AIR DISTRIBUTION: Out With the Old, In With the New

Sept. 1, 2009
New and innovative products are available to help improve the air we breath.


With the ability to reduce bacteria, viruses and mold — plus chemical and biological odors — Amana® brand UVX Ultraviolet Object Purifiers are used in any location where clean air is desired.

A patent-pending, aluminum parabolic reflector directs and intensifies all UV energy to the desired area, ensuring a coil free of microbial growth. Units use a high-intensity, 19mm quartz, germicidal UVC lamp (UVX-PR Series). The Amana UVX-PR also features the ultra-bright LED “Smart Lamp System” visual display and a 3-year limited warranty.

Carrier's line of ventilators include HRV (heat recovery ventilator) and ERV (energy recovery ventilator) models. Carrier ventilators exhaust stale air from the building and replace it with fresh air from outside, and transfer heat between the air streams with up to 84% efficiency.

Unlike rotary wheel heat exchangers which mix air streams, Carrier ventilators use cross-flow or counterblow heat exchange cores to ensure there is no mixing of the incoming and exhaust air. HRVs are normally selected for cooler climates. ERVs have the ability to transfer moisture through the core material and are usually applied in climates that experience high temperatures and humidity levels.

Comfort-Aire introduces its AHGV series of variable speed hydronic air handlers for R-410A. According to company sources, the variable speed blower motor operates 90% more efficiently than PSC motors. It further improves efficiency by adjusting the CFM to match the static pressure of the system, helping to overcome poor duct design and long duct runs. This improved air distribution throughout the static pressure range results in a constant low speed fan operation.

The AHGV series has features including freeze protection in both heating and cooling, slide-out blower assembly, line voltage terminal block and low voltage terminal strip, and ¾-in. sweat water connections.

Field Controls

Field Controls introduces the Media Air Cleaner product line. Initially available in two sizes, both use MERV 11 rated filter media to trap particles as small as 1.0 micron in size. Replacement filters are designed to fit standard Media Air Cleaner cabinets. The 1400 cfm size is 16-in. × 25-in. × 5-in. The 2000 cfm model is 20-in. × 25-in. × 5-in.

Field Controls media is electrostatically supercharged for better efficiency and longer life. It's also moisture resistant, and will not support the growth of bacteria or microbes. The MERV 11 pleated media has enough capacity to work up to six months before replacement while maintaining efficiency and arrestance ratings in compliance with ASHRAE Standard 52.2.

PreVent® equipment protection filters provide the first line of defense in preventing debris from entering the HVACR system and insulating coils, electronics and other sensitive components. Airborne debris, such as cottonwood, can clog air intakes, reducing air flow by as much as 50% or more, and ultimately cause system failure. A proactive approach to equipment maintenance helps deliver consistent high level performance and minimize downtime. PreVent filters are made of permanent, washable black polypropylene with UV protection. Custom made to exact air intake dimensions with a flexible vinyl or rigid steel frame, the PreVent filter can be easily mounted on an equipment housing using a variety of unique attachments available.

The EAMS060 by Ruskin combines electronic air measuring with an ultra low leak, airfoil blade, control damper and actuator. The building automation system (BAS) sends a setpoint cfm to the controller and the factory commissioned actuator modulates to control to that setpoint. The output signal confirms the flow to the BAS. This damper saves energy with AMCA Class 1 leakage and meets the requirements of the IECC. Electronic controls are temperature and altitude compensating. A flow control potentiometer facilitates field calibration so the controller can be fine-tuned to an accuracy of 1% of set point.

Tamarack Technologies

Tamarack Technologies introduces the Multi-Aire IIP and IIN balanced ventilation system. This ventilation system introduces fresh, filtered air into the home, balances air pressure, and pulls stale air out of the house.

Called “Multi-Aire II,” the system relies on two mechanical devices, one of which pulls in healthy, refreshing air while the other exhausts polluted air. It offers both negative and positive air exchange, thus creating balanced airflow even in what is often referred to as an “airtight” home.
