Abstract

A filter to strain the fluid is made of filter paper as the filter main body. It is wanted to have the shape of Round Straight or Round Tapered or Oval Straight or Oval Tapered or Oval with several holes (Dual Flange Oval) or Oval Tapered with several holes (Dual Flange Oval Tapered), in which both of its ends are completed with end covers or without end covers and seal. The main hole of filter is installed with perforated plate or expanded plate or spiral spring or it can also be added with a fin plate functioning as the flow director which is made to be able to touch the circumference side of the surface of filter paper main hole, placed in length towards the length of filter hole. Such perforated plate or expanded plate or fin plate can be made of an alloy steel resistant to rust Or without lamination or made of stiff plastic or of plastic with strengthener or other material of having the same function and placed in one axis with such a hole. In order to strengthen the filter body, the expanded plate or the perforated plate can be installed at the outer part of the body attached to the external axis at the filter paper. The spiral spring c,an be made of an alloy steel resistant to rust or without anti rust lamination or made of stiff plastic or of plastic with a strengthener or other material of having the same function and placed in one axis with mat hole.
