DESCRIPTION
The S&P CVTT with our standard features is the Quietest forward curved cabinet fan in its
category. The CVTT range of belt-drive double inlet centrifugal cabinet fans consists of 10
nominal product sizes with motor powers ranging from 0.18 up to 15.0kW. Airflow performances
range from 500 up to 42,000 m3/hr, with static pressures up to 600 mmWG. The CVTT series
can be supplied suitable for either horizontal (H) air discharge depending upon the requirements of
the installation. In addition to special order, the units can be supplied with circular inlet and
discharge duct connection flanges (rectangular supplied as standard). The CVTT range of fans
offer a very flexible supply or exhaust air ventilation solution to many applications, including the
ventilation of factory units, offices, restaurants and commercial kitchens.
