The difference between the net air type fume hood and the ordinary fume hood

April 02, 2024

As more and more laboratory users begin to choose ductless fume hoods, Taicang Huafeng Technology is specialized in producing ductless fume hoods. The net gas storage cabinet manufacturers summarize the following new fume hoods and traditional fume hoods. the difference:

1, whether it is efflux:

The air-purifying fume hood does not require an external pipe, and has a built-in fan and a filter to directly extract and filter the exhaust gas;

Ordinary fume hoods need to be piped to the outside, and the fan is usually placed on the roof;

2, the amount of work:

One piece of equipment of Huafeng Clean Air Fume Hood can be installed in half an hour, and can be used by plugging in the power supply;

Ordinary fume hoods need to start from the design, drilling, installation, laying pipelines, roofing fans;

3, energy consumption:

Huafeng clean air fume hood power from 30W-120W, energy consumption is almost negligible;

The power of ordinary ventilation cabinet fans ranges from 1500W to tens of thousands of watts, and the energy consumption cost is huge;

4, air conditioning wind consumption

Huafeng clean air type ventilation cabinet circulates inside, no need to discharge air to the outside, no need to add air conditioning equipment and consume air conditioning wind;

Ordinary fume hoods discharge indoor air-conditioning air according to different exhaust air volumes, and need to add corresponding air-conditioning equipment, which may cause indoor negative pressure and affect the working environment;

5, noise

The Huafeng Clean Air Fume Hood is only 41 decibels. It is very quiet and does not have any impact on other operations in the laboratory, and can guarantee the accuracy when weigh one hundred thousandth of the balance;

Ordinary fume hoods have large noise and vibration, and cannot be weighed by the balance;

6, the service life

A Huafeng clean air fume hood can be used for more than 10 years under non-extreme conditions, and it is easy to move, and the laboratory can be reused;

Ordinary fume hoods are prone to aging, and retrofit labs are not suitable for reuse;

7, maintenance

Huafeng fume hood is easy to maintain, just check the line and switch, etc., easy to check;

Ordinary fume hoods involve the design of the ducts, lines and air ducts of the entire building. If there is a problem, it is difficult to check and it is difficult;

Most of the above are the advantages of the clean air fume hood. Of course, the common fume hood also has the advantage that the new fume hood can't match.

1, applicability

Ordinary fume hood can be adapted to any dose, experimental operation at any frequency;

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

2, consumables cost

The net gas type fume hood has some consumables costs, although it can completely offset the energy consumption of the fume hood, and can have a balance;

There is no consumable cost after installation of the common fume hood;

In summary: users can choose the right products according to the laboratory conditions, Taicang Huafeng Technology will serve you wholeheartedly!
