Air terminal units are small air handlers designed for local use and may only include an air filter, coil, and blower. These simple terminal units are called “blower coils” or “fan-coil units.” Makeup air units are larger air terminals that condition 100 % outside air (and no recirculated air). Air handlers designed for outdoor use, typically mounted on rooftops, are known as packaged units (PU) or rooftop units (RTU).

Dampers are designed to prevent fire and smoke from spreading from a fire source through the ventilation system and into other parts of the building. Depending on their application, fire dampers have different fire-resistance classes (called “fire-duration ratings”) and can be installed in concrete or masonry walls and in lightweight partition walls.

Available in hundreds of configurations and sizes, drains can be used to remove water, chemicals, oil and other liquids from buildings, parking structures and roadways. Some units are designed to collect and separate particles, oils and grease from liquid or to keep contaminants from entering the water supply. Many materials are available including cast iron, PVC, stainless steel and bronze. Manufacturers: Jay R Smith

An air handling unit (AHU), conditions and circulates air as part of a heating, ventilating, and air-conditioning (HVAC) system. A typical air handler is a large metal box containing a blower, heating andor cooling element, filter racks or chambers, sound attenuators, and dampers. Air handlers connect to ductwork that distributes the conditioned air throughout the building and returns it to the AHU. AHUs can alternately be set up to discharge (supply) and admit (return) air directly to and from the space served without ductwork.

Cartridge filters are used to filter Chlorine from water eliminating bad taste and odor. There are several different types of filter designs including depth and pleated. Media types include carbon, coconut carbon, ceramic and membrane. Manufacturers: Watts Water Treatment

Mounted inline in an HVAC system Electric Duct Heaters heat air as it passes over an electrically heated coil. The units can be actuated remotely by connecting them to the Building Management System or locally via temperature sensor.Mounted inline in an HVAC system Electric Duct Heaters heat air as it passes over an electrically heated coil.
