Thermador ventilation systems
Thermador vent hoods range from 600 to 1,000+ CFM blower capacity in wall-mount, island, under-cabinet, and built-in configurations. The Professional series features commercial-grade stainless steel construction with dishwasher-safe baffle filters. Many models include auto-on heat sensors that activate ventilation when cooking heat is detected, and delay-off timers that continue extraction after cooking ends.
Downdraft ventilation — integrated into select cooktops — uses a retractable design that rises from the counter when needed. This motorized lift system, combined with the blower motor, creates additional service points not present in standard hood installations.
What a Thermador vent hood service visit includes
The technician tests blower motor at all speeds, checks CFM output, inspects filters and ductwork, verifies damper operation, and tests lighting and controls. For downdraft units, the lift mechanism is inspected and lubricated. Genuine OEM parts, 30-day warranty.

Frequently asked questions about Thermador vent hoods
How much CFM do I need?
Divide your cooktop’s total BTU output by 100. A 36″ gas cooktop at 60,000 BTU needs at least 600 CFM. For induction, 400-600 CFM is typically sufficient since induction produces less heat and steam.
What’s a remote blower?
Instead of the blower motor inside the hood, a remote blower mounts in the attic or on an exterior wall. This dramatically reduces kitchen noise. The hood controls communicate with the remote motor via a dedicated wire.
How do I clean baffle filters?
Run them through the dishwasher on the bottom rack with baffles facing down. Monthly for typical cooking, weekly for heavy cooking. They’re made of stainless steel and designed for thousands of wash cycles.
Do I need a charcoal filter?
Only for recirculating installations (no duct to outside). Ducted installations use baffle filters only. If your hood exhausts to the outside through ductwork, you don’t need charcoal filters.
