          2.4SMART ECM CLEANROOM FAN FILTER UNITS
 
          A.General Characteristics:
          1.Low-energy, electrically-commutated (EC) fan/filter units comply with energy-efficiency standards including California's Title 24 and the European Union's ErP 2015 Directive. Brushless DC motors have internal micro-processors, and lower decibel levels than mechanical AC motors. At medium setting, the sound level are 40 dBA.
          2.Units use a smart control system, that consume only 280W/2.4A @109 FPM (0.55 m/s) and greatly reducing cleanroom operating costs. Smart ECM units can help earn LEED points, further reducing operating cost. ECM units generate less heat than AC FFUs, and provide a much wider flow range, from 110 to 1117 CFM, and are ideal for applications involving high static pressure.
          3.Smart ECM low-energy DC units can be incorporated into Building Management Systems to allow remote monitoring and control. Units can also be adjusted via IR transmitters from inside the room, or via a remote touchscreen PLC console.

          2.6VAPOR REMOVAL AND SANITIZING MODULES
 
          A.Vapor Removal and Sanitizing Module; 2 foot by 4 foot, adapter adds capabilities to the WhisperFlow Fan/Filter Units including Carbon Prefilter that removes volatile organic compounds (VOCs) to ensure a safe, clean process environment and a prefilter that also helps compensate for VOC spikes that might occur during certain operations.
          1.Photo-Catalytic Oxidation Panel (PCO) removes volatile organic compounds (VOCs) remaining in the air stream after they pass the carbon filter. The PCO panel is highly efficient at vapor removal, yet imposes no restriction on air speed, allowing the Fan/Filter Module to maintain air speeds consistent with ISO cleanliness requirements (typically 80-100 feet/minute).
          2.UV Sanitizer kills most bacteria, viruses and molds to eliminate biological hazards inside the cleanroom. It also energizes the PCO, boosting its vapor-adsorption efficiency.
          3.Requires an adapter module for each 2 foot by 4 foot (610 mm by 1219 mm) FFU. Includes adapter housing, one charcoal pre-filter, two sanitizing modules, and one PCO panel. Adapter must be ordered together with Terra WhisperFlow FFU.
