BIFURCATED FANS
Take a look at the ranges we offer
Bifurcated fans are designed to keep the motor out of the airstream preventing it from being damaged or clogged by the pollutants being ventilated.
Bifurcated Axial Flow Fans
Bifurcated Axial fans are used in challenging environments where a normal axial fan would encounter significant problems- typically in high ambient temperatures (higher than the motor is rated for), corrosive or heavily polluted atmospheres.
WHAT IS A BIFURCATED FAN?
Bifurcated fans - also known as BIF Fans or Bifs - are an inline axial fan designed with a split airway, where the motor is mounted inside a tunnel or enclosure so that it is shielded from the detrimental air conditions. This motor shielding encloses the motor, separating it from the air that is flowing through the fan. The bifurcated design protects the motor from hot, abrasive or corrosive air, prolonging its life and reducing maintenance needs.
BIFURCATED AXIAL FAN APPLICATIONS
BIFs are used to exhaust a wide variety of hot gases, paint fumes, smoke, steam and suspended dust or fibres. Ideal for medium to high volume applications with low pressure development. However, as this fan variant uses a bifurcated casing design, this will reduce fan efficiency, meaning that in some cases a larger unit might be needed to achieve the required air movement.
- They are often used in industrial kitchens such as food factories, for efficient and safe extraction of hot air and cooking fumes. They are also suitable for use in commercial kitchens where greasy steam can build up.
- In Industrial Spray Booths, particularly those dealing with corrosive materials, bifurcated fans are essential for maintaining a safe working environment. If the spray booth uses cellulose paint, there will also be the need for an ATEX-rated bifurcated fan depending on Zone and Category.
- In heavy industrial settings their robust design makes them suitable for applications where air might contain small, abrasive particulates or corrosive elements such as cement works and paper mills.
