Sentry Air Systems Ductless Fume Hood – Deluxe Hood Model

Sentry Air Systems ductless fume hoods are high-quality portable units that protect lab workers and samples. These units are designed for use in locations that do not have access to outside ventilation. Air is recirculated through high-efficiency air filters eliminating the need for external ducting or venting. The deluxe model hoods have additional features such as LED lighting, hour counter, pressure reader, and upgraded hinges.



• Adjustable LED light
• Upgraded Hinges
• Variable speed controller
• Acrylic hood material
• Hour counter
• Pressure reading
• 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
Note: There are some low molecular weight substances that may not be appropriate for a ductless fume hood. In addition, certain high workload conditions may require external ducting.
