Ductless Fume Hoods: A Cost Effective and Quick Solution for Increasing Bench Space
When additional operator protection from fumes and chemical vapors is required in the laboratory and space in conventional fume hoods is running low, a ductless (carbon filtered) fume hood can be a cost effective, suitable alternative.
When handling chemicals in the laboratory, it is imperative for the health of laboratory staff to avoid inhalation of potentially harmful substances and to work in an environment where the fumes and vapors are safely removed. There are two types of safety enclosures that may be used for safe laboratory handlings: Ducted Fume Hood or a Carbon Filtration Recirculatory Fume Hood.
The first choice for most people handling chemicals is to use a ducted fume hood – as these are oftentimes already installed in laboratories. However, in situations where additional extraction is required and space in fume hoods is running low, a ductless fume hood can be the easiest and most cost-effective solution.
How Does a Ductless Fume Hood Work?
Air is drawn from the laboratory past the operator and up through a filter system – removing particulates, chemicals – returning clean air back to the laboratory. The filter system can consist of up to three filters: Pre-Filter, Particulate Filter (Optional), Carbon Filter
Does Carbon Filtration Remove All Chemicals?
Answer: Most Chemicals* including ANY with a molecular weight above 30 and a boiling point above 60°C
*Some compounds, which do not fall into this bracket, are also well adsorbed because of their molecular size and structure.
To simplify this process, a Risk Assessment spreadsheet can be provided for your completion and an evaluation will be made according to your uses and the suitability of a ductless fume cabinet will be considered for your applications.
What Makes this Solution so Cost Effective and Quick?
Ductless Fume Hoods are shipped and delivered as a pre-calibrated, flat-pack shipment and can be assembled in a very short amount of time (approximately 1 hour) and used immediately following the settlement of airflows – whereas, conventional fume hoods require extensive hours of installation and costs associated. Thus, further reducing the Efficiency and Effectiveness of conventional fume hoods.
Key Features of Ductless Fume Hoods:
• Touch-Button On/Off Control Panel: Service Due Indicator and Audible Low Airflow Alarm
• Unobstructed Views: 360° Vision
