Exhaust Ducting
Exhaust ducting venting an
Airflow
Spraybooth to atmosphere should be designed and installed by a competent
ventilation engineer. In order to ensure the correct operation of the
Airflow
Spraybooth and also ensure that the correct
volume of air is extracted at its face, the complete ducting system should be sized so as to achieve a maximum pressure
drop of “80Pa”.
Generally speaking, all ductwork should allow air an uninterrupted and smooth passage from the fan unit to the point of
discharge. All bends or transition sections should be designed so as to maintain the cross-sectional area of the fan
discharge diameter and performance checks should be carried out upon completion of the installation. Please Note:
Customers whose solvents consumption requires them to comply with the Environmental Protection Act (E.P.A.) must
pay particular attention to the design criteria of such ductwork as detailed by the Act.
Specialist information and advice can be sought from
Airflow
Product Finishing Limited on the suitability of intended
ductwork systems. Please contact our Sales Department for further advice.

Noise
Please refer to the tables over to obtain information of test results obtained from typical
Airflow
Spraybooth
installations. Please Note: Specific individual noise levels should be obtained following installation of your
Spraybooth, as it is impossible for
Airflow
to predict the properties of the acoustic environment in which your
Spraybooth is to be sited.
Please Note:
Airflow
will be pleased to advise on suitable in-duct silencers for use with their range of Spraybooths.
Please contact our Sales Department for further information.
