Keep Your Epilog Running Without a Roof Vent

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.

Challenge: Venting through the foundation was not an option, and anodized-aluminum and acrylic jobs were saturating a small hobby filter every few weeks.

Outcome: The FS400's larger carbon mass extended replacement intervals several-fold at the same duty cycle, and the HEPA H14 stage keeps particulate out of the home's shared air. The household upstairs no longer notices when production is running.
