Bigass Fans work great in very large spaces like warehouses. I noticed they installed them in some airports too, like O’hare. High volume, low velocity.
But for bike trainers, treadmills, etc, the Laskos are the way to go. No comparison. If you’re itching to spend money, get the Wahoo fan. Those are sweet. Or go all out and install a mini split and make your basement ice cold.
