When you're shopping in the compressors, blowers, and air treatment category, the decision often comes down to one question: where does the air need to go? Are you pulling fumes, dust, smoke, or vapour out of a workshop, or are you pushing warm air from a wood stove or boiler into a living space? The 300W Centrifugal Blower Fume Industrial Extractor Fan and the Centrifugal Blower Fan Industrial Fan Air Blower Fan 120w for Wood Stove, Boiler both use centrifugal impellers, but they are built for different jobs.
Quick verdict
The $125.24 difference between them is the key fork in the road. Both run on 110V/60Hz, so voltage should not be the deciding factor. If you need to clear fumes, dust, smoke, or vapour from a workshop, the 300W extractor is the stronger candidate. If you are moving heat from a stove or boiler and want to keep the purchase small, the 120W blower is the practical choice.

Product notes
300W Centrifugal Blower Fume Industrial Extractor Fan

The 300W extractor makes ducting easy with its 250mm exhaust port, and the PP polypropylene body resists corrosion and high temperatures. That combination makes it a natural fit for ventilation around chemical cabinets or industrial work areas. The main limitation is physical bulk: the packing size is 42 × 38 × 38 cm and the unit weighs 7 kg, so it suits a permanent installation more than a portable tool. It also draws 300W, which is more than double the smaller blower's power draw, so consider that if your outlet is already loaded. If you are setting up a dedicated extraction station, this is the one to build around.
Centrifugal Blower Fan Industrial Fan Air Blower Fan 120w for Wood Stove, Boiler

The 120W blower takes the opposite approach. It delivers a higher pressure rating (350 Pa versus the 300W model's 260 Pa), so it can push air through a smaller outlet with confidence. The compact carbon steel housing and pure copper motor make it a good fit for wood stove and boiler installations, and the IP54 protection rating adds reassurance for utility-area use. The trade-off is noise: at 72 dB(A) it is noticeably louder than the 40 dB extractor, so it is not the best choice for a quiet living space. It is a targeted air mover, not a whole-workshop ventilator.
