Ductless Fume Hood
Portable Ductless Exhaust Hoods are negative-pressure turnkey hoods ventilate and purifies fumes, excellent choice for laboratories.  These hoods creates the negative air pressure that pulls contaminated air up and away from the operator’s breathing zone.  The air is directed into the filter chamber which houses various filter media (HEPA / Carbon) dependent on the type of particulate / vapor is generated.

Ductless exhaust hoods are available in width of 24", 32" models feature 1250 CFM impeller blower . Fan filter housing and work surface are constructed from corrosion resistant polypropylene. Walls are available in choice of clear Abrasion Resistant Polycarbonate or Static dissipative PVC. Static-dissipative surfaces minimize the risk of ESD electrostatic discharge under the hood. Polycarbonate AR offers abrasion and chemical resistance along with the same properties as regular Polycarbonate material.

Cleatech ductless exhaust hoods are a good choice if a ducted/ vented hood can not be installed. Ductless exhaust hoods work differently than vented hoods.
Similar to other ductless hoods, Cleatech  ductless fume hoods will not work without clean air filters HEPA or ULPA.
Activated charcoal filter is an option and the most common filtration media which absorb chemicals and odors.

Cleatech recommends a thorough testing of filter performance prior to exhaust release for each application.
