| Dimmer for an aspirator (evaporative cooler) |
| (1/1) |
| woor90:
Hello, I have an evaporative cooler which is too noisy for the application I want to use it for, I'd like to ask if it's possible to use a dimmer for it in order to drastically reduce the noise. Of course I'm aware that decreasing the fan speed will decrease the efficiency of the device, but this is not a problem at all, it's already oversized. My issue is only the noise (around 60dB at minimum...). In particular I'm talking of this device: https://www.honeywellstore.com/store/products/evaporative-air-cooler-for-indoor-outdoor-and-commercial-honeywell-co60pm.htm I know there is also a water pump inside, but I can simply disconnect it and run it separately. Do you think it's a feasible workaround? Will decreasing the speed to 1/2 or 1/3 of the selectable lowest speed significantly decrease the noise? Which type of dimmer do I need? one for induction motors, right? Thanks |

The description says it has three speeds. Even the lowest is too noisy for you? |
| woor90:
Yes, it's too lout even at low speed. |

Get a ceiling fan speed controller. |

While an electronic controller might work you could try something simpler which is inserting a resistor in series (suitably sized in every respect). |
