Ductless (Carbon-Filtered) Enclosures

Paramount Ductless Enclosures (also known as ductless fume hoods) use carbon filters to rid the work area of hazardous fumes and vapors. Filters are available for adsorbing or treating acid gases, solvents, ammonia, formaldehyde and radioisotopes. Two types of carbon or one type of carbon and a HEPA filter may be stacked for mixed use applications in these ductless hoods.

FilterMate Portable Exhausters connect to Demonstration Hoods, XPert Balance Enclosures, Protector XVS Ventilation Stations or Protector Work Stations. Models are available that use a HEPA filter, carbon filter or combination of both filters to remove particulate and/or organic solvent, formaldehyde or ammonia vapors from the exhaust air. Protector Work Stations are designed specifically for the needs of histologists and pathologists. Models are available that use carbon filters that adsorb formaldehyde or organic solvent vapors. Other models duct to the outside. Fume Adsorbers are compact, portable enclosures that use a carbon filter to adsorb low levels of xylene and alcohol vapors.

Before you decide whether a carbon-filtered enclosure is appropriate for your application, fill out the Chemical Assessment form and submit it to us. A Labconco Ventilation Specialist will analyze your application and recommend the right enclosure for you.

Models Available

These enclosures use carbon filters and, in some cases HEPA filters, to protect users from exposure to hazardous fumes. No ducting is required.

Paramount Ductless Enclosures

These DH2 ductless hoods use stackable carbon filters to remove certain gases, solvents or radioisotopes. HEPA filters can be added to trap particulates. 

Fume Adsorbers

Low profile and portable, these enclosures are geared for light duty histology cover slipping and staining areas. Filters adsorb organic odors and noxious vapors.

Protector Work Stations

These enclosures are specifically designed for the needs of pathologists and histotechnologists. 

FilterMate Portable Exhausters

An accessory for a number of enclosures, these exhausters return carbon-filtered and/or HEPA-filtered air to the laboratory.
