Gentle-Air: "How Air Flows Through the System"

The airflow within the Gentle-Air Ventilated Rack System® is divided into two (2) areas; airflow through the rack, and airflow through the cage.

Rack Airflow Airflow through the Rack
In positive isolation, the air moves through the blower, and is pushed into the Lower Supply Plenum via a coarse particle pre-filter and the supply HEPA filter. It then fills the Lower Supply Plenum and rises into the Vertical Supply Plenums. The air enters the cages through the supply portal, is distributed downward to the cage floor, pushing the warm moist up and out through the exhaust portal into the Vertical Exhaust Plenums. The exhausted air moves upward into the Upper Exhaust Plenum and exits the unit via the Exhaust HEPA assembly.

 



Airflow through the Cage Airflow through the Cage
HEPA filtered supply air enters the cage at the top. As it enters, it is deflected down and to the front by the angle on the vent door. Moving through the bedding and animal environment, the air accumulates moisture, gases and heat. This warmer air rises to the top of the cage where it is forced out through the exhaust vent door and air valve into the Vertical Exhaust Plenum.

 

Gentle-Air delivers 60-90 AC/H.
Typically, all that’s needed is between 60 to 90 air changes per hour to remove the gases and moisture from the micro-environment. You select from three fan speeds the number of air changes based on the load on the rack’s filters and particular needs of your facility. Most facilities using the Gentle-Air system average about 70 AC/H.
