Strip-mall awards shop runs a Fusion Pro with zero ductwork
Fusion Pro 32 (60 W CO2)
Challenge: The landlord would not permit exterior wall penetrations, but the Fusion Pro's exhaust requirement is far beyond what hobby-grade filter boxes deliver — acrylic odor was reaching neighboring tenants.
Outcome: Running the FS500 in recirculating mode held visible smoke clearance at the lens carriage even on full-sheet acrylic engraves. The deep carbon bed keeps the sales floor odor-neutral, and quarterly filter swaps take under ten minutes.
