SQ specifications

The Greenheck Fan SQ series represents an innovative line of high-performance fans designed to meet diverse ventilation and exhaust needs in commercial and industrial applications. Renowned for their reliability and efficiency, the SQ fans embody Greenheck's commitment to providing advanced air movement solutions that enhance indoor air quality and energy efficiency.

One of the standout features of the Greenheck Fan SQ series is its powerful centrifugal design, which maximizes airflow while minimizing energy consumption. The fans are engineered to deliver high static efficiency, making them ideal for systems that require substantial airflow against high resistive pressures. This capability ensures optimal performance in various settings, from large commercial kitchens to manufacturing facilities.

The SQ series incorporates several advanced technologies that set it apart from traditional fans. First, the fans utilize a direct drive system, eliminating the need for belts and pulleys. This design not only reduces maintenance needs but also enhances overall operational reliability. The fans also feature an integrated motor design that optimizes airflow patterns and reduces energy waste, contributing to lower operational costs.

In terms of construction, Greenheck SQ fans are built to withstand the rigors of demanding environments. The housing is constructed from sturdy, corrosion-resistant materials, ensuring longevity even in challenging conditions. Additionally, the fans are available in various sizes and configurations, allowing for custom solutions tailored to specific ventilation requirements.

The SQ series also incorporates advanced sound attenuating technologies, making them quieter than many conventional fans. This is particularly beneficial in environments where noise reduction is essential, such as school auditoriums, offices, and healthcare facilities.

Furthermore, the SQ fans are equipped with easily accessible inspection ports, facilitating routine maintenance and ensuring sustained performance over time. Greenheck also offers a range of options, including variable speed controls, which provide flexibility in managing airflow based on real-time demands.

In summary, the Greenheck Fan SQ series stands out as a leader in efficient, reliable ventilation solutions. Its advanced design features, energy-saving technologies, and robust construction make it an ideal choice for a variety of commercial and industrial applications, helping users achieve optimal performance while prioritizing energy efficiency and indoor air quality.
