These large AC powered axial fans are purpose-built for the rigors of the marine industry - not adapted from some other application. They are typically custom configured for your motor hp and certification, flow rate, and voltage requirements. Please call 800-426-6930 for details.
High efficiency, three-phase, direct-drive motors and high efficiency fan blades provide long, continuous-duty service life. Delta T 3-phase fan motors up to 15 horsepower use an aluminum frame and multi-point "spider" or "pad" mounting for corrosion resistance, light weight and enhanced air flow characteristics. 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. Standard motor sizes from 1/4 hp (0.19 kW) to 30 hp (23.4 kW) are available.
Corrosion resistant aluminum hubs are secured directly to the motor shaft using multiple locking methods for enhanced safety and reliability. Fan blades are non-corroding polypropylene composite and are pitch adjustable to allow for a wide range of flows and duties. No balancing required. 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 before leaving the factory. 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.
Flanged housings of welded marine grade aluminum provide light weight and excellent corrosion resistance. 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.
The installation of an optional intake Fan Guard to keep debris and foreign matter from entering the fan is highly recommended; see Accessory Products, below.
