For compressors, blowers, and air treatment, the real decision starts with a simple question: do you need to move a lot of air, or do you need to push air through resistance? The 300W Centrifugal Blower Fume Industrial Extractor Fan and the 2.8Hp Industrial Air Blower sit at opposite ends of that question. One is built to pull a large volume of air out of a space; the other is built to maintain pressure inside a system. Your choice comes down to volume versus pressure.
Quick verdict
If your priority is exhausting fumes, smoke, or vapour through a wide duct, the 300W centrifugal extractor is the lower-cost option. It moves a lot of air but produces modest static pressure, so it suits low-resistance exhaust paths. The right pick depends on your duct length, pipe size, and whether the air has to carry anything. If your process needs to keep air moving against backpressure, the 2.8Hp regenerative blower is the one to specify. It delivers high pressure with a much smaller flow rate, which is a completely different kind of air moving capability.

Where each product wins
The 300W centrifugal extractor wins on airflow per dollar. It is the cheaper way to exchange a large volume of air through a wide exhaust port, and its polypropylene housing resists corrosion, which fits fume and chemical exhaust duty.
The 2.8Hp regenerative blower wins when the system pushes back. Its high pressure keeps air moving through narrow tubing, filters, and longer runs. It is also oil-free, which suits applications where clean, dry air matters.
Product notes
Centrifugal Blower Fume Industrial Extractor Fan
The LXFJ-250 is a centrifugal fan with a 1,450 rpm motor and an exhaust port diameter of 250 mm. It moves a large volume of air while drawing a modest amount of power, and its PP construction provides corrosion and wear resistance for fume, dust, smoke, and vapour exhaust. The noise level is low, making it a quiet option for workshop ventilation. The limiting factor is static pressure: it is enough for open ducting but not for long, narrow, or heavily filtered runs. If the exhaust path becomes restrictive, the air volume will drop noticeably. Keep this one for high-volume exhaust through a short, wide path.
2.8Hp Industrial Air Blower 220V-480V/3Ph
The GHBH 002 34 1R5 is a regenerative blower built for pressure and vacuum applications. It uses a three-phase motor to produce steady pressure at a moderate flow rate, and the 2-inch inlet and outlet make it easy to connect to industrial piping. The cast aluminum housing and oil-free, maintenance-free operation suit applications where you need stable pressure and clean air. The main drawback is flow: it will not clear a large open space quickly. It also requires a three-phase supply, which is a common industrial setup but not universal in smaller shops.
Final choice by use case
Choose the 300W Centrifugal Blower Fume Industrial Extractor Fan when you need to exhaust smoke, dust, or vapour through a wide, low-resistance duct and want the lower listed price. Choose the 2.8Hp Industrial Air Blower 220V-480V/3Ph when your application depends on maintaining high pressure through restrictive lines, filters, or process equipment.
