CDA 400 x 1D straight through Silencer

400mm dia x 400mm long straight through silencer (generally reduces a fan noise level by 7 – 10dB (A)* Can be supplied to either bolt directly to any manufacturer of cased axial or with spigots to mount inline with ducting.

The addition of this silencer to a system will act in the same way a silencer does on a car, so if you’ve ever heard a car with no silencer fitted, this gives you an idea of the impact a silencer can have on a system.

Please Note — for a straight through silencer to work to have the maximum impact on a system, a silencer should be fixed either side of the fan, this will give 3 benefits to the overall noise level of the system.

1. System side (usually the noise level inside a building) noise level is reduced

2. Atmospheric side (usually the noise level outside a building) noise level is reduced

3. The breakout from the fan is reduced, this could be a big factor depending where the fan is fitted, such as a false ceiling in a class room or office area

*Noise is a complicated medium to get right, if in doubt or you have specific target levels to achieve, please contact us via any means you feel comfortable with and we’ll find a solution to your problem
