We plan and manufacture filtration systems for almost all liquids.

Type of Product: Type - AKBF-R

Compact belt filter type AKBF-R


  • Grinding
  • Drilling
  • Turning
  • Milling
  • Honing
  • Eroding
  • Cooling water
  • Rolling
  • Drawing (wire - profiles - pipes)
  • Pre-filtration before ultra-filtration
  • Sludge dewatering or waste-water purification
  • Cleaning degreasing and paint removal baths
  • Cleaning of heated frying and baking grease in food production sector

This system is successfully used to clean cooling lubricants, such as emulsions or low-viscosity machining oils in the metal-working industry.

With a considerably lower basic space requirement, the extremely compact AKBF-Rs achieves a much better filtration result with the same filtering capacity compared to conventional flat-bed belt filters - and that with a considerably smaller space requirement.

Compact belt filter

The constructive design ensures that, even when using thin filtering aids, such as filter fleece, large quantities of sludge and chips can easily be filtered and discharged. With its variable design, the shape (rectangular, oval, round) and position (right, left, top, bottom) of the infeed area on the side wall can easily be adapted to the plant circumstances. For example, with smaller filter models no lifting pumps are required. The soiled liquid then flows directly from the machine discharge into the filter.

Especially in the waste-water treatment sector, this system is often used as a pre-filter before the actual ultra-filtration or for dewatering flocculent sludge. By using certain filter fleeces, total purification of the waste water can be carried out. This eliminates the need for a chamber or frame filter press.

The advantage of the filter lies in its completely automatic, continuous mode of operation.

In contrast to ordinary bag or cartridge filters, no regeneration phase is required, and the actual filtration process is not interrupted.

Mode of operation

  1. The soiled liquid flows into the inlet box via an inlet connection mounted on one of the two side walls.
  2. The medium is braked with an integrated inlet brake so that it slowly flows into the recess formed by the filter fleece and carrier strap.
  3. The dirt particles are deposited on the filter fleece and form the filter cake.
  4. Following saturation of the filter fleece, the liquid level rises to the maximum height.
  5. As soon as this level is reached (float switch has floated up), the geared motor is switched on with a level switch to pull in new filter fleece (from a roll).
  6. As a result, the liquid level drops again and a new filtration process can begin.
  7. The used filter fleece is pushed out of the filtration chamber together with the dirt particles and then falls into a sludge box located outside.

Level switch Max. alarm/feed pump OFF (integrated in filter)

As soon as this level is reached (float switch has floated up), the feed pump must be switched off. The pump should then be blocked until the actual float switch for the filter drive has dropped down again and has switched off the geared motor.

Limit switch for filter fleece shortage

The (decreasing) diameter of the fleece roll is monitored with this limit switch. A signal is output beginning at an adjustable point. Then the filter drive must be switched off and the roll replaced (as you use a PLC controller, the output "Please change fleece roll on Filter No. ... " would be very helpful here).

Pushbutton for manual filter fleece draw-in

The pushbutton installed next to the terminal box (surface-mounted housing) is always ready. If a new fleece roll has been inserted, this is used to draw it into the filter drum. The geared motor for the filter drive runs as long as the pushbutton is pressed. If it is released, the motor stops (dead man's circuit).
