Leak-free hermetic fan
Thread Content
Could any expert recommend a leak-free hermetic fan for me? The requirements are: an air volume of 500 cubic feet per hour, an air pressure of around 5000 pascals; it should be able to maintain this pressure at 3000 pascals for about an hour. It would be ideal if the fan has a small size. Thank you
The fan isn’t a problem; this parameter is simple. The fan needs to be equipped with shaft seals, and sealing strips should be used for the connections of the inlet and outlet ducts. It also depends on the layout of the ducts – for example, a valve should be installed at the fan’s inlet
For leak-free sealing, labyrinth seals or seals using inert gas can be employed; the choice depends on the requirements of your industry application. This parameter is simple – what matters most is the level of sealing performance. If budget permits, it’s advisable to choose a higher-quality fan.
