In-line/Sidewall Duct Fans

TD-MIXVENT Model

TD-MIXVENT

In-line Mixed Flow Duct Fan

The TD-MIXVENT series is an in-line duct fan specially designed to maximize the airflow performance with minimal noise levels in a small, compact housing. This makes the TD-MIXVENT series the ultimate solution for small to medium sized ventilation installations which require a high airflow to pressure ratio and occupy minimum space (e.g., false ceiling voids, cabinets and many other limited space environments).

TD-SILENT Model

TD-SILENT

In-line Mixed Flow Duct Fan (Designed for Rigid Duct Applications)

The TD-SILENT fans are extremely quiet, low profile fans manufactured in the tough reinforced plastic material. Sound waves are directed through the perforated inner skin and absorbed by a layer of sound-absorbent insulation. These fans are fitted with rubber gaskets on the inlet and outlet to facilitate installation, absorb vibrations, and provide a virtually air-tight seal.

SWF-SIDEWALL Model

SWF-SIDEWALL

Sidewall Centrifugal Fan

The Sidewall Fan Series utilizes the same powerful high static motor found in the popular PV Series fans, yet the SWF series is encased in an exterior mounted housing. The outdoor rated exterior housing provides easy access from the outside of a building or dwelling. This makes the SWF a great solution for installations where attic space or easy indoor access is challenging and not suitable for traditional PV style in-line mounting. The SWF series of direct drive centrifugal ventilation fans consists of five model sizes ranging from 4-8". All models are designed for direct connection in-line with standard diameter round ducting. Airflow performance values range from 119 to 416 CFM.
