DRE - Basic series
In every case of gravity flow and pneumatic transport of powders or granulate dry bulk, the alveolar rotary air lock of the basic series has its place.
Its simplified conception with bearing shields against the joints ensures a good holding to depression and pressure (from -0.6 to 0.4 bar). This is why you can place the device beneath a filter or a cyclo-filter. For a pneumatic conveying, it's possible to choose a side passage with pipe connection.
This obviously depends on the transported product's characteristics.
As for all the devices of our range, if your installation requires a device with special dimensions, it's possible to create it at place or by adapting it.
