Compact Size-TD Fans require minimum space
The S&P TD-MIXVENT & TD-SILENT series of in-line duct fans have been specially designed to
maximize the airow performance with minimal noise levels within the smallest and most compact of
housing sizes. This makes the TD-MIXVENT & TD-SILENT series the ultimate solution for small to
medium sized ventilation installations which require a high airow to pressure ratio and occupy only
the minimum space possible. Example: false ceiling voids, cabinets and many other limited space
environments.
Easy to Install...t and forget!
All the models in the TD-MIXVENT & TD-SILENT range
have been designed with the professional contractor/
engineer in mind. All models include a “removable body”
feature that enables the motor-impeller assembly to be
completely removed or replaced without the need to
interfere with the attached ducting.
Multitude of features-high specication
All models within the TD-MIXVENT & TD-SILENT range incorporate a powerful mixed ow impeller
and internal air vanes located at the discharge end of the fan housing. This impeller and guide vane
combination provides a smooth laminar air ow which in turn minimizes turbulence and noise, and
generates an excellent air ow to pressure performance ratio.
Description
All of the TD-fans include the combination of a powerful motor, factory installed, to a mixed ow im-
peller. This motor and impeller combination enables the TD-fans to deliver high airow performances
with minimum noise generation against high static pressures typically found in ducted ventilation
systems. The unique design of the support brackets, allows the motor and impeller assembly to be
tted or removed without dismantling the adjacent ducting and therefore, facilitating any installation
or maintenance. The internal aerodynamic design of the TD-MIXVENT & TD-SILENT fans enable the
units to generate large air volumes and pressures with the minimum of in-duct or radiated noise. The
TD-fans offer the ideal in-line duct fan solution for a wide range of HVAC ventilation applications.
