The ProfiDrum CombiBio is the symbiosis of all our experience in the area of mechanical and biological filtration, resulting in a “Turn key” solution: you just connect the in- and outlets to your pipeworks and connect the power plug. The system is based on the principle of a “moving bed” using the new ProfiDrum biocarrier that is brought into movement using integrated aeration. The system is fully equipped including air pump and integrated high pressure pump (for the RDF cleaning), all contained in a secured and dry chamber *.

The ProfiDrum CombiBio can be delivered in three compact sizes, with a maximum flow of 20m3, 30m3 or 50m3 liters of water. Both our CombiBio 30 and CombiBio50 product can be combined with a specifically designed showerfilter that suits perfectly on top of the filtration system. This add-on is specifically designed for the demanding customer who wants to max out their biological filtration possibilities that exceed the maximum capacity of their CombiBio system.This option is also available for already installed systems and can be retrofitted!

The ProfiDrum CombiBio-series includes a control box and high-pressure pump for an effective and efficient cleaning cycle.

ProfiDrum is a specialist in designing and building professional filtration systems based on Rotary Drum Filters (RDF’s), optionally combined with biological filtration solutions.

Proven and True Reliability
ProfiDrum is trusted by universities, aquaculture facilities, aquariums, zoos, professional dealers and hobbyists worldwide to provide reliable filtration solutions for maintaining pristine aquatic conditions.
High Flow rates
ProfiDrum RDF’s can filter up to 250000+ liters per hour. With the standard Stainless Steel mesh screen, waste particles down to 70 microns in size are filtered. Custom screen mesh sizes from 40 to 300 microns are available. The ProfiDrum Control Box activates a cleaning cycle to maintain an optimal flow rate when enough waste accumulates in the mesh screen.
Stainless Steel internals
316 Stainless Steel internal hardware is standard on all ProfiDrum models for performance and durability.

No compromises, only the best material are good enough for your solution and our products.
Automated cleaning
The ProfiDrum Controlbox was designed from the ground up with reliability in mind. Utilizing relay logic, the ControlBox keeps the ProfiDrum running 24/7. The ProfiDrum Controlbox handles the cleaning and operation of the ProfiDrum. Input from the sensors lets the ControlBox know when it’s time for a screen cleaning.

Rotary Drum Filters (drumfilters) remove solid waste from water using a fine mesh screen. The fine mesh screen traps waste particles, while allowing water to flow through. Sensors tell a connected control box when it’s time to rotate and clean the filter. Fully automated, no hands dirty!

During the cleaning cycle, the control box rotates the drum and activates the high pressure spray bar. The spray bar removes the trapped waste from the fine mesh screen and directs it into the stainless steel waste tray.
