MODEL CTB
TUBULAR CENTRIFUGAL INLINE BELT DRIVEN FAN
MODEL OVERVIEW
S&P’s inline tubular centrifugal line offers one of the widest range of sizes, horsepower and performance
in the industry. Models CTB are high capacity belt drive tubular centrifugal fans rated from 300 to 20,000
CFM, with static pressure capability up to 2-1/2”. Designed for commercial and industrial in-line applications
that demand quiet, efcient and reliable air movement, they are used to exhaust air from or supply air
to such typical commercial and industrial applications as general building ventilation, enclosed garages,
paint spray booths, heat and smoke ventilation systems, restaurant and kitchen exhaust ventilation,
historical buildings with limited roof space and restrictive duct lengths, and other applications where air
is moved through a duct system against moderate static pressure. The CTBRHUL is specically suited
for restaurant exhaust where roof space is limited, sidewall mounted fans are prohibited or duct lengths
are restricted. The CTBRHUL is also perfect in areas where extreme weather and outside air temperature
is a concern when maintenance on the fan is needed.
The centrifugal wheel is designed to provide higher efciencies and lower sound levels than propeller
type fans when used in medium pressure ducted systems. Tubular centrifugal fans can be mounted in
any position from horizontal to vertical providing for installations in the smallest possible space.
