Low sound levels
Lower total installed cost than conventional Ducted Fume Hoods
Avaliable with Carbon/Toxic Vapour removal and HEPA filtration for a large variety of applications
Many chemical processes can be carried out using Ductless or Filtration Fume Hoods which provide
a flexible solution to problems ducting harmful chemical vapours away from the laboratory. These
Hoods offer a cost effective solution to these problems, save energy and eliminate the release of
harmful chemical vapours into the outside environment. They also safeguard the health of laboratory
staff by preventing toxic and often carcinogenic vapours being inhaled. The Staftech range of Fume
and Containment Hoods have been designed to satisfy the requirements of Brithsh Standard 7989
and other International standards which requires an air velocity through the front opening of 0.5m/sec.
This velocity is deemed by internation experts as being necessary to ensure containment of the harmful
aerosols generated within the cabinet enclosure. This air is drawn over the work area and up through
the pre-filter, carbon filter and discharged back to the laboratory. For some applications it is necessary
to work with low risk biological material and also a combination of both biological and chemical materials
Special HEPA and HEPA/Carbon combination filters are available for these applications.
