Plenum fans and dwdi fans are commonly found in these units but are not used exclusively.
Twin city ventilation fans.
Our broad range of technologies and expertise allow us to provide the most innovative and efficient air moving and ventilation products on the market.
With backward inclined backward curved backward inclined airfoil and forward curved wheel types centrifugal fans offer the flexibility to match the performance and application at the highest.
Since 1932 we have been supplying fans to industries covering most fortune 500 companies as well as small and medium sized companies that demand high quality products with a wide range of features.
Plenum fans are designed for general hvac applications where large volumes of clean air are required at low to moderate pressures.
Centrifugal fans are designed for general hvac and industrial applications where large volumes of clean air are required at low to moderate pressures.
Backward inclined airfoil wheels provide high efficiency performance and sound characteristics needed for the most stringent hvac applications.
They are available in direct and belt driven models with aluminum or steel propellers.
To accommodate the various applications these units are used for twin city fan offers the most diverse and efficient fans in the industry to meet the need of any air handling unit.
Fixed or adjustable pitch models are offered to meet a variety of application requirements.
The tfe employs a specially designed non overloading airfoil wheel.
In a tubular centrifugal fan the air turns 90 after leaving the wheel.
Twin city fan blower s unique wheel design with open back plate patent 5 171 128 allows this turn to be made with a minimum of turbulence loss.
Energy consumption and noise are often important considerations when selecting a fan for an ahu.
