KSU & KSBF

Product catalog summary

Overview: The KSU and KSBF series are axial fans designed for wood drying kilns, available in diameters from Ø500 to Ø1000 mm. They feature reversible impellers for bi-directional airflow, suitable for environments requiring air direction changes by motor rotation. These fans operate efficiently in temperatures ranging from −20 to +105˚C and are also applicable in drying herbs, tobacco, fruits, vegetables, pasta, and animal feed.

Key Features:

High efficiency with short inlet and outlet housing.
100% reversible airflow capability.
Corrosion resistance and high-quality motor components.
Optimized housing shape for maximum airflow.

Electric Motor Specifications:

Asynchronous 3-phase motor with supply voltages of 3~ 230/400V; 400/690V.
Insulation class F or H and ingress protection IP 55.
Optional features include higher efficiency class (IE 4), different supply voltages, and enhanced ingress protection (IP 56, IP 66).

Optional Configurations:

Fan diameters from Ø280 to Ø2150 mm.
Operating temperatures from −30 to +120°C.
Explosion-proof options for hazardous zones.
Stainless steel casing and additional powder coating available.

Technical Data:

Standard diameters: Ø500 – Ø1000 mm with reversible impellers.
Air volume range: 5000 – 46800 m3/h.
Motor outputs: 0.55 – 5.5 kW with speed control via frequency converter.
Die-cast aluminum blades and hubs, maintenance-free bearings.

Dimensions and Performance: Detailed dimensions and performance metrics are provided for each fan type, including motor output, revolution speed, air volume, pressure, and mass. KSBF fans have larger pitch diameters on the connection flange compared to KSU fans.

Axial fans KSU and KSBF Ø500 ÷ Ø1000 mm designed for wood drying kilns Axial fans KSU and KSBF are produced in diameters from Ø500 to Ø1000 mm. As standard they are equipped with reversible (bi-directional) impellers. They have been designed to operate in wood drying kilns and other installations where it is required to change the direction of air flow by changing the direction of electric motor rotation. KSU and KSBF fans are adapted to operate in temperatures from −20 to +105˚C. They are equipped with special impellers based on cup-shaped blades, thanks to which they achieve maximum air flows...

Airflow curves PLHNETFRl ' KSBF fans differ from KSU fans in that they have larger pitch diameters of holes on the connection flange. The flow parameters presented in this brochure have been determined for the air density of p= 1.2 kg /m3 and are indicative data showing the general performance and pressure ranges of KSU and KSBF fans. The dimensions of the products provided are not binding and constitute general information. The manufacturer reserves the right to change, correct and/or improve the information and products presented in this brochure.
