Handings & Orientation
The correct handings and orientation directly impacts the airflow direction of the fan within the system or to minimise the bends in system design. Incorrect handing or orientation can result in inefficient airflow patterns and poorly captured fumes. Incorrect choices can also affect noise and vibrations levels generated by the fan. You should advise your fan supplier of the required fan handing and orientation at the point of order. A project can be stalled or delayed as fan suppliers will not process an order without this information. This ensures the product performs as required in your system.
Depending on the desired airflow pattern and the specific requirements of the extraction system, the impeller rotation can be set to LG (Right rotation) or RD (Left rotation). Multiple discharge positions are available but it is important to ensure that the right handing is chosen before installation. We do not advise that any contractors change the handing themselves, this can lead to the system only achieving 30% of the duty.

Additional Information
Other sizes within the S series range of fume extraction fans include the S15, S25, S30, S35 & S50 models.
For applications requiring a higher static pressure the STORM range which provides relatively low air flow rate against elevated system pressures may be more suitable.
All S models are available as carbon loaded ATEX protected, to zone 2 gas.
