Direction of Airflow Versatility of airflow direction of form 'B' or form 'A' Hison Axial Flow Fans Surface Coating Hot Dipped Galvanized to EN ISO 41:1999 which also comply to ASTM A123, A153 and BS 729. Blasted to SA 2-1/2 and coated with Hi-Built epoxy paint for marine environment and most industries applications. Special painting to user specification is available upon request. Impeller Adjustable Blades angles design to meet varied volume and pressure system requirements featuring the blade shank with tapered conical section. The tapered section fits into a conical slot in the hub, providing a taper lock fit. A bolt is cast into the blade, projecting into the hub and is secured on the inside by lock-washer and nut. Balancing Standard All fan impellers are statically and dynamically balanced to ISO 194-1973 (E) G:.3 standards. Motors All Fans shall be supplied with totally enclosed, high eff iciency motors of IP 55 degree of protection, foot-mounted Class F insulation, built to International Standard (IEC) Special motors such as Explosion Proof, 2 speeds, Class H or D.C. motors are available to suit each specific application. Accessories Separate upstream and downstream guide vanes Inlet/Outlet Silencers Mounting Feet Inlet Cones Matching Flange Mushroom Ventilators Control Damper Wire Guards Anti-Vibration Mountings * Fan silencers are recommended for sound level exceeding 8dBA at 3m distance.
