300W Centrifugal Blower Fume Industrial Extractor Fan Dust Smoke Vapour Exhaust
If your workspace needs to pull fumes, smoke, or dust away from a chemical cabinet, fume hood, or lab bench, the first question isn't just how much air the fan moves-it's whether it has enough pressure to push that air through ducting and filters. The 300W Centrifugal Blower Fume Industrial Extractor Fan Dust Smoke Vapour Exhaust is built around exactly that challenge, and at USD 184.33 it sits in the practical range for a dedicated extraction unit.
#### Quick verdict
This is a purpose-built centrifugal exhaust fan for laboratory and chemical-cabinet setups. Its 2300 m³/h airflow and 260 Pa hydrostatic pressure give it the muscle for moderate duct runs, while the polypropylene body gives it anti-corrosion properties for the kinds of vapours that eat ordinary metal fans. Just be prepared to handle the wiring yourself-this unit relies on color-coded speed wires rather than a plug-and-play controller.
#### Who it suits
This blower makes sense for anyone who needs a fixed extraction point near a chemical cabinet, fume hood, or medicine cabinet. The 250 mm exhaust port matches ducting that can move serious air, and the low-noise design helps if you're working in a shared lab space. It also suits anyone comfortable with basic electrical wiring, since the three motor speeds are selected by connecting the red, blue, or black wire to the live line.
#### What stands out
The headline specs are airflow and static pressure. At 2300 m³/h, the airflow is substantial for a cabinet-scale exhaust, and the 260 Pa hydrostatic pressure helps it push against duct resistance. The polypropylene construction is a key detail: its anti-corrosion profile is what makes it a fit for chemical-cabinet and fume-hood ventilation. The three-speed wiring gives you flexibility-run it on low for quieter daily use or high for heavy fume clearance.
#### Meaningful trade-offs
The biggest trade-off is the wiring. The color code is straightforward: yellow zero line, red high-grade, blue mid-range, black low-grade, and a two-color yellow wire with a small iron sheet for grounding. That means you're doing a hardwired installation, not simply plugging in a cord. If you're not comfortable with mains wiring, you'll need someone who is. And to change speeds, you'll physically reconnect wires rather than flipping a switch.
#### Bottom line
If you have a chemical cabinet or fume hood and you're ready to do a proper hardwired installation, this 300W centrifugal blower gives you anti-corrosion PP construction, strong airflow, and enough static pressure for flexible ducting at USD 184.33. For a dedicated lab exhaust, it's a solid fit.
