In-Line Duct Fans - ILT / ILB Series

ILT ILB Series

Features

The ILT/ILB range of centrifugal low pressure fans are suitable for many general ventilation applications where the fan is required to be installed within a rectangular ducted ventilation system or where the space for installation is limited. Due to the configuration for the design, the dimension of the fan section would be no greater than that of the proposed nominal ducting.
Typical installations would include:
- Commercial offices air extract/supply.
- Car park supply air.
- Restaurants.
The range comprises of eight nominal model sizes, covering 23 models in total. The range is available with single 230V 50Hz or three phase 230/400V 50Hz motors in 4,6 and 8 pole speeds.
Air volume performance ranges from 1,090 up to 10,235 m³/hr.
All models are suitable for mounting in any orientation and operation within ambient air temperatures between -40°C up to +70°C.

Casing
The fan casings are manufactured from heavy gauge galvanised sheet steel. All models incorporate an inspection cover that can be removed to access the motor/impeller assembly without having to remove the complete fan casing from the ducting.

Motor/Impeller
All models incorporate direct-drive low pressure forward curve centrifugal impellers. The impeller is factory matched to the motor and the complete assembly is dynamically balanced to ISO 1940 standards.

Motors
All motors incorporate asynchronous induction motors with squirrel cage rotor in die cast aluminium and are manufactured in accordance with IEC 34-1 standard. The following specifications apply;
- Single Phase 230V 50HZ
- Three Phase 230/400V 50 Hz
- IP55 protection
- Class F insulation
- Thermal Overload Protection
- Sealed for Life, ball bearing assemblies
- Remote mounting wiring outlet box. (800mm lead lenght)
