Pressure belt-type filter

  • BK 3 - 6 (filtration area 3 - 6 m)


Pressure belt-type filters are used for cleaning contaminated coolants used in the metal shaping industry and in the metal rolling industry. Cleaned coolants have a longer service life, improve the surface quality of the worked material or rolled material and assist the heat exchange at the point of contact.


  • high performance
  • no back wash during regeneration
  • easy filter cake removal
  • short regeneration time
  • problem free use of various synthetic belts
  • washing facility for high and low pressure
  • competitive price

mode of operation

The pressure belt-type filter fulfils the requirements of filtration without any waste disposal problems based on a standard equipment with a continuous synthetic filter belt. A filter belt cleaning device is installed in the head of the belt-type filter. The closing mechanism of the seal flaps, low positioned pneumatic cylinders and the adjustable protection guards keep the machine height low, which facilitates easier installation and handling. The chambers are held closed even in the event of air pressure failure due to a self locking toggle mechanism.


The standard equipment of the pressure belt type filter includes:

  • pneumatic control system
  • filter belt washing unit
  • slotted screen as filter belt support
  • continuous filter belt
  • take up reel for additional filter media
  • holder for additional filter media
  • all electric control devices wired to a common terminal box
  • 2 pack protective coating

areas of application

Pressure belt type filters with operational areas of between 3 6 m are normally used in centralised coolant systems with a high circulating volume.

During the process the range of separation assisted by the developing filter cake is between 10 100 m. Also instrumental in the primary filtration is the nominal fineness of the filter cloth used. The basic capacity of the filter is 1,500 l/min/m filtration area.

However, the viscosity of the coolant, the material being processed and the type of process can greatly vary the through-put. The actual filtration performance can therefore be between 500 2500 l/min/m.

With the addition of filter support medias such as diatomaceous earth or cellulose the filter can also be used as a precoat filter in more difficult filtration applications.

The specific throughput rates in question are the filter-specific base capacities. They represent reference values for the interested customer. F.E.S. supervises each filter completely from the initial request to the turnkey handover to the future operator. Each filter system is specifically designed and custom-tailored to the case of operation at hand. For this purpose, we utilise our experience values, company-internal laboratory tests and, if necessary, mobile test installations for application 'on location'.
