No, there is not, but some are quieter than others, and when they're set up and in step right they are much less noisy than they are when something's not quite right, or when they're wearing out.

If you read the companies' ad, all their pumps are incredibly silent. The people who write those ads are any lying or deaf.

Answers:    Yes their is,I've got a Renna air 50 and Renna air 30
and both are immensely quiet.The price of these is not bad,
and good efficacy for your money,and last for years.
I use the small one for air stones etc,the other for
my gravel cleaner.
Good Luck and a Merry xmas.
