With its mixed flow impeller, the ISO-MIX EC 250 fan combines the advantages of both axial and centrifugal fans, ensuring greater efficiency and quieter operation, even in larger systems that require high ventilation capacity.

This technology allows for higher pressure capabilities and more consistent airflow, even in systems with high resistance typical of larger buildings. Additionally, the mixed flow design reduces energy consumption, leading to lower operational costs while maintaining optimal performance in various industrial and commercial applications.

Maximum Noise Reduction: The ISO-MIX EC 250 fan is designed for ultra-quiet operation, making it ideal for noise-sensitive environments, particularly in larger settings. The fan’s casing is acoustically lined and packed with sound-absorbing mineral wool, effectively reducing noise from the air inlet, outlet, and breakout points.

Perforations along the inside of the casing further reduce both high and low octave sound, significantly lowering overall noise levels and decreasing decibel output. Inside the casing, special air straightening features minimise airflow noise, ensuring a peaceful environment without compromising on efficiency, even in high-demand settings such as commercial offices, industrial sites, and large residential complexes.

Versatile Sizing: The ISO-MIX EC 250 fan is designed to accommodate a variety of airflow requirements, with a capacity of 1500 m³/hour. The fan is carefully matched to deliver optimal performance across key parameters, including airflow rate, noise level, specific fan power (SFP), and Pascal (Pa) static pressure, particularly in larger applications where high capacity is required.

This ensures that the fan provides the perfect balance of efficiency and performance for different applications, whether it's for large-scale HVAC systems, extensive air circulation networks, or industrial ventilation ducts. With this duct diameter, you can select the ideal fit for your specific ventilation needs, ensuring efficient operation across various system designs, particularly in larger buildings.

Whether you're managing a large residential setup, a commercial building, or an industrial application, the ISO-MIX EC 250 fan delivers the ideal balance of airflow, quiet operation, and energy efficiency, all powered by the advanced EC motor technology, contributing to sustainable energy usage and reduced carbon footprint in large-scale applications.

Balancing Energy Efficiency and Acoustic Comfort

The Importance of Relevant Sound Data in Ventilation Systems

When selecting an energy-efficient ventilation system for larger applications, it’s crucial to consider not only airflow and power consumption but also the system's noise levels, as indicated by sound spectrum data. This data provides detailed insights into the noise generated by the system across various frequency bands at different points, such as the inlet, outlet, and external environment. Understanding these levels ensures the system not only meets ventilation requirements but also maintains a comfortable acoustic environment, which is especially important in large-scale settings such as commercial buildings, industrial facilities, and educational institutions where noise control is paramount.

Energy-efficient systems, particularly those using electronically commutated (EC) motors like the ISO-MIX EC 250 series, are designed to deliver high performance with minimal energy use. However, noise levels can vary significantly between systems, impacting the comfort and functionality of the spaces they serve, especially in larger applications. By carefully analysing sound spectrum data, you can select a system that minimises disruptive noise while still delivering the required airflow, effectively balancing energy efficiency with acoustic comfort in larger environments.

In practice, this involves reviewing sound power levels across different frequency bands to identify potential noise concerns and planning the system's installation accordingly. A well-chosen system, informed by sound spectrum data, ensures that the advantages of energy efficiency are not undermined by unwanted noise, resulting in a more pleasant and productive environment for all, particularly in larger settings.

Optimising Ventilation Design: The Role of Low Specific Fan Power in Achieving SAP Compliance

When designing ventilation systems for larger buildings, one of the critical factors to consider is Specific Fan Power (SFP), which measures the energy efficiency of a fan system relative to the airflow it generates. Lower SFP values are essential for ensuring that ventilation systems consume minimal energy while delivering adequate airflow. This consideration is especially crucial within the UK's regulatory environment, where compliance with the Standard Assessment Procedure (SAP) and Part L of the Building Regulations is mandatory. SAP, the methodology used to assess and compare the energy performance of dwellings, places significant emphasis on energy-efficient ventilation systems to minimise energy use and carbon emissions. The Chartered Institution of Building Services Engineers (CIBSE) also underscores the importance of low SFP in its guidelines, recognising its role in reducing a building's overall energy consumption and carbon footprint. By prioritising low SFP in ventilation design, architects and engineers can meet these stringent regulations, ensuring that their projects align with the broader goal of creating energy-efficient, sustainable buildings, particularly in larger applications.

The Blauberg ISO-MIX EC 250 series of in-line extractor fans perfectly aligns with the energy efficiency objectives set out in SAP and Part L of the Building Regulations. With the ISO-MIX EC 250 boasting an exceptionally low SFP of 0.47 W/(l/s), this fan demonstrates how advanced ventilation solutions can support SAP compliance by minimising energy consumption. The chart below illustrates the performance of the ISO-MIX EC 250 model, highlighting its suitability for projects where low SFP is critical. This fan delivers high airflow (up to 417 l/s) while maintaining low noise levels and achieving the low SFP values essential for both SAP and Part L compliance. By integrating this high-performance, energy-efficient fan, building professionals can ensure that their projects not only meet regulatory standards but also contribute to the development of sustainable, comfortable, and compliant indoor environments, particularly in larger buildings.
