The Korfmann AL 17 - 25 is a robust two-stage axial fan designed for industrial applications, manufactured in 1997. This model features a double body construction with an overall length of approximately 4.4 meters (excluding silencers) and a fan diameter of 1,700 mm. It is powered by two electric motors, each delivering 250 kW, resulting in a combined motor power of 500 kW. The motors operate at 400 volts and a rotational speed of 1,000 RPM, providing a total volume flow rate of about 128 cubic meters per second (64 cubic meters per second per stage). The fan is capable of generating a static pressure of up to 3,000 Pascals for a single stage. The motors are equipped with IP 55 protection, ensuring a degree of protection against dust and water ingress.
The unit is painted yellow and shows visible signs of wear, including chipped paint and surface rust on multiple areas of the metal surfaces. The motor housings also display some black sealant or repair material around circular covers. The internal fan blades and motor assembly exhibit surface rust and dust accumulation, indicative of outdoor storage or previous use in demanding environments. An ABB-branded electrical component is mounted on the side of the unit, and the machine includes metal plates with electrical specifications and manufacturer information, which are weathered but mostly legible.
This Korfmann AL 17 - 25 fan is also available for sale as separate single units. It is suitable for buyers looking for a high-capacity axial fan with a significant flow rate and pressure capability, acknowledging the visible cosmetic wear and surface corrosion present on the equipment.
