Traditionally, the term ductless fume hood meant a fume hood with a specific type of filter to trap and contain certain types of chemical fumes and particulates. Those traditional ductless fume hoods are still available, though their application is limited. However, in the last 10 years new filtration technology has radically improved the ability to trap and neutralize contaminants. New electronic monitoring technology has vastly improved the ability of chemical filtration fume hoods to safely monitor chemical saturation and filter replacement. Since the chemical fumes and particulates are bonded to and neutralized by the filters they are technically safe to discard. However, as an added precaution we recommend incineration which converts the carbon filter into carbon dioxide.
Interested in Going Green? Not only are ductless/filtered fume hoods safe, they also are a very Green solution since they drastically reduce the energy consumption of the HVAC system. The organization saves while protecting the environment as well as reducing the carbon footprint of the lab building. Safety, Saving Energy, Reducing Costs & Saving the Environment – What more could you ask for?
Employing the newest filter construction and fume hood monitoring technology, Ductless Fume Hoods provide an eco-friendly solution that will save your laboratory up to $6,000 in energy savings annually. How? Air is filtered and cleaned in the hood and exhausted back into the room rather than exhausted out of the building. Building make up air requirements are reduced substantially saving money in heating and cooling costs not to mention upfront capital costs of ductwork, HVAC systems and exhaust blowers.
Since no ductwork is required, ductless fume hoods are ideal for temporary applications or where mobility or shared use is required. The hoods can be mounted on carts and wheeled from lab to lab or researcher to researcher.
Tired of the long downtime and expense adding ducted fume hoods into an existing facility? Infrastructure and installation downtime has been drastically reduced since there is no complicated and expensive exhaust system connected to the fume hoods, plus the HVAC system can be significantly downsized. Many installations are done in one day. Moreover, building operations and maintenance staff will not have to be experts in VAV technology and procedures since most of the VAV controls and dampers can be eliminated with ductless/filtered technology. Plus, by eliminating or drastically reducing an expensive HVAC system, there is less HVAC equipment to break down, saving you money.
They feature digital display of face velocity and filter saturation levels, post-less corner construction for better viewing, and are equipped with secondary safety filters and removable plastic spill tray for easy cleanup. These units exceed the requirements of OSHA, Z9.5, and ASHRAE performance standards.
