What is the ISO 1600 dB? At low and max use?

3 answers

Don't know db but external motor extremely quiet . We are very happy with it . I'm sure Schweigen would be bale to give you details of actual db .


I don't know either. You can hardly hear the outside motor. It's worth every cent.

Hi Joe,

Unfortunately, we cannot provide you with an exact decibel reading, the reason for this is that each installation is unique and there are numerous factors which can affect the decibel reading.
Some of these factors include:
- Length of ducting
- Number of bends
- If there has been any ducting kinked or crushed
- Position of the ducting
- Position of the motor
- Uncontrollable external factors
- What the motor is mounted to (materials)
They are however a lot less noisy than any standard air conditioning unit. When installed correctly, on the lower speeds you will not be able to hear the unit, on the higher speeds you may hear some wind noise which is just the motor running very fast.

Thank you
Haley, Marketing Co-ordinator @ Schweigen




Can anyone tell me the DB on their silent schweigen range hood? Probably looking at the external motor for the 1600m3

No answers



We are thinking of purchasing UM1170-6ST single external motor, 900m3/h. We will need to wall mount it but are worried about noise of motor (as it will be near bedrooms) How many decibels is the motor?

Hi Sue, I wouldn't have a clue. Probably best to phone schweigen. Cheers

What is the cfm flow of the various Schweigen undercount models?

2 answers

The flow rate depends on which motor is chosen. I recommend the dual motor outlet. Details can be found at the following link



I agree with the above answer. Couldn't say what the flow is in cfm as Australia has been metric since 1973. I use the 1600 cubic meter per hour external motor, which is sufficient on the middle setting. As Brian says, you could go the two motor option for increased flow.
