Ductless Fume Hoods

Ductless Fume Hoods for Facilities Where Ducting to the Outdoors is Impractical These units offer filtration systems that handle finite quantities of non-explosive solids, liquids, fumes, gases and nanoparticles. Additionally, Germfree Ductless Fume Hoods with HEPA exhaust filtration also function as Biological Safety Cabinets (BSC). While conventional fume hoods are ducted to the outdoors, certain existing facilities make a ducted fume hood to the outdoors impractical or otherwise costly. Germfree’s Ductless Fume Hood presents the solution to common infrastructure challenges.

Multi-stage Filtration:
Germfree’s Ductless Fume Hoods utilize a multi-stage filtration system that captures a diverse range of airborne contaminants from the work area and returns purified air into the room. The unit is set up with the properly configured combination of filtration modules for your application.

Aerosols, dust and nanoparticles are removed with a combination of prefilters, HEPA filters and ULPA filters.

Fumes and Gases:
Fumes and gases are removed with a two-stage Carbon Composite Module. Each module is supplied with the designated combinations of adsorptive, chemisorptive and reactive agents required for your application.

Filter Life of the Carbon Composite Modules:
The carbon filter life is determined by the selection and quantities of the adsorptive and chemisorptive materials used in relation to the quantities and concentrations of the chemicals to be adsorbed in your application. The adsorption properties/capabilities of carbon are well established allowing approximate filter life to be determined prior to operation. The Carbon Composite Module can also be monitored during use and Germfree will help you determine the proper selection of gas monitors.

Chemically Resistant Construction:
Germfree’s Ductless Fume Hoods are designed and engineered to handle the rigorous demands of your application. The interior and exterior of our Ductless Fume Hoods are coated for resistance to chemicals. All stainless steel models are also available.
Ductless Fume Hoods for Mobile Labs:
Germfree is a leading manufacturer of mobile laboratories. Ductless Fume Hoods have been installed into various Germfree truck and trailer based platforms. Germfree's Ductless Fume Hoods are field-tested making them suitable for the most demanding environments. Germfree is the only company with global experience in installing ruggedized mobile biosafety cabinetry, ensuring your Ductless Fume Hoods can be deployed wherever they are needed. Additionally, Germfree products utilizing HEPA, ULPA and carbon air filtration are designed for ease of performance testing and certification when required.
