Ductless hoods recirculate air


Purair ductless fume hoods provide operator protection when using hazardous substances. A face velocity at 100 fpm ensures containment of fumes, and an alarm alerts users when the airflow falls to an unacceptable level. The units operate at low noise levels and recirculate air so as not to exhaust expensive conditioned and/or heated air into the atmosphere. All mechanisms in the head section are located on the clean side of the filter, preventing contamination. The main filter can be chosen from 14 different types of carbon, which include specialty media for vapors of organics, solvents, acids, mercury and formaldehyde. HEPA filters for particulate filtration are also available.


Smart Use of Energy“High-efficiency SplitCool DC18 units will dramatically lower the total system cost for running an air conditioner from solar panels, by eliminating the bulk of installation work required by competitive units and by using fewer solar panels and a lower battery requirement,” said John Williams, chief operating officer, Solar Panels Plus. “Unlike the SplitCool DC18, most normal air conditioners simply turn on and off based on the thermostat, and this normal ‘on-off-on-off’ approach is very wasteful of electricity because it is not always necessary to run the compressor at full speed.”

  2. HVAC ductless systems have a more stylishly satisfying appearance than other extra units, for example, window climate control systems. Most are just 7 inches wide and have a smooth external appearance.
