Energy Saving Interior Air Curtain Compensation Fume Hood

Model: JH-FC043

Applications: Laminar air curtain ventilator has a breakthrough patent. Laminar air curtain
technology provides extremely safe “zero leakage” safety performance, which reduces
the energy consumption of air conditioning system by 80% compared with the existing
ventilator technology. It is the first and only ventilation cabinet in the world, which can
not only ensure safety, but also greatly reduce energy consumption.

Main advantages: The world’s first and only patented laminar wind curtain technology
has brought extremely safe “zero leakage” security performance (SGS-certified U.S.
standard testing). Compared with the traditional ventilator, the energy consumption of
air conditioning can be saved up to 80%. Highly intelligent design maximizes the safety,
energy saving and ease of use of the hood. Modular design ensures the simplicity and
uniformity of the structure of the ventilator.

At present, speed is the main index of the performance and safety of the fume hood
in the fume hood market, but this method is outdated. On the one hand, it wastes too
much energy of HVAC. On the other hand, when the fume hood moving door is open,
the negative pressure caused by the operator’s operation or movement at the moving
door will affect the inside of the fume hood. The gas causes interference, which makes
the fume hood in a very unsafe state. Our company’s patented laminar flow air curtain
technology breaks the traditional idea that the fume hood relies on the surface wind speed
to suppress leakage, focusing on creating an ideal laminar flow push-pull airflow movement
structure: the external air (outdoor air) is sent into the fume hood in the form of laminar flow
through the three supplementary air outlets of the fume hood, and there is a negative pressure
pulling force at the back of the fume hood. With this method, a stable air distribution can be
formed inside the fume hood, which can ensure the rapid and effective discharge of harmful
gases, thus effectively ensuring the safety of the experimenters.

Because of the laminar air curtain technology of our laminar air curtain fume hood, compared
with traditional fume hood, the total exhaust volume of our fume hood is reduced by 40%. Among
them, fresh air supplied from outdoor is 70% of the total exhaust air, and the remaining 30% is
indoor air. Compared with the traditional fume hood, the amount of air discharged from the room
is 18%(60%*30%=18%) of the traditional fume hood, which saves 82% of the energy consumption
of indoor air conditioning.

The top and bottom air supply ports of laminar air curtain fume hood form an effective air curtain
partition at the window opening, which protects the user’s breathing belt, and partitions the influence
of external disturbance on the airflow organization in the cabinet. The traditional fume hood operator’s
operation or dynamic movement at the moving door will interfere with the air distribution in the cabinet,
and laminar air curtain technology can minimize these interferences.
