Specifications
Premium AC Axial Fans
Design & Construction — Axial Ventilation Fans
produced by Delta “T” Systems are specically
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. 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.
Motors — High efciency 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, lighter weight and enhanced air
ow characteristics. Available with “CE” Classication,
50 or 60 HZ, and optional I-EEE-45 Certication, these
motors are designed for worldwide applications and
can be provided in nearly any voltage conguration.
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
reliability. Fan blades are non-corrosive polypropylene
composite and are pitch adjustable to allow for a wide
range of ows 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 nish”
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. For
larger vessels, axial marine grade fans are available up
to 106” (2690 mm) in diameter with ow rate to 600,000
CFM.
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 congured to
your exacting specications.
Custom Sizes — Can’t source a fan in time or need a
drop-in replacement for an existing fan? Need a larger
ow 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.
Fan Guards
Delta “T” Systems’ fan guards are available in all standard sizes. The welded steel
construction is plastic dipped for completely sealed protection from the elements.
Fan guards are a highly recommended option on Delta “T” Systems’ high-output
axial fans in order to prevent debris and other foreign matter from entering the fan.
