APPLICATIONS
Gelman Versaflow VSF Series Filtered Fume Enclosures with its exclusive dual-HMZD carbon exhaust filtration system are designed to provide a high degree of personnel and environment protection from odours or unsafe concentrations of chemicals, vapours and aerosols in the laboratories using the latest molecular filtration technology.
The Gelman Versaflow VSF Series filtered fume enclosures are suitable for handlings of large quantities of chemicals due to its high chemical retention capacities and are ideal for use with large apparatus or laboratory equipment.
The Gelman Versaflow VSF Series filtered fume enclosures:

  • -can be operated as a console unit or joined together to form continuous runs of fume-containment rows.
  • -can be used as:
    1. non-ducted filtered fume enclosure in the ‘recirculatory’ mode.
    2. ‘ducted’ fume enclosure without filtration.
    3. ‘filtered/ducted’ fume enclosure in the combined operational mode.
  • -can be converted to filter organic solvents, acid gases, formaldehyde, ammonia, radioactive iodine and other specific gases when installed with the correct HMZD molecular carbon filter without changing or modifying the unit.

The Gelman Versaflow VSF Series filtered fume enclosures are extensively used in laboratories including clinical diagnostic testing, biological and medical research, analytical chemistry, quality control, biotechnology, cosmetic, photographic as well as in the food, petrochemical, pharmaceutical and electronic industries.

 

OPERATION
The Gelman Versaflow VSF Series filtered fume enclosures maintain an average inflow velocity of 100 fpm through the work access opening.
An effective air barrier between the operator and the work zone, maintained by an inward flow of room air into a full-width work access opening provides personnel and environment protection.
The barrier air blends with the contaminated work area air and is directed through an easily accessible prefilter on top of the work zone to trap large particles.
The prefiltered air passes through a dual-layered composite filter cells, comprising of main and security backup HMZD molecular carbon filters.
The main HMZD filters remove odours and toxic chemical contaminants released within the work zone and the air is totally exhausted to the laboratory or outside atmosphere after final filtration by secondary or security backup HMZD filters. The security backup filters provide a fail-safe measure to prevent any unfiltered gaseous contaminants from escaping in the event that the main filters failed or are saturated.
