The BoBuMix-168 is a large propeller mixer specially designed for use in fermenters and secondary fermenters in biogas digesters and a further development of the well-known BoBuMix mixer.

The large, form-optimised mixing propeller ensures rapid mixing in the shortest time, with low power consumption. The drive unit is a quiet, high-quality motor with an ATEX-design gear stage.

The A-weighted continuous sound pressure level is below 70 dB (A). Thanks to a flexible compensator, on which the bearing block is mounted and sealed, the pivot range can be continuously adjusted between +/-20°. Version for ceiling and wall installation available. Version available either galvanised or in stainless steel. Thanks to the large concrete formwork (optional) opening, the mixer can be installed or removed in one go without anyone having to work inside the fermenter.
