Annexair
EC-Spider Fans
Next Generation Efficiency
Designed to maximize efficiency and minimize noise levels
Annexair’s fan incorporates the advantages of EC-PM motor technology and a super-efficient “Diffuser Wheel” with airfoil blade geometry to bring a new level of performance.
Features
•
Each wheel size can perform up to 10” TSP
•
Motor sizes range from 1 kW up to 15 kW (1.35 hp to 20 hp)
•
Internal motor shaft isolation prevents voltage induced bearing damage
•
Engineered with non-obstructive air intake
•
Molded edge on each back plate for increased rigidity and strength
•
100% epoxy coated fan ideal for corrosive environments
•
Airfoil blade geometry provides lower sound levels (dB)
•
Meets AMCA #204-05 for balance and vibration levels; Category BV-3
•
Lifetime maintenance-free motor bearing, no lubrication required
•
Box-free design, less metal parts means less reverberation
•
Piezometer tap ready for optional airflow measurement
•
Robotic welded Aluminium diffuser wheel construction
•
N+1 fan redundancy (optional)
The EC-Spider has been carefully designed and tested using the latest computer modeling, resulting in an outstandingly rigid assembly. Manufactured to extremely tight and precise tolerances, the EC-Spider provides improved overall fan performance.
