Fans - rectangular duct

Fans - rectangular duct

In the category of fans for four-sided ducts, there are mainly fans with the radial impeller construction. These rectangular fans are intended for more complex ventilation applications where higher pressure losses are expected to be overcome. Usually these are not silent fans, but our offer also includes fans with a sound-insulated housing that achieves acceptable noise parameters.

ILB / ILT

ILB / ILT

The ILB (230V) and ILT (400V) radial fans are designed for installation in four-sided ducts. They are designed to transport air without mechanical particles that could cause the impeller to become abrasive or unbalanced. Due to the IP protection and higher working temperature, the ILB/ILT fans are suitable for the ventilation of restaurants, hospitals, sports halls, warehouses and production areas where the low installation height of the fan is beneficial.

 

IRAB / IRAT

IRAB / IRAT

The IRAB N / IRAT N silent radial fans with sound insulation are suitable for areas such as restaurants, hospitals, sports and production halls, warehouses, etc. The IRAB N / IRAT N fans have a low installation height and a higher working temperature of up to 70 °C. The fan housing is acoustically insulated with a 50 mm layer of insulating material, made of galvanized sheet steel.

The housing is equipped with a service door on which the impeller motor is installed for easy cleaning and maintenance. The installation of the fan is possible in any position of the fan, with respect to inspection operations and opening of the inspection door, preferably vertically with the motor axis.

 

KT

KT

The KT fans are designed for a direct connection to rectangular duct. The KT fans are radial single inlet fans with forward curved blades and with an external rotor motor. For easier service and maintenance, the fans are equipped with a tilting impeller. The fan casing is made of galvanized steel sheet.

The KT fans can be installed in any position and are adapted for speed control by changing the voltage. The fan speed can be controlled by a 5-stage transformer or by a frequency converter with a sine filter. The motors are equipped with built-in thermal contacts running to the motor screw terminal, which must be connected to the corresponding thermal overload relay. The KE fans can be installed in any position.

 

RS/RS EC

RS/RS EC

The RS / RS EC radial duct fans are designed for direct connection to four-sided ducts. The RS / RS EC fans are single inlet radial fans with backward curved blades and an external rotor motor. For easier service and maintenance, the fans are equipped with a tiltable impeller. The fan housing is made of galvanized sheet steel. The transported air must be free of particles that could cause corrosion, motor fouling or impeller imbalance. The fans must not be directly exposed to weather. They can be installed in any position and are adapted for speed control by changing the voltage.

 

RSI / RSI EC

RSI / RSI EC

The RSI / RSI EC radial duct fans are designed for direct connection to four-sided ducts. The RSI / RSI EC fans are acoustically insulated, single inlet fans equipped with a radial impeller with backward curved blades and with an external rotor motor. The fan housing is made of galvanized sheet steel. The fan is thermally and acoustically insulated with a 50 mm layer of mineral wool, which is attached with perforated galvanized sheet steel. For easier service and maintenance, the fans are equipped with a tiltable cover. They can be installed in any position and are adapted for speed control by changing the voltage.
