APPLICATIONS
The breeding and holding of Specific Pathogen Free ( SPF ) animals demands an environment which is free from contamination in the form of bacteria, viruses and parasites, known to be a significant factor in the incidence of infection in laboratory animal colonies. Immuno-suppressed animals such as nude mice must be kept in ultra-clean conditions.
Gelman SPF Series Ventilated Animal Storage Systems have been developed to meet the needs of :

• Providing an environment free from airborne contamination in the form of bacteria, viruses and parasites, suitable for the breeding and holding of Specific Pathogen Free ( SPF ) or immuno-suppressed
• Providing a controlled environment where airborne contaminants from the holding animals such as infected faeces, urine, fur, sawdust and aerosols are arrested and contained with no cross contamination between each cage or compartment.
• Providing an extremely cost-effective alternative to the construction of a dedicated room.

Gelman SPF Series Ventilated Animal Storage Systems protect animals but do not contain hazardous aerosols, which may be released from infected animals.
Gelman SPF Series Ventilated Animal Storage Systems should be used for applications involving the holding of Specific Pathogen Free ( SPF ) or immuno-suppressed animals.
Gelman ACU Series Infected Animal Containment Systems should be used in infected animal holding applications.

DESCRIPTION
Gelman SPF Series Ventilated Animal Storage Systems with microprocessor-controlled diagnostic system are compact, self-contained “100% exhaust” mobile enclosures which consist of a HEPA filter / fan module and a cage storage compartment with adjustable shelvings
Units incorporate separate HEPA filter / fan systems to enable fine adjustments and air balancing for the supply and exhaust air systems.
A direct drive centrifugal fan draws in ambient air through an easily accessible prefilter on top of the enclosure to remove gross particulates of 5 micron and larger.
The prefiltered air is biologically-cleaned by a HEPA filter which arrests all particulates and biological matters down to 0.3 micron for animal protection.
The ultra-clean air is introduced at a low velocity across the full length of each cage. The gentle horizontal airflow pattern “bathes” the animals, greatly reduces the concentration of airborne contaminants and provides more efficient ventilation and drying, thus lowering the ammonia and carbon dioxide levels. Additionally, the constant displacement of air from the compartment prevents entry of ambient contamination.
Airborne contaminants released within each cage are filtered by an exhaust HEPA filter and an exclusive HMZD molecular carbon filter before the air is discharged back to the laboratory.
The contaminated air is drawn to the exhaust system with no exposure or cross contamination of other animals in the same holding unit.
An exhaust transition adaptor complete with flexible duct for connection to the building exhaust system can be provided for total exhaust to the outside atmosphere.
