Recommendation for air pump.

[Petia]

I have bought a cheap aquarium air pump to aerate nutrient solution for my indoor farm (no i m not growing illegal crops).

Although its in the kitchen my wife still complain its too noisy. Can some one recommend a silent, yet powerful air pump. If possible have at least 2 outlets. What brands should I look for?

Edit: bought a cheap hailea pump to replace my existing one. slightly less powerful but much more quieter.
