Why using an enclosure with recirculating air filtration system?

When 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 (formely Enclosure for Toxics using Recirculating Air Filtration or ETRAF) equipped with a molecular filter.

Why choosing an enclosure LABOPUR® using recirculating air filtration?

Following its wide experience with safety cabinets and storage of dangerous products, ECOSAFE-leading manufacturer of safety cabinets-uses its entire technical knowledge to design and manufacture its fume hoods LABOPUR®. Made in EU, the fume hoods LABOPUR® stand out by a high manufacturing quality and finition. The entire process being controlled with the European standard ISO 9001 -2000.

Fume hoods LABOPUR® provide the user a secured work space for the repetitive manipulations of small chemicals quantities. The dangerous vapours are confined in the enclosure, then are cleansed while entering the active coal-based filter. Finally, dangerous vapours are rejected in the atmosphere without danger for the environment. Thus, the user's health is protected.

The LABOPUR® filter system is made of quality active charcoal according to your needs. It can be fit for a specific product. The active coal-based filters replacement requires only a few minutes.

Fume hoods LABOPUR® also allow you to save energy. Indeed, compared with enclosures with outside rejections, it is not necessary to heat or cool the incoming air. Furthermore the air in the room is cleaned.


NF X 15-211 French norm (September 1996):

NF X 15-211 French norm is the most demanding regulation today. It garantees to the user a full safety allowing him to focus on his manipulations.

Enclosures for toxic LABOPUR® using recirculating air filtration are classified according to 2 security levels:

- class 1 : enclosure with safety reserve
- class 2 : enclosure without safety reserve, the most common

Enclosures LABOPUR® using recirculating air filtration belongs to the class 2.

To be in accordance with this standard, fume hoods filtration LABOPUR have to meet multiple criteria (summary):

- the enclosure must be provided with a ventillation device to maintain the air speed with a rate between 0,4 m/s and 0,6 m/s.
- rejection, dowstream the filter, of 50% of the VME (mean value of exhibition) 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.
- the class 2 enclosures have to allow to treat products having a VME index superior or equal to 10 ppm.
- the class 2 enclosures have to be equipped with a sound or visual alarm activated every working 60 hours and also a sampling outlet device.
- the class 2 enclosures must not reject more than 50% of the VME downstream the filter during the detection test.

Certification :

Fume hoods LABOPUR® were approved according to the NF X 15-211 standard, by a independant laboratory, MAPE, itself approved by the COFRAQ. The COFRAQ accreditation gives evidence of the technical skills of the test laboratory by the highest european certification organisation.

LABOPUR® fume hoods are controlled according to quality process and procedures defined by the repository of international quality standard ISO 9001-2000, at the end of the assembly line and before their shipping to the user in order to assure a perfect functioning and efficiency.

Mean Value of Exhibition (V.M.E.) / Value Exhibition Limit (V.L.E.):

A chemical compound concentration in the air being able to be inhaled by a person during a determined duration without danger for his/her health is represented by a limit value (V.L.E.). Beyond this limit of time the user's health is in danger.

Mean Value of Exhibition (V.M.E.) : The V.M.E indicates the maximal concentration admitted for a given substance, in the workroom atmosphere where the user has to work on a 8 hours basis per day.

Value Exhibition Limit (V.L.E.).: The V.L.E. indicates the maximal concentration admitted for a given substance, in the workroom atmosphere to which the user may be exposed for a short period of time, lower or equal to 15 minutes (unless other indications).

The National Research and Safety Institute (I.N.R.S.) publishes a technical memo (n° ED 984) on the edge values of professional exposure to the chemical agents. This document is available, free of charge, on their website at the following address: and/or on our supplied manual's user CD-ROM.

What does active charcoal mean?

The active charcoal is a black powder with a porous structure. Manufactured from coconut shells, it has the property to occlude molecules emanating from dangerous products, due to the size of its micropores (less than 2µm).

Active charcoals manufacturing includes 2 steps:

- 1st. step: High temperatures burning and carbonization of the ingredients.
- 2nd. step: So called activation step, allowing to increase the coal absorption power.

Depending of the chemicals to be filtered, an "impregnation" can be added to improve the coal absorption ability. An impregnation for a given chemical can lead to an excellent absorption for a certain product but a disapointing result for another type of chemical.

After use, the coal powder may be cremated or regenerated by water steam treatment or acid or alkaline washes.

HELP US to protect and to respect the environment:


If the fume hoods LABOPUR protects at most the health of the users and their direct environment it is necessary to protect and respect the environment to insure the active coal-based reprocessing and the elimination of your filters charged with the toxics which you treated.
