Ventex offers a complete line of centrifugal fans for commercial and industrial applications in heating, ventilation, and air conditioning.
Fans are fluid or pneumatic machines designed to generate air currents, meaning they move air for various uses such as ventilating living environments, cooling objects or machines, and moving gases through a duct system. That’s why at Ventex, we focus on making fans with the latest technology and design, using high-quality materials and finishes.
In the commercial market, centrifugal fans provide supply, exhaust, and return air in schools, shops, and large office buildings. In industrial applications, Ventex centrifugal products enable the extraction of vapors and combustion air, transport shredded paper or wood chips, and supply filtered air in hospitals and clean rooms as needed.
Centrifugal fans are often preferred when it comes to pushing air through duct systems. As fluid transport devices, centrifugal fans are primarily used to produce gas flows from one point to another. While sometimes the gas conduit is essential, in many cases, the gas only acts as a means of transporting heat, moisture, or solid materials such as ash, dust, or waste. One common use of centrifugal fans is for ventilating fluid fuel heating boilers and propelling fuel mixtures in the industry.
Centrifugal fans intake air in the same direction as their axis of rotation, but they centrifugally accelerate it against an enclosing housing and expel it through an outlet at a 90° angle to the rotation axis. In short, centrifugal fans are those in which the airflow changes direction at a 90° angle between the inlet and outlet.
The most common materials and finishes for centrifugal fans are:
- PE (Polyethylene)
- Coating with epoxy paints or with resins and fiberglass
- Stainless steel
- Aluminum (spark-resistant)
Types of blades for centrifugal fans include:
E – Backward-curved blades
O – Backward-inclined blades
AIR WITH LOW DUST (2%)
U – Radial straight blades
