The UniFlow 21803 Conventional Fume Hood maintains constant air volume through sash opening, when equipped with the optional VAV system, face velocity can be controlled to meet specific requirements. The UniFlow 21803 measures 96"x24.25"x59" WxDxH and includes an explosion-proof vapor-proof light fixture Class I, Group C & D, Class II Group E, F & G electrical fixture installed but not wired, must be wired to comply with local codes. 115 volt, 60Hz AC. Switch not included.

Requires a remotely located exhaust blower.

UniFlow Conventional Fume Hoods VAV System Ensures Sufficient Airflow (Optional)

Maintain constant air exhaust volume at different sash openings while the face velocity varies at each sash opening. Closing the sash increases the the speed of incoming air, thus increasing face velocity.

The optional Variable Air Volume Control System constantly monitors face velocity and adjusts to a pre-set level regardless of sash position, ensuring sufficient air flow and maintaining volume to contain fumes even at
the near-closed sash positions. This system protects laboratory workers and reduces energy costs.

 
Complete Your Fume Hood Installation

Refer to HEMCO’s PLAN-A-HOOD to assist in the planning of your UNIFLOW Fume Hoods.

  • Ventilation Systems: Filters and Scrubbers
  • Variable Air Volume Controls (VAV)
    Systems allow fume hoods to reduce energy consumption while maintaining face velocity. The system operates by sensing actual face velocity and actuating a motorized damper or blower speed control to continuously adjust face velocity as sash is raised or lowered.
  • Ducting and Accessories
  • Airflow Monitors and Sash Stop
  • Plumbing and Electrical Services: Factory installed according to your exact specifications
  • Base Cabinets and Work surfaces

AirFlow Monitor  
Continuously monitors face velocity airflow of fume hood. Select and calibrate at desired FPM velocity set point. If the hood face velocity falls below the set point, an audible alarm sounds and a visual red indicator light appears. Airflow alarm is factory installed or can be field installed. 115 volt 60Hz 51406
VAV DAMPER CONTROL    
utilizes electronically actuated dampers within the ductwork to create and maintain optimal airflow. The VAV System includes the front mounted audio-visual alarm, electronic actuated damper controller and wall mounted sensor,transformer and calibration. Night set back, emergency air flow,mute of audible alarm, and self test mode are standard features of the unit.
