, controlling humidity and removing particulate (dust, pollen, dander, etc.), but by adding the powerful broad-spectrum pollution purification abilities of an Air Oasis HVAC Induct Air Purifier, you get the ultimate in whole-house clean air. Air Oasis air purifiers destroy bacteria, viruses, pesticides, herbicides, mold spores, chemical fumes and gases, VOCs, odors and more from your ductwork and every room served by a vent.

The ONLY Induct Air Purifier with Rotational UV Shield Technology

Since UV lamps were first used in HVAC systems there has been one constant complaint from HVAC engineers and contractors. UV light can degrade many of the rubbers and plastics used within an HVAC system causing premature system failure. Air Oasis has created the perfect solution. With the development of their proprietary Rotational UV Shield you can control how little or how much UV light is emitted from the unit, while allowing for a constant stream of air to pass through the AHPCO Cell for treatment. The Rotational UV Shield can be rotated 360 degrees exposing more or less of the UVC lamp. (Click here to read why most induct UV lamps are not as effective as claimed).

The residential and business HVAC (heating, ventilation and air conditioning) induct models are designed for use with forced-air heating and central air conditioning systems (HVAC) to purify the air in all rooms served by ductwork in small to large single-family homes and office buildings. Turn your central heating and cooling system into an air-cleaning machine to significantly reduce pollutants and contaminants in your entire home or business. For more information, see the Air Oasis Air Purifiers.
