Key Features
400 mm Impeller
The 400 mm fan diameter supports high-volume air movement in condenser, evaporator and ventilation applications where a large swept area is required.
Dual-Speed 50/60 Hz Operation
Published data shows 1450 rpm at 50 Hz and 1690 rpm at 60 Hz, with corresponding power and pressure variations for different supply frequencies.
IP44 Protection
Rated IP44 for protection against solid objects larger than 1 mm and water splashes, appropriate for many outdoor and semi-exposed HVAC installations.
Wide Temperature Range
Published operating temperature range of -40°C to +70°C supports use in refrigeration, condenser and industrial ventilation environments.
Applications
- Condenser and evaporator fan assemblies
- HVAC air-cooled equipment
- Refrigeration systems
