General features

Amongst the primary features of the centrifugal blowers with forward curved blades there is the high power density, which means a high pressure of air flow produced within a confined space. These blowers are suited to applications where a large air volume is to be moved within a small space.

The noise generated by these units is relatively low.

They can be used both as exhaust fans or as blowers.

The efficiency in the working point can be maximized, but when the working point approaches the free air point, the input power can increase considerably.

The housing of the single suction blowers is open only on one side. The main features of this range of products by Trial are high efficiency, low noise, high static pressure, rugged design and reduced size.

The motor types applied on this blower include: shaded pole, external rotor PSC or brushless.

Applications

• Fans
• Boilers and burners
• Printing and offset machines
• Industrial machinery
• Fume or vapour extractors
