Gram Silo filter type S-CJF

After several customer requests, we have chosen to resume the production of the silo filters type S-CJF, now in a simplified version with the same efficient automatic filter control as in our CJF-units.

In connection with the filling of silos with dusty material, a dustfree equalization of overpressure will typically be needed, and this with a separation degree that ensures compliance with applicable emission limits. With separation degree according to dust class ”M”, according to DIN EN 60335-2-69 Appendix AA (separation degree > 99.9%), it is ensured that the overpressure air does not:

  • contaminate the surrounding environment
  • cause health problems for the employees
  • lead to damage to equipment around the silo

S-CJF is easy to bolt on top of silo, filters outlet air and lead filtered material directly back to silo.

Unit is as standard made in galvanized powder enamelled plate and is therefore suitable for outdoor use. For silos covered by ATEX, the silo filter S-CJF is also available in an ATEX-version with relief for own volume.
