The next generation

Third generation ModuVent™ technology lets you choose between a soundproof steel cover or filtered multi-fan ventilation setup in the top panel
”The flexibility is a real boon, and is enhanced by Fractal's attention to detail. A hinged tempered-glass panel works really well, the top ModuVent is better than ever, the front door is reversible, the top, front and bottom are outfitted with easy access dust filters and there's sound-dampening material throughout.”
