A:  Thank you for your question regarding the AERN80K ventilation fan. This model requires 4" ducting which should not be reduced to anything smaller. Reducing the duct size will reduce the performance, increase the sound, and can cause premature motor failure. An elbow can be used, but it will add additional static pressure to the duct run and can also increase the sound and decrease the performance. There should be two feet of straight ducting before and after any elbow or bend that is used. We do not believe this is a motor issue at this point, but more of an installation issue. Please contact our Product Support team directly for more assistance at 800-637-1453.

A:  Thank you for your question regarding the AERN110K model. This model is 110 cfm's and designed for rooms 100 square feet or less. This would be suitable for a smaller room and we would recommend having enough make-up air to replace the air it is exhausting. This can be achieved by making sure the door is undercut about an inch or left open to allow the fan to pull fresh air into the room.
