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 light weight and excellent corrosion resistance. Major assembly hardware is corrosion resistant stainless steel for long life. An extemal junction box mounted on the housing exterior is provided for electrical connections.
Motors — High efficiency three phase and single
phase direct drive motors are utilized to provide quiet
continuous duty service. Our motors 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 (.19 kW) to 30 HP
(23.4 kW) are available.
Fan Hubs & Blades — Corrosion resistant aluminum
hubs are secured directly to the motor shaft using
multiple locking methods for enhanced safety and 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.
Finish — Aluminum housings are provided “mill finish” without paint, or powder coated in any color.
Standard Sizes — Our premium series fans range in size from 12” (305 mm) ID to 60” (1524 mm) ID.
Standard Flows — Ranging from 875 CFM (42
m3/Min) to 100,000+ CFM (1642.4+ m3/Min), Delta
“T” Systems Axial Ventilation Fans can be configured to your exacting specifications.
Custom Sizes — Can’t source a fan in time or
need a drop in replacement for an existing fan?
Need a larger flow or diameter than the standard
sizes? Just provide us with your requirements and
housing dimensions and Delta “T” Systems will
build your fan using the same high quality marine
components as our premium series.
