PRICE SMX-FR
Series of louvered high induction directional diffusers are
Fire-Rated Assemblies listed in the UL Listed (Underwriters Laboratories Fire Resistance Directory) and ULC Listed (Underwriters Laboratories of Canada Equipment and Materials Directory). This design meets time versus temperature test criteria and NFPA 90A requirements.
The SMX-FR
Series of louvered high induction directional diffusers are specifically designed to solve difficult high cooling load problems in places such as perimeter zone office spaces, auditoriums, convention centers, meeting rooms, restaurants, health care facilities, etc.
Internally mounted discharge vanes are engineered to create a high rate of induction that will rapidly mix warm room air with the cool, conditioned supply air. This rapid mixing (induction) quickly equalizes the temperature differential between the two air masses, thus minimizing the chances of uncomfortable drafts when dealing with large air volumes. |
