Camfil-Farr released the MERV 8 30/30 air filter. The MERV 8 filter holds 30 percent more dust than conventional filters, which means longer service life and fewer change-outs, according to the company. The filter media is mechanical instead of electrostatic so it does not lose power as it collects dust, according to the company.Read more
ICM Controls introduces the CC750 Comfort Control Center, a variable frequency/voltage blower motor speed control that helps maintain air quality and moisture levels. It controls the blower speed in existing HVAC systems and reduces humidity levels by removing excess moisture in the air.
The product can be used with a system equipped with advanced indoor air quality devices and installed by a trained HVAC contractor. It uses a menu-driven program and is designed for single-phase systems. It is available in 115 VAC and 230 VAC models.Read more
DuctSox introduces the Designer Series fabric option for HVAC systems, a patterned fabric duct collection for commercial buildings with exposed ductwork. The series features a UL-approved polyester-blend fabric with a built-in antimicrobial treatment to minimize mold and mildew.
The set can be hung with a suspension cable, H-track or a suspension system that displays perpetual duct inflation during idle air handling periods.Read more

Pumps are available in 2 to 6 tons with efficiencies up to 31.5 EER and 5.1 COP. They are rated for water loop heat pump, ground loop heat pump and ground water heat pump in upflow, downflow, horizontal and split system configurations.Read more
Zimek manufactures a room-sterilizing system that enables the complete sterilization of all interior air within a confined space and disinfects all surfaces wherever free air flows, according to the company. Inside each system is a micro-particle generator that converts a disinfectant solution into negatively charged ion particulates. The particulates attach to positively charged contaminants in a room and attack all surfaces.Read more
Lennox’s Humiditrol dehumidification system removes moisture based on relative humidity levels instead of a thermostat, while maintaining ASHRAE 62.1 2004 fresh air requirements. Available on many Lennox L series rooftop units, the Humiditrol system uses a patented hotgas reheat design to control humidity, removing more than 1.44 gallons of water per hour at 65 degrees Fahrenheit. When humidity levels are high, the system delivers a dehumidified and neutral air supply. The system adds only three components to standard cooling systems.Read more
