Little boy using an inhaler due to poor air qualityVenmar heat recovery ventilators breathe new life into your home or building and help reduce the risk of polluted air. Based on the principle of bad air in, good air out, these units revitalize your whole home, not just selected areas.

Mounting evidence has shown that dependence on the natural exchange of air between indoor and outdoor through air infiltration and exfiltration may not be satisfactory for good moisture control and indoor air quality. Plus traditional ventilation methods, like opening a window or use of a common fan, do not provide adequate ventilation. An Energy Recovery Ventilation system is the key to positive moisture control and heat recovery and will help ensure a healthy indoor environment for the occupants.

Mechanical ventilation systems are used to bring fresh air into and remove stale air from our homes. Two common types are exhaust-only systems and balanced systems. The exhaust-only system has a fan to provide exhaust air; the supply air is not fan powered. The balanced system uses a fan-powered exhaust airflow that is designed to equal the fan-powered supply airflow. The balanced systems may or may not have heat or energy recovery. Those with heat or energy recovery are commonly called Heat Recovery Ventilation (HRV) or Energy Recovery Ventilation (ERV). An HRV transfers heat while an ERV usually transfers heat and moisture.

Venmar air flow diagram from fresh air in to stale out outA Heat Recovery Ventilation system uses fans to maintain a low-velocity flow of fresh outdoor air into the building (incoming air stream) while exhausting out an equal amount of stale indoor air (exhaust air stream). Fresh air is supplied to all levels of the building while stale air is removed from areas with high levels of pollutants and moisture.

In colder climates, where home heating is essential, the Venmar Heat Recovery Ventilator (HRV) is the proper choice. The HRV keeps the home supplied with a steady flow of fresh outdoor air. As stale, warm air is expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout the home. The result is a constant supply of fresh air, no unpleasant drafts and greater home comfort. In addition to heat recovery and improved air quality, the HRV provides necessary ventilation while controlling excess humidity.

How Venmar Home Ventilation Systems Work

Image of air exchange

Air Exchange

Expels stale, polluted indoor air and gaseous pollutants and continually exchanges them with a continuous flow of fresh, revitalized outdoor air to improve Indoor Air Quality.

images of high humidityExcess Humidity Control

Helps prevent uncontrolled excess humidity by expelling excess humidity from the air, thereby reducing the risk of window condensation, mildew and mold, which prevents structural damage and deterioration to your home.

Heat Recovery Core

Certain Venmar Air Exchangers feature a heat recovery system. As warm air is expelled from your house, it warms the incoming cold, fresh air before its circulated throughout your home. The result is a constant supply of fresh air, no unpleasant drafts and greater home comfort.

The best way to achieve optimal air quality in your home is to combine HEPA filtration with Air Exchange. Together, they create the ultimate system for people who want a clean and healthy environment. HEPA filters capture 99.97% of all dust and particles as small as 0.3 microns (1 human hair = 150 microns). They can help reduce allergy symptoms, asthma, recurring colds and persistent coughs. In fact, HEPA filters are so effective, theyre used in hospital operating rooms.

I purchased a HEPA 3000 air exchange unit from Venmar last fall. I want to let you know how much it has improved our familys quality of life. This system has solved the humidity problem we had in our home, and it has decreased the amount of dust suspended in the air thanks to its HEPA filter. The children felt better as early as last winter. Less coughing and fewer bouts of asthma! I can recommend your system to my friends for their families well-being without any hesitation whatsoever."

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.
