FAN DESCRIPTION
AIM
Moves air with presence of corrosive gas/vapours that can be characterized by corrosive concentrations.
WORK CYCLE
- Aspiration: through the volute suction mouth the air is aspirated through a tube or directly from the
environment in which it is installed.
- Expulsion: the air can be directed into apposite pipes or into the outside air from the permanent mouth of
the volute.
MANUFACTURE
- Volute: plastic structure as described in the catologue, to direct the air with presence of gas/vapours moved
by impeller.
- Impeller: rotor with vanes, is put into rotation by an electric motor.
- Support structure: supports the parts which are used directly to convey air in the presence of gas/vapours.
- Motorization: mechanical system that gives the rotary mode to the impeller (in the model with suffix “T” there
is a transmission belt-pulley).
OPERATIONS
Direct the air with presence of gas/vapours
The fan, as effect of the rotation of the impeller, creates a depression that aspirates the fluid into the volute
and pushes it into the exit channel.
DESCRIPTION OF THE MOST COMMON ACCESSORIES
The fan has the following accessories that are available on request:
•
Anti vibration coupling: absorb the vibrations that can be transmitted in the tubes of the aspiration system.
•
Anti vibration supports: absorb the vibrations that can be transmitted to the support of the appliance.
•
Butterfly valve: regulates the capacity of air in the tubes.
•
Tubes: to connect the fan to the system.
•
Condensation discharge: unloads the condensation that forms inside the volute.
•
Curves and reductions: make up the junctions between the lengths of the pipes.
SAFETY DEVICES
The fan does not have active safety functions since it must be integrated in a system that controls feeding and control.
The buyer must therefore evaluate the risk of the appliance, on the whole, and adopt the necessary measures.
Uncovered moving parts (impeller) represent the main risk, which must be protected by protections in the areas of air entry and exit. These protections are usually represented
by the air channels, in the installation phase.
ENVIRONMENTAL CONDITIONS ALLOWED
The fan can be installed in the work environment with a temperature between -15C° and +70C° and not exceeding 1000 metres above sea level (with the exception of
particular agreements with the manufacturer)
.
WORK PLACE REQUIREMENTS
SUPPORT SURFACE: Dimensioned so that it can support the weight as declared in the catalogue as well as loads that are already present and must be sufficiently stable to
avoid possible falls.
NECESSARY CONNECTIONS: Electric and aeraulic.
WARNING
The products, object of this instructions manual, are not suitable for operation in explosive atmosphere (Atex).
Explosive atmosphere is generated by inflammable gas (methane, hydrogen, petrol vapours, thinner, acetone, etc…)
For use in explosive atmosphere, the user must purchase from Venplast srl, fans that are certified CE ATEX
with a category that conforms to the classified area in accordance to Legislative Decree 81/08.
TRASPORT
TRASPORT DATA
The fan must be transported inside a box or a pallet.
DANGERS
The fan must be handled as it has been delivered, it is heavy and has sharp and protruding parts which are dangerous and therefore the necessary individual items of pro-
tection must be used.
The equipment must be cleaned carefully before handling, in order to avoid debris from work processing falling inexpectably during lifting operations.
PRECAUTIONS TO BE ADOPTED
WARNING: take care at all times.
WARNING: wear suitable accident prevention clothing.
WARNING: follow the procedures of this manual extremely carefully.
WARNING: make sure the lifting parts are adequately oversized for the weight needing lifting.
Do not for any reason go near the equipment if it has not touched the ground and if the lifting measures are not active.
HOW TO TRANSPORT THE PACKAGING
WARNING: for safety reasons do not handle weights exceeding 25 kg by hand. If so carry out lifting operations together with other operators or use appropriate lifting devices.
•
Lift the packaging and place it on the support surface inside the means of trasport.
