Features
- Aerodynamic shaped cowl for smoother air flow, reducedturbulence and increased fan performance
- Advanced mixed-flow impeller design provides high air flowwith low noise levels
- Lightweight design with aluminium housing for easy handlingand installation
- Smaller exhaust opening than traditional kitchen fansincreases discharge velocity and reduces exposure to rain
- Large drainage holes around base to prevent water build-up
- Supplied with matching flange for quick installation to suitstandard round Spiro duct
- Precisely matched motor, impeller and components to ensurequiet operation across all fan speeds
- 4-wire connection to junction box on all single phase units
- Can be used with smaller duct sizes as the fan can handlehigh pressure levels
