Airfoil profile P4Z is commonly used type for supply/exhaust ventilation system. Blade made of aluminum alloy can be used for fireproof ventilation equipment. Impeller made of explosion proof material can be used for oil, gas and coal equipment.
Impeller diameters range from 250mm to 900mm with pitch angles from 25° To 50° . P4Z blade is mounted by means of a common blade root deign. The blades are fixed in the hub by means of a steel pin, ensuring a preset blade angle that cannot move or change under load.
Impeller diameters range from 310mm to 1100mm with pitch angles from 25°to 50°, the P5Z is geometrically scaled-up versions of the P4Z blade mounted by means of a common blade root deign. The blades are fixed in the hub by means of a steel pin, ensuring a preset blade angle that cannot move or change under load.
