PERFORMANCE AND COMPLIANCE
Tests prove it.
Erlab filtration is the most efficient solution for your laboratory.
Afnor NF-X 15-211. The most demanding standard to the world for recirculating fume hoods.
Mandated by AFNOR, the Union de Normalisation Mécanique (UNM), composed of a college of experts in ventilation, public bodies, members of professional unions, has established the standard AFNOR NF X 15-211: 2009. This standard applies to fume hoods (also known as recirculating fume hoods or ETRAFs) designed for all laboratories in which chemical agents subject to an occupational exposure limit value (OELV) are handled.
This standard requires performance criteria related to filtration efficiency, enclosure containment efficiency, face velocity and documentation.
It refers to the capacity of the filter to retain the harmful molecules handled in the enclosure and guarantees the quality of the air recirculated downstream of the filter.
Filtering fume hoods
The effectiveness of enclosure containment.
It defines the capacity of the fume hood to maintain the vapors or particles in the enclosure without them being able to disperse in the laboratory environment.
Filtering fume hoods
It refers to the ability of the fume hood to create a dynamic barrier between the manipulator and the handling. For fixed front filtration hoods, the front air velocity at any point of the openings must be between 0.4 and 0.6 m/s. Fume hoods must also be equipped with a continuous ventilation monitoring device.
Documentation: « The Chemical Listing ».
Filtration fume hoods must be accompanied by a booklet containing an exhaustive list of the chemical agents, that the manufacturer certifies, can be handled in the fume hood under the conditions described in standard NF X 15-211: 2009, indicating for each of them :
• The name of the chemical agent, its formula, its CAS number, its boiling point, its molecular weight, its vapor pressure, etc.
• The reference of the adapted filter and its retention capacity in accordance with the NF X 15-211 standard.
• The type of air quality monitoring recommended to control filter efficiency
• The name of the test laboratory that performed the type test.
The result of 50 years of research and development related to filtration technologies, this vademecum is a testament to Erlab’s expertise in molecular and particulate filtration. In compliance with the AFNOR NF X 15-211: 2009 standard, this document, delivered with each fume hood, includes an exhaustive list of the chemical agents, that Erlab certifies, can be handled in the safest possible conditions.
