The Rogerseller Torus In-line Exhaust Fan Motor
comes with up to 3 optional inlet ports for
Exhaust Vent connection.
Note:
The performance curve chart has been tested in conjunction with the Rogerseller Torus In-line Exhaust Fan Motor, with each
exhaust vent using 1x 90 degree bend on the inlet and 3m lengths of flexible duct connected to the inlet and outlet of the of the
exhaust fan motor.
If the installation requires further lengths of duct and extra bends then the installing technician will need to calculate and adjust the
performance curve as necessary (
Exhaust Motor specific performance information is supplied with the product or at request
)
Location
Careful location of the exhaust vent will help maximize the air-flow and exhaust fan efficiency.
Air being extracted from a room should always be able to be replaced with 'make-up' air.
It is also important to make sure the 'static pressure' of the system is in balance.
Make-Up
air is the amount of air required in order for the exhaust motor to work effectively. this air can come from and adjacent
room or outside (window vent, etc.). Insuffucient make-up air will result in depressurisation in the room, preventing the exhaust
system from adequatley removing the required air flow.
"What goes out must come in".
Static Pressure
refers to the resistance to airflow in a ventilation system’s components and duct work. The push of the air must be
equal to or greater than the resistance to the flow or no air will circulate through the ducts.
"Fan performance decreases as static pressure increases".
The ventilation system will not operate correctly if the static pressures are not balance and/or there is not enough make-up air
available.
