Product Description

A traditional fume hood is generally connected to a building HVAC System and relies on this system to remove hazardous fume from the laboratory. A ductless fume hood, as the name suggests, is a fume hood that does not depend on an exhaust system similar to an HVAC. Rather it filters fume through a set of filters attached to the unit.The chemical range is limited by the type of filter being used inside the fume hood. Depending on your application the filter may need to be swapped out to meet the purification needs. HEPA, ULPA, Activated Charcoal Carbon for General Purpose, and Activated Carbon for Acid Gasses filters are available.
As the name suggests, a ductless fume hood is not attached to a buildings HVAC system. Instead, a ductless hood moves contaminated air through HEPA (High-Efficiency Particulate Air) or ULPA (Ultra Low Particulate Air) filters and push the purified air back into the lab.

Ductless fume hoods are used in various fields. Some of the most common applications are the following:

• Life Sciences
• Forensics, Fingerprinting and DNA
• Educational Purposes
• Clinics and Hospitals
• Dental Laboratory
• Cleanrooms
• 3D Printing
• Archaeology
• Glass Manufacturing
• Mycology
• Soldering
• Pharmaceutical
• Art Restoration
• Production of Glues, Paints, and Solvents

A ductless fume hood is contained ventilation equipment or working space that filters out chemical airborne materials and recycles them back to the working environment as breathable air. It uses activated carbon filters to clean the fumes. Ductless fume hoods usually have a frontal airflow to get the air out at a controlled rate to prevent the harmful gases from going out of the workstation.

Unlike, a traditional fume hood, air is purified through filters at the top of the unit and pushed back into the laboratory, this has two drawbacks. A HEPA filter will capture up to 99.97% at 0.3µm particles, this leaves 0.03% particles recirculated back into the laboratory. If the application being worked on is releasing extremely dangerous fume working for a period of time can cause injury lab personnel

Once it has gone through the pre-filter, it goes through the main filters, where other particulates are thoroughly removed. Then, the air goes out from the main filter to the workstation as breathable air.
