What features allow ventilation blowers to be low-noise?
A. Tri-Mer ventilation blowers with direct-drive coupling motor set-up are an excellent choice for low-noise ventilation blowers. Tri-Mer ventilation blowers are manufactured from polypro or PVC, which is quieter, compared to metal. If the blower is large and pressure is high (10″ or above), an attenuator on the ventilation blowers outlet will help. Also, inlet and outlet ductwork can be designed so that noise is minimized. Also, if the ventilation blower can be moved away from a corner, or if dampening blankets can be added to the ventilation blowers housing, those things are helpful, too.
