(3). Main Features
Poultry fan instruction:
1. Huge airflow, Low noise, high efficiency.Good looking, the surface smoothness & gloss without rough edges.
2. Shutters be use counterweight open-close system.Easy to maintenance.
3. Fan housing: Strength galvanized steel.
Shutters: Stainless steel, good seal performance, prevent rain come into the fan and easy to remove and maintenance.
4. Fan Propeller: 6pcs blades of propeller made from CNC punch.
Rational angles of the blades to supply huge airflow and low noise.Fan blades with strength galvanized steel
5. Motor: Die casting aluminum body & Die casting iron body for options, good for heat transfer and l Low noise. With over-load protection inside.
6. Belt Pulley:Be made by strength die casting aluminum with once-forming press. Smooth surface of the groove to supply low noise and huge airflow, and extend the working life of the belt.
9. V-Belt: be use USA “GATES” belt to supply performance of high strength & good ductile.
(4). Centrifugal butterfly cone fan
Butterfly fan is develop from standard 50” cone fan, with more powerful ventilation speed and higher negative pressure in the poultry or livestock house.
