CGR-filter cloth

CGR Type filter cloth means Caulked and Gasket Rim. This kind of design does not use the filter cloth to seal the chambers. The CGR filter cloth is caulked into a groove. A second O-ring is installed in the rim area to seal the chambers (see also the pics below).

This type of filter cloth offers some essential advantages:

  • The CGR type filter cloth is clamped in a groove around the filter chamber. The filter chamber and the filtrate drainage ports are sealed by an O-ring made from EPDM, NBR or Silicon.
  • There is no leakage and no drip tray required. No unpleasant smell because no liquid passes the seals, no problems with maximum allowed concentration of emissions around the filter press.
  • The surface of the filter plate pack is easy to clean and it looks better because no liquid is passing out of the chambers.
  • The filter press looks much more professional and sophisticated.
  • No loss of compressed air during cake blowing because the chambers are sealed.
  • While chemical cleaning of the filter clothes are in process, no cleaning agent, like acid or other stuff is leaking out of the plate pack.
  • The function of filtration and sealing of the filter chambers are spited while using CGR filter elements
  • The filter clothes are selected by filtration aspects only.
  • The sealing of the chambers are independent from the filter cloth, made by best possible engineering manner.
  • The O-ring seals around the filter chamber keeps the liquid inside the plate pack, leakage of liquid or gas is reduced to a minimum.
  • There are lots of different seals possible , like EPDM, NBR, Silicon etc.
  • The edge of the filter cloth is made in a way to be clamped in a groove. There for an O-Ring or a road is sewed all around the filter cloth.
