In aspiration and industrial ventilation systems, there are two basic concepts of system design –
- Positive pressure systems – where the main fan is in front of the filter
- Negative pressure system – with the main fan behind the filter
In terms of energy consumption, as well as the laws of physics, it is always harder to push than to pull…
That is why we focus our solutions on negative pressure units, which have a number of advantages over positive pressure units
– There is no waste air going through the main fan, only purified air.
– The main fan is always clean, which aids in cleaning efficiency and system operation
– There is no risk of sparks, fire or even explosion in the case of unfavorable conditions.
– Sparks are easier to control
– Capacity of the installation is limited only by the filter capacity, if necessary, to increase the capacity you need only to add an additional fan.
– Energy costs are significantly lower compared to positive pressure systems.
– These advantages are not available in positive pressure systems.
Carefully calculate the volume of air and waste to be evacuated
Pressure relief valves must be installed in case all pipes in the plant are clogged due to the fault of maintenance personnel.
