Sintered stainless steel filters can be used continuously
General filters cannot be cleaned or regenerated and must be threw away once they become dirty. With Nichidai Filter’s “Cleaning Service,” many stainless-steel filters can be cleaned and used repeatedly. This reduces the cost of filter replacement and also improves the total cost of manufacture. In addition, we will propose the appropriate cleaning process for each product for which cleaning request is supplied.
