Air Cleaners 24 Volt Central System Electronic Air Cleaner Connects with 24 volt wires from the existing transformer on the heating and/or air conditioning unit to the air cleaner directly. Cheaper, faster and easier to install. Eliminates the need for a sail switch or pressure switch with a built-in solid state airflow sensing device. Uses 40VA transformer already on the furnace and/or air conditioner. Power supply boosts the 24-volt input to proper high voltage to the collector cells. Maintains consistent output voltage to the cells for maximum efficiency. No other air cleaner does this. With other cleaners, the voltage to the cells drops as they collect and efficiency decreases. Adams Cleanaire Central System Return Grill Electronic Air Cleaner For homes, condominiums, apartments, mobile homes and applications where there is a common return grill rather than separate return air ducts from each room, the RG-1000 fits the bill. Larger homes with more than one return grill may require an additional return grill air cleaner, but will find that this improves the air quality even more. Self-Contained Ceiling Mount Electronic Air Cleaner Maintains constant output voltage to the cell for maximum efficiency. With other cleaners, the voltage to the cells drops as it collects and efficiency decreases dramatically.
