Sentry Air Systems Ductless Fume Hood – Advanced 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 Advanced Model hood offers the most features in the ductless fume hood line. It comes with automated airflow control, real-time average airflow, room condition monitoring, accumulated run time, and a real-time pressure display.



• Auto Sentry automated airflow control
• Adjustable LED light
• Upgraded Hinges
• Variable speed controller
• Carbon steel hood material
• Real-time average airflow
• Room conditions (temperature and humidity)
• Accumulated filter runtime
• Real-time pressure display
• 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.
