Why Go For Ductless Fume Hoods?

Ductless fume hoods or conventional chemical fume hoods? Why nowadays most people in the industries choose ductless fume hoods? Any problems with conventional chemical fume hoods? The answers are here. There are some advantages to use ductless fume hoods compare with the conventional fume hoods. Read more to know why ductless fume hoods become famous and first choice in the industries.

Ductless fume hoods are a portable unit. There is no connection to the building structure beside the power cord. It is easy to move or relocate your ductless fume hoods to any place that you want.

To relocate or shift the conventional chemical fume hoods is not easy. You cannot do it yourself. You need third party or contractors to move the fume hoods to other location. It needs time and proper planning especially when to design the new ducting layout and also doing new ducting installation. The new location must be accessible to the building exhaust system. That is why people in the industries prefer ductless fume hoods.

In term of cost, ductless fume hoods is cheaper compare with conventional chemical fume hoods. The operation and installation cost of ductless fume hoods (also known as HVAC-free fume hoods) is substantially lower than that of a conventional fume hoods. No cost for ducting installation for ductless fume hoods. No building exhaust fan connection needed. No blower need to purchase. See, how much we can save by using ductless fume hoods.

This unit type installed with automatic controller to monitor airflow and filter condition constantly to ensure the safety of the operators. Each unit of ductless fume hoods has a solid state gas detector. Its function is to monitor the carbon filter bed for saturation. The ductless fume hoods are also installed with alarms that audible and visible to alert the operators of filter saturation. The alarms already set per current ACGIH standards for TLV of known chemicals. State-of-the-art airflow sensor takes a constant reading of face velocity. Then, it will provides information in linear feet per minute (LFM) on the LCD monitor screen that the operators easily can monitor. So, ductless fume hoods are safe for you.

Once the bonded carbon filter saturated, it can safely disposed of in a landfill. For the conventional chemical fume hoods, the room air will be processed in the room and release to the environment. This process may release the air together with the harmful fumes and vapors which will harm the environment. So, ductless fume hoods are the best for the environment.
