Ductless Fume Hood

Ductless Fume Hoods, manufactured by Sentry Air Systems, offer a portable, easy-to-maintain solution that protects your lab personnel from harmful types of carbon, airborne fumes and chemicals. Typically used in locations where outside ventilation isn’t possible or will be costly to install, the ductless fume hood produces a recirculating air pattern filtered through high efficiency air filters and requires no external ducting or venting.

What is a Ductless Fume Hood?

A ductless fume hood is a stand alone, compact workstation that provides a continuous flow of air that filters hazardous fume vapors out, recirculating clean air back into your working environment. Because the air is recirculated, no exterior ducting or makeup air is necessary. These air filtration systems are designed to keep harmful airborne contaminants away from the operator's respiratory zone while they work within the hood.

Also referred to as exhaust hoods, these containment systems are used for a variety of applications including chemical fume control, powder and dust removal, solvent vapor control, pharmaceutical powder filling, light grinding, acid gas fumes, anesthesia gas containment, epoxy fume control and other applications that produce hazardous particulates and fumes.


How does a Ductless Fume Hood work?

Ductless Fume Hood

Ductless Fume Hood vs Ducted Fume Hood

Ductless fume hoods offer several key advantages when weighing your options versus a ducted fume hood:

  • No costly ducting or venting
  • No permitting issues for venting outside of the building (ie. EPA air sampling)
  • Adaptable (mobility and ease in change of layout)
  • Environmentally friendly
  • Significant energy cost savings

However, a ductless fume hood may not be suitable for the application being practiced as there are certain features of a ducted hood that may suit your needs more:

  • Certain chemicals/gases carry a low molecular weight and are not efficiently captured through a carbon filter (ie. methane, butane, propane gas)
  • Loading: the amount of uses per time frame may require us to directly vent outside versus running through a particular filter “too much”
    • For example: If your application is using acetone gas and evaporating gallons per day, running it through a carbon filter in excess may saturate it past an effective point, rendering it to be useless or replaced at a significant rate.
  • Dangerous chemicals that need to be vented outside per regulations of OSHA. NIOSH


Benefits of a Ductless Fume Hood

  • Minimal installation costs—no external ducting or venting
  • Portable
  • Minimal maintenance
  • Environmentally friendly
  • Significant energy cost savings
  • No permitting issues for venting outside (ie. EPA air sampling)


Fume Hood Safety Considerations

Safe operation of your fume hood is critical to protecting your staff and anyone around it. A ductless fume hood should only be considered for use in labs with low hazard chemicals.

  • They should be visually inspected frequently
  • Pedestrian traffic in front of the hood should be limited
  • Any bulky equipment should be placed at the rear of the hood
  • To allow for airflow, large equipment should be raised at least 2” off the surface
  • If your fume hood is used often, a regular cleaning schedule should be established

Sentry Air invests in certification processes and independent testing performed by a Nationally Recognized Testing Laboratory (NRTL) prior to offering any air infiltration products.

Features and Benefits

Environmentally-Friendly: In many cases, ducted exhaust hoods empty extracted fume and particulate directly outdoors without sending it through a filtration system first. Ductless Fume Hoods trap hazardous particulate in filters so they can be disposed of properly.

Energy Efficiency/Cost Efficiency: Ductless Fume Hoods recirculate existing room air, while externally ducting systems remove heated, cooled, or dehumidified air outdoors, which requires that air to be replaced. This has the potential to waste energy and increase cost.

Minimal Maintenance & Installation Requirements/Easy Mobility: While externally ducting exhaust hoods require complicated installation because of ducting construction, Ductless Fume Hoods can be up and running with minimal installation. They are essentially “plug and play” solutions. Ductless Containment Hoods do not require any ducting or external venting and can be moved from location to location with relative ease. The only maintenance requirements are replacing saturated filters and wiping the hood down with appropriate cleaning supplies from time to time.
