When you need to move air in an industrial or lab setting, the first fork in the road is whether you want high volume or high pressure. The 300W Centrifugal Blower Fume Industrial Extractor Fan is built to pull large amounts of air out of enclosed spaces. The 2.8Hp Industrial air blower is a regenerative blower designed to deliver steady pressure and vacuum. This head-to-head compares their prices, airflow, and real-world fit so you can choose the one that matches your job rather than overbuying on the wrong specification.
Quick verdict
The $184.33 300W Centrifugal Blower is the right pick when your job is fume, smoke, dust, or vapor exhaust from a cabinet, hood, or room. It moves 2,300 m³/h of air and carries an Energy Star A+ rating. The $779 2.8Hp Industrial air blower is the right pick when you need concentrated pressure or vacuum-84" H2O pressure and 88" H2O vacuum-for conveying, aeration, or holding work. In short: choose the 300W for airflow, choose the 2.8Hp for pressure.

| Best fit | Fume hoods and ventilation | Pressure and vacuum applications |
Where each product wins
- 300W Centrifugal Blower wins on air volume and lower upfront cost. It has the higher airflow rating of the pair, so it suits exhausting fumes, smoke, and vapors from enclosed areas.
- 2.8Hp Industrial air blower wins on pressure, vacuum, and industrial build. Its regenerative design and three-phase motor suit pneumatic conveying, aeration, and vacuum hold-down tasks.
Product notes
300W Centrifugal Blower Fume Industrial Extractor Fan Dust Smoke Vapour Exhaust
The 300W centrifugal extractor gives you a lot of air movement for a modest investment. It has the higher airflow of the pair, a corrosion-resistant PP (polypropylene) body, and a 250mm exhaust port, making it a natural fit for chemical cabinets, fume hoods, and lab ventilation. The trade-off is pressure: with only 260 Pa hydrostatic pressure, it is not built to push air through narrow ducting or maintain vacuum. If the job is removing fumes, smoke, dust, or vapors from an enclosed space, this is the more practical choice.
2.8Hp Industrial air blower 220V-480V/3Ph. 150CFM, 84\"H2O press GHBH 002 34 1R5
The Goorui-USA 2.8Hp regenerative blower is the pressure specialist. It moves less air per hour than the 300W extractor, but its three-phase 220V-480V motor, cast aluminum alloy housing, and IP55 enclosure are built for steady pressure and vacuum work. The package also includes CE/ISO9001/RoHS certifications and a one-year warranty. The downside is that it costs substantially more and delivers a much lower airflow rate, so it makes sense only when your process actually needs the higher pressure and vacuum capability rather than simple ventilation.
Final choice by use case
- For fume, smoke, dust, or vapor exhaust from a cabinet or room: choose the 300W Centrifugal Blower. Its high airflow and ventilation-focused design make it the practical workhorse.
- For pneumatic conveying, aeration, or vacuum applications: choose the 2.8Hp Industrial air blower. Its pressure output, vacuum capability, and industrial build justify the higher price.
