The sileo generation

Product catalog summary

Overview of the Sileo Range:
The Sileo range of fans is engineered for both power and silence, featuring a high-performance fan impeller that reduces noise by nearly 50% while maintaining or enhancing system performance and efficiency. The impellers are crafted from high-quality composite materials, providing high power density, corrosion resistance, and UV resistance. The backward-curved fan blades ensure optimal airflow with minimal noise emissions, meeting and exceeding ErP requirements.

Main Features:

High efficiency with advanced ventilation technology.
Extremely quiet operation due to optimized impeller airflow.
Significantly reduced rotation noise.
High power density and rugged, maintenance-free design.
Compliance with ErP specifications.

Technical Comparisons:
The document includes detailed technical data and comparisons between older fan models and the new Sileo models, highlighting improvements in power consumption, airflow, sound pressure levels, and overall performance. Key improvements include reduced power consumption, lower sound pressure levels, and increased airflow capacity across various models such as K 100 M, K 100 XL, K 125 M, and others.

Performance Data:
Graphs and tables illustrate the performance metrics of different fan models, including airflow rates (m³/s), power consumption (W), sound pressure levels (dB(A)), and rotational speeds (r.p.m.). These data points demonstrate the enhanced efficiency and quieter operation of the Sileo fans compared to their predecessors.

Technical Specifications:

Voltage and Frequency: All models operate at 230V and 50Hz.
Phase: Single-phase (~1) operation.
Power and Current: Power consumption ranges from 52W to 208W, with corresponding current ratings.
Max Airflow: Varies by model, with maximum values ranging from 0.098 m³/s to 0.351 m³/s.
R.P.M.: Revolutions per minute range from 2387 to 2633 depending on the model.
Temperature: Maximum air temperature for transport is 70°C, with speed control.
Sound Pressure Level: Measured at 3 meters, levels range from 38 dB(A) to 53 dB(A).
Weight: Models weigh between 2.1 kg and 5.5 kg.
Insulation and Enclosure Class: Insulation class B or F, with an enclosure class of IP 44.
Capacitor: Capacitor values range from 1.5 µF to 5 µF.

Performance Data:

Graphs illustrate the relationship between airflow (Q) in m³/s and pressure (P) in Pa, as well as power consumption (P) in watts.
Data is provided for different models, including KV sileo 125 M, 150 M, 160 M, 200 M, 250 M, and 315 M, among others.

Dimensions:

Dimensions are provided for each model, detailing measurements such as diameter (øA, øB), and lengths (C, D, E, F).

Accessories:

Electrical accessories include transformers, speed controllers, and sensors.
Mechanical accessories include duct heaters, filter cassettes, silencers, and back draft dampers.

| Fans of the sileo Generation Fans of the sileo generation Your advantages at a glance: •• The secret of the new sileo generation is the improved quiet-running high-performance fan impeller. The result: a reduction in sound of almost 50% at the same or even higher system performance and an increased level of efficiency compared to its predecessors. •• The impellers are manufactured of high quality composite material in a single piece without joints. This makes a high circumferential speed possible, so the fan has a high power density. The material is highly corrosion-resistant (e.g. salt water...
