DESIGN USE
The centrifugal fans series VL are designed and manufactured to extract air from any kind of
industrial environment.
Their use is necessary where an exhausting system is required, particularly when corrosive
or aggressive substances are present, because the construction materials of the components
in contact with the fluids are PP (polypropylene), a material that is resistant to a wide range
of chemicals or compounds.
The maximum operative temperature
cannot
be over
70º C
for.
It is not recommended to use this kind of fans with solvents or with higher temperatures.
Ask however to TECNOPLAST Italy in case of variations of the operative conditions than
discussed during offer and order to check the effective reliability of the equipment
After installation, the device working is automatic, thanks to remote connection with
switches and doesn’t need intervention, with the exception for ordinary and extraordinary
maintenance operations explained later in the manual. (page 12)
The electric installation must
obligatorily
include the standard protection for the motor.
It is recommended to use protection grills or nets on the suction points, to avoid the
entrance of external bodies as rags or other objects that can cause damage the fan when in
contact with the moving impeller.
The installation of the fans with solutions and fittings parts different to what indicated, raise
the manufacturer from any responsibility about their inefficiency in case of damaging events
as meteorological (rainstorms, hail, wind, etc…) and should be verified and evaluated by
expert installers.
The fan is not suitable for the transport of solids in the air flow. This operating mode will
lead to the destruction of the fan.
The ducts on the intake and delivery sides must always be open. A closed duct will lead to a
rise in temperature which could cause the destruction of the fan.
The minimum air speed through the fan is 5 meters per second.
