Supply fans may be either wall mounted or roof mounted. Most Buffalo fans and PRVs of the type described above are available for supply usage. Additional modifications and special products are available from American Coolair to tailor their usage to individual installations. For example, filters may be added to supply PRVs when desirable. Also, American Coolair's uniquely designed Model PT Power Tube Fan can be used to supply make-up air, in summer and winter, without the need for the supplemental heating required by most other make-up air systems. What makes Positive Pressure Ventilation superior to negative pressure?
* The risk of injury from the engaged structure is reduced while placing the fan in operation.
* Positive pressure ventilation is faster to set up and requires fewer personnel.
* The Positive Pressure Blower has a self contained power source, while electric fans require cords and adaptors.
* Smoke and heat is removed from all levels of the structure unlike negative pressure which can result in localized extraction.
* Quicker results. After initial knockdown, positive pressure ventilation can be initiated and will show immediate improvements in the interior conditions.
* It allows replacement of contaminants with vital cooler, cleaner air - especially in sealed or windowless buildings. It's also very effective in large and compartmentalized buildings, warehouses, schools, etc.
* Quick results allow firefighters faster entry due to lower heat levels and improved visibility.
