TYPE-EFR EXCELER FILTER (Filter paper reuse type)

Like the conventional EXCELER FILTER, this filter performs pressure filtration --> removal of filtrate by air --> removal of filtration cake, but also enables the automatic recycling of filter paper by using an unrolling motor to unroll the filter paper.


  • This reduces the frequency of filter paper replacement and the operator's workload.
  • The effective use of filter paper without loss can reduce the running cost of the equipment, reduce industrial waste, and consequently improve the environment.
  • New filter paper is gradually being supplied so as to keep the equipment clean.

Automatic operation start1.Automatic operation start
When the AUTO RUN button is pressed on, the air cylinder moves the bottom lid up to form a filter chamber.
At the same time, both the top and bottom lids are firmly sealed with a particular formed packing bonded to the top lid.
After complete sealing is confirmed, the next filtration process begins.
Filtration process2.Filtration process
The automatic liquid supply valve opens and the filtration pump starts simultaneously.
Raw liquid from the filtration pump enters the filter chamber for filtration by the filter paper there.
During filtration, the filter paper captures all solid contents in the raw liquid as deposited on the paper. This deposition reduces the flow rate and increases pressure in the filter chamber.
The filtration process ends at activation of the filtration timer or at the detection of upper-limit pressure.
Dewatering process3.Dewatering process
When the filtration pump stops, the automatic liquid supply valve closes and the automatic dewatering valve opens.
Compressed air is jetted into the filter chamber to expel any residual liquid with its pressure.
Activation of the dewatering timer or detection of the lower-limit pressure confirms that no residual liquid is left in the filter chamber.
The automatic dewatering valve closes and the dewatering process ends.
The air cylinder then pulls the bottom lid down to open the filter chamber.
Cake removal process4.Cake removal process
When the filter chamber is confirmed as being open, the paper feed motor runs to take up filter paper by the length used for filtration.
The dewatered cake on the filter paper is removed by flipping the filter paper and using a scraper to deposit the cake in a cake box.
At the end of paper take-up and cake removal, the EXCELER FILTER returns to the first process and automatically repeats the series of filtration processes.
ペーパー巻戻5.Paper rewinding process
When the dewatered cake is removed, the paper rewinding motor runs to automatically rewind the filter paper towards the filter chamber.
This enables the automatic recycling of filter paper and reduces the frequency of filter paper replacement.
When the unrolling of filter paper ends, the EXCELER FILTER returns to the first process and automatically repeats the series of filtration processes.
