PERFECT WINDOW™ FRESH AIR VENTILATION SYSTEMS Features...

• Provides ventilation that helps contractors meet ASHRAE 62-89 • Reduces air conditioning loads • Energy transfer wheel for heat recovery • Rugged steel cabinet

• No drain required, condensation free

• Exhasts up tp 200 CFM of stale air while bringing in equal amounts of fresh air

• Permanently lubricated fan and wheel bearings • Permanent washable prefilter • Minimal operational costs @ 115 Volts

The Honeywell energy & heat recovery ventilators allow constantly replenished fresh outdoor air to be circulated throughout the home without the waste of heating or cooling. Unlike most conventional fresh air ventilators, which waste 100% of heating or cooling energy, these ventilators recover up to 85% of the energy already spent to heat or cool the circulating air. The heart of the Perfect Window™ is a heat transfer core that transfers heating or cooling energy from outgoing to incoming airstreams. The ER Model has a patented desiccant coated wheel which reduces humidity in the summer and retains humidity in the winter. It is so effective that it will reduce the load on an air conditioner and may eliminate the need for a humidifier. Features include, heat transfer core, pre-filters, fan and blower assembly and defrost. Easy to clean cross-flow core assures years of trouble-free operation.

“VOCS”

The term “VOCs is showing up more and more in current HVAC conversations and literature. What exactly are VOC’s? “VOCs” is an abbreviation for “Volatile Organic Compounds”. VOCs are chemical compounds which evaporate and disperse easily at room temperatures. The chemical compounds can contaminate indoor air to a point that they become harmful to humans over extended exposure periods. Typical effects of high levels of VOCs are eye irritation, nose irritation, throat irritation, headaches, nausea/vomiting, dizziness, and asthma exacerbation.

Where do VOCs come from? They are all around us in forms we recognize, but do not recognize the potential danger. They off- gas from paints, moth balls, solvents, vinyl flooring, carpets, adhesives, upholstery, cosmetics, pressed wood products, air freshen- ers, fabric softners, common household cleaners, etc. High levels of any single, or combination, of Vocs can cause reactions and lead to long term illness. What chemicals are contained in the above mentioned sources? Many different chemicals are contained in the various sources. Most prevalent, would be benzene, methylene, chlorides, formaldehyde., ethylene, and butadiene.

What can be done to correct high levels of VOCs? Concentrations depend on the volume of the air, the VOC off-gas rate, and the building ventilation rate. A couple of methods of control should be used. First, identify and when possible, remove the source. (IE: Seal paint cans, use environmentally approved cleaners which do not contain VOCs, select products which do not off-gas car- bon VOCs.) Another method to lower VOC concentration is to increase the volume of air by increasing the indoor ventilation rate. Yes, you could open a window, or you could use a fresh air ventilation system. Use of fresh air ventilation systems is the preferred method to provide air changes and conserve energy usage when the HVAC equipment is in operation.

The R.E.Michel Company carries Honeywell, and Aprilaire, “fresh air ventilation systems” to meet this need. (See Honeywell Cat numbers 2C864 thru 2C8867, and 2C889. Aprilaire Cat numbers 8L032 and 8L8126)
