When you are choosing a centrifugal blower, the first question is whether your priority is broad extraction or a concentrated, close-range boost. The 300W Centrifugal Blower Fume Industrial Extractor Fan and the Centrifugal Blower Fan 120W for Wood Stove, Boiler take opposite approaches. The 300W model is built for fume extraction; the 120W model is a compact fan for stoves and boilers. One is built for clearing large spaces; the other is built for concentrated blows.
Quick verdict
Pick the 300W Centrifugal Blower Fume Extractor Fan when you need to clear smoke, dust, or vapors from an enclosed space; it handles the big extraction jobs. Pick the 120W Centrifugal Blower Fan when you need a compact boost for a wood stove or boiler; it fits tight spaces and simpler setups.

Product notes
300W Centrifugal Blower Fume Extractor Fan
If you are extracting smoke, dust, or vapors from a hood, cabinet, or enclosed area, the 300W unit is built for that job. It moves 2300 m³/h through a 250mm exhaust port, which makes it a volume-focused machine. It also runs at a low 40 decibels, so it can operate near a workspace without shouting. The polypropylene body resists corrosion, and the 7kg weight shows the kind of material that goes into it. The catch is price and portability: it costs USD 184.23, and it is not something you want to move around constantly. If you only need small-scale spot ventilation, the 300W capacity is more than the job calls for, and the larger footprint takes up space.
Centrifugal Blower Fan 120W for Wood Stove, Boiler
For a wood stove or boiler, this 120W blower is the compact option. It costs USD 58.99, weighs only 2.5kg, and produces a static pressure of 350 Pa, which is actually higher than the 300W model. That pressure helps push air through a stove pipe or tight openings. The carbon steel body and pure copper motor are notable construction details, and the 2600rpm speed creates strong wind from a relatively small unit. The limitation is noise and volume. It runs at 72 decibels, so it is not a quiet fan, and its 5.5 m³/min airflow is far below the 300W model's output. For large-volume fume extraction, this blower would need to run much longer and still not match the extractor's capacity.
Final choice by use case
For fume extraction, chemical cabinets, and workshop ventilation, choose the 300W Centrifugal Blower Fume Extractor Fan. For wood stove or boiler air boosting and portable setups, choose the 120W Centrifugal Blower Fan.
