IBF EC

IBF fans are used in various mechanical ventilation systems. They combine advantages of axial fans' air flow direction with those of radial fans' stable compression, low noise level and high efficiency.
 

Application

IBF fans are used in various mechanical ventilation systems. They combine advantages of axial fans' air flow direction with those of radial fans' stable compression, low noise level and high efficiency. By using modern, high-performance electronically commutated (EC) drives, these fans are characterized by low energy consumption. Examples of application include supply and exhaust systems in apartments, offices, shops, bars, coffee houses and restaurants.

Construction

Duct fans are designed for mounting in any position within rectangular ventilation ducts. Housing, welded from galvanized steel sheet with an inspection flap for an easy access to the impeller and the motor without dismantling the installation. The housing is provided with 20 mm mounting flanges both at the inlet and outlet side. A separate junction box (single-phase models) facilitates connection to a power supply line, a junction box integrated with the motor in three-phase models.

The impeller, provided with backward-tilted blades, is designed to transport maximum volume of air at a high static pressure whilst producing a minimal level of noise. Depending on the size of the fan, the impeller is made of aluminum sheet (280, 315 i 355S models) or plastic (models from 355T to 560).

Electric motor

Highly efficient motor with integrated EC technology, which thanks to reduced power demand, minimizes operating costs and CO2 emissions. The fan motor is equipped with a 0-10VDC control input that allows variable rotation speed control. Insulation class - F Degree of protection - IP54. Power supply - AC 380 ... 480V 50Hz or 277V single-phase 200 ...277V 50Hz (depending on fan model).
