The Moody AFB wood shop requires a new dust collector system be installed due to a fire that damaged the outside unit.

This work would be a full replacement of the dust collector system to include a combustible dust and fire protection management system that meets current NFPA guidelines. All existing duct work must be replaced and redesigned to be efficient when collecting dust. This will also require the removal and disposal of the old unit and duct work and installation of all new equipment.
