Shanghai ductless fume hood

Product detailed description:

It belongs to the new generation of self-cleaning fume hood without pipeline installation, with built-in fans and molecular filters. By using molecular filters to adsorb and volatilize chemical gases, it is possible to efficiently purify the air inside cabinets and laboratories. Directly controlling the diffusion of chemical gases from the source has the characteristics of ultra-high efficiency purification, low energy consumption, small size, simple installation, and flexible operation, providing a safe and clean working environment for laboratory staff conveniently and effectively.

Probe+operation panel

The brand new design enables online detection of filter saturation and laboratory contamination status. The ultra large LCD screen displays in PPM units and adopts PID calibration from RAE company in the United States, with high accuracy, fast response, and strong stability.

Alarm point setting

Users can set appropriate alarm points on their own to improve the safety level of the laboratory.

The difference between clean air fume hood and ordinary fume hood

As more and more laboratory users begin to choose ductless fume hoods, manufacturers of clean gas storage cabinets summarize the following differences between new fume hoods and traditional fume hoods:

1. Whether to discharge externally:

The clean air type fume hood does not require external pipelines, but has built-in fans and filters to directly extract, adsorb, and filter exhaust gases;

Ordinary fume hoods require holes to connect pipes and discharge them outdoors, while fans are usually installed on the roof;

2. Quantity of work:

The Bi En Si clean air type fume hood can be installed in just half an hour and can be used by plugging in the power supply;

Ordinary fume hoods require starting from design, drilling holes, installation, laying pipelines, and installing fans on the roof;

3. In terms of energy consumption:

The power of the Bi En Si clean air type fume hood ranges from 30W to 120W, and the energy consumption is almost negligible;

The power of ordinary fume hood fans ranges from 1500W to tens of thousands of watts, with huge energy consumption costs;

4. Air conditioning air consumption

The Bi En Si clean air type fume hood circulates inside, without the need to exhaust air outdoors, add air conditioning equipment, or consume air conditioning air;

Ordinary fume hoods exhaust indoor air conditioning according to different exhaust volumes, requiring the addition of corresponding air conditioning equipment, which may lead to negative pressure indoors and affect the working environment;

5. Noise

The Bi En Si clean air type fume hood only has 41 decibels, which is very quiet and will not have any impact on other laboratory operations, and can ensure the accuracy of weighing with a scale of one hundred thousandth;

Ordinary fume hoods have high noise and vibration, and cannot be weighed using a balance;

6. Service life

A Bi En Si clean air type fume hood can be used for more than 10 years without special circumstances, is easy to move, and can be reused in the laboratory;

Ordinary fume hoods are prone to aging, and laboratory renovations and updates are not suitable for reuse;

7. Maintenance

The maintenance of the Biensi fume hood is simple, only requiring inspection of the wiring and switches, making it easy to troubleshoot;

Ordinary fume hoods involve various air ducts, wiring, and the design of the entire building's air ducts, making it difficult and challenging to troubleshoot any issues that may arise;

Most of the above are the advantages of clean air fume hoods, but of course, ordinary fume hoods also have advantages that new fume hoods cannot compare to

1. Applicability

Ordinary fume hoods can be suitable for experimental operations at any dose and frequency;

The clean air type fume hood is only suitable for small and medium dose operations;

2. Consumable costs

The clean air type fume hood has some consumable costs, although it can offset the energy consumption cost of the external exhaust fume hood and have some surplus;

After the installation of a regular fume hood, there is no cost of consumables;
