We are moving our shop to a new location and I'm trying to get our exhaust setup. Currently, we have 1 Penn state 1.5hp blower(https://www.pennstateind.com/store/DC3XX.html) but it is not cutting it for our 2 lasers. We cut wood and during the holiday season, both lasers are running 12+ hours a day for 2 months. I was thinking of getting 2 of the 2Hp models(https://www.pennstateind.com/store/DC250SEMB.html) so each machine has a separate blower. My concern is noise. Right now our blower is in another room, but at the new location, it will be out in the open. Currently, our blower is too loud so I can only imagine what 2 of the bigger blowers would be. I know I can build an enclosure, but it isn't ideal.
So my question is there a quieter blower that pulls around the same CFM/static pressure? I searched and it seems some are using a centrifugal or a squirrel cage fan. Are these quieter and if so are there any suggestions on brand/models?
