HAVACO ICS-EC Ultra-Quiet EC Fans 150–250 mm
Series Overview
The HAVACO ICS-EC series comprises ultra-quiet, high-performance in-line fans with EC motors. The key feature of this series is the 45mm noise-absorbing foam inside the housing, which ensures exceptionally low operating noise levels.
The housing is manufactured from powder-coated steel sheet. The design allows for ceiling mounting, making these fans the ideal choice for installations where acoustic comfort is critical.
Key Features
- Ultra-Quiet Operation: Thanks to thick sound-absorbing material, noise levels are just 41–48 dB — quieter than normal conversation.
- EC Motor: Electronically commutated motor with automatic thermal protection. The unit resets automatically in case of overheating. Protection class IP44, insulation class B.
- Control: Smooth speed regulation across the full range (0–100%) via 0-10V analogue signal. High efficiency maintained at all operating speeds.
- High Pressure: Powerful output (up to 805 Pa) enables use in systems with high duct resistance.
- Application: Perfect for apartments, offices, shops, hotels, and healthcare facilities where low noise levels are essential.
