For new or retrofit installations, the Amana® brand AVPTC Air Handler supplies consistent airflow over a range of static pressure conditions, regardless of the duct system. Up to 12 field-selectable airflow settings optimize CFM. The Amana Air Handler's variable speed motor enables more even distribution of the air from room-to-room and floor-to-ceiling, reducing the likelihood of hot and cold spots in the house compared to single-speed unit.

The Lennox T-Class™ line of split systems features compact indoor units no more than 30-in. wide, to fit through standard 32-in. doorways and comes fully assembled.

According to company sources, a good match for the T-Class 6- to 20-ton air conditioners and heat pumps is the TAA air handler. Factory-provided thermostatic expansion valves and easy refrigerant line access help reduce installation time, while multiple circuit coils offer 50/50 face split two-stage capacity operation for increased comfort (available with 7.5- to 20-ton models).

McQuay's fan array for Vision™ indoor air handlers offers multiple fan combinations for increased flexibility. By incorporating an array of smaller fans in place of one large fan, McQuay’s fan array reduces footprint size, noise and maintenance, while providing redundancy and design air-flow for critical installations. Ideal for replacement projects, the fan array section can be disassembled into smaller components for easier service.

Available in 7.5-, 10-, 15- and 20-ton sizes, the smartly designed Rheem RHGL Series of commercial air handlers provides businesses with the utmost in reliability and performance. Contractors, in turn, benefit from several features that make the unit easy to install and service. The low-profile nature of the unit allows for both vertical and horizontal installations, thereby giving contractors greater flexibility to adapt to a variety of installation scenarios.

Also available is the Rheem hydronic air handler, which is an integral piece of the Rheem integrated heating and water heating system, which is a unique system that heats both the air and water in a home. When a Rheem tankless gas water heater is matched with the Rheem hydronic air handler, hot water is circulated through the air handler to produce heat and is then re-circulated back to the tankless water heater to ensure that no water is wasted. According to company sources, this pairing of products provides a soft, comfortable heat to the home while maintaining comfortable humidity levels regardless of the climate.
