Design & Construction
Axial Ventilation Fans produced by Delta T Systems are specifically designed and built for the rigors of the marine environment not adapted from other industries. Flanged housings of welded marine grade aluminum provide lightweight and excellent corrosion resistance. Aluminum housings are provided “mill finish” without paint, or optional powder coated in any color. Major assembly hardware is corrosion resistant stainless steel for long life. An external junction box mounted on the housing exterior is provided for electrical connections(Three-phase only).
Fan Hubs & Blades
Corrosion resistant aluminum hubs are secured directly to the motor shaft using multiple locking methods for enhanced safety and reliability. Fan blades are non-corrosive fiber-reinforced polypropylene composite and are pitch adjustable to allow for a wide range of flows and duties. The high performance airfoil blade shape provides for exceptional flow characteristics and low sound levels. All fans are tested in accordance with AMCA Standard 210. Axial Ventilation Fans have a non-overloading characteristic; the peak power input occurs within the range of normal operating pressures and is always exceeded by the motor rating.
Premium efficiency three phase and single phase direct drive motors are utilized to provide quiet continuous duty service. Available with CE Classification, 50 or 60 HZ, and optional I-EEE-45 Certification, these motors are designed for worldwide applications and can be provided in nearly any voltage configuration.
