Description

PRODUCT: DUCTLESS FUME HOOD

PRODUCT: DUCTLESS FUME HOOD

When you are using chemicals, your health might be in danger due to the emanation of harmful and toxic vapours. To protect yourself and your close environment, you must manipulate your products in an enclosure using recirculating air filtration (formerly Enclosure for Toxics using Recirculating Air Filtration or ETRAF) equipped with a molecular filter or either particulate filter (HEPA filter) or both filters.

The ductless fume hoods from METHOD provide the user with a secured workspace for the repetitive manipulations of small chemicals quantities. The dangerous vapours are confined in the enclosure, then are cleaned while entering the active charcoal filter. Finally, dangerous vapours are rejected in the atmosphere without danger for the environment. Thus, the user’s health is protected.

The ductless system head and filter by METHOD are tested to the following NF X 15-211French norm- May 2009. NF X 15-211 French norm is the most demanding regulation today. Enclosures for toxic using recirculating air filtration are classified according to Class 2 security levels:

  • class 1: an enclosure with a safety reserve
  • class 2: an enclosure without a safety reserve, the most common

PRODUCT DETAILS

PRODUCT DETAILS

METHOD Ductless Fume Hood belongs to class 2:

  • P type: particle filtration
  • VP type: vapors
  • PV type: particle & vapors filtration

METHOD ductless fume hoods are recirculating air filtration enclosures from class 2 which could be fitted, depending on the model, with filter for particles or for vapours or both. To be in as per this standard, air filtration fume hood LABOPUR® have to meet multiple criteria, for instance:

  • The enclosure must be provided with a ventilation device to maintain the airspeed with a rate between 0.4 m/s and 0.6 m/s.
  • If Class 2, Rejection, downstream the filter, of 50% of the VLEP (occupational exposure limit value) of toxics treated in the enclosure in the duration of normal filter use.
  • The enclosure must have been tested by an approved and independent laboratory.
  • If velocity alarm not provided, the class 2 enclosures must not reject more than 50% of the VME downstream the filter during the detection test.

Activated carbon is an extremely porous black carbon allowing the absorption of molecules from chemicals thanks to the high degree of microporosity (less than 2 μm). Based on the chemicals to filter; activated carbon can be impregnated to improve the absorption capacity. A specific impregnation could fit for one product but not for all.

PRODUCT CERTIFICATION
