Answer / waqas

Strainers and filters usually do the same thing i.e. trap
the particles.
Now the term strainer is used for the device which separates
macroscopic particles i.e. more than 200 mesh or 74 microns.
The filter separates particles finer than 74 microns.
Phani was right saying that the i saw filter filtering the
particles of 40 microns.

thank u

Answer / phani

hi lakshman
so which one is accurate
i thinking that filter can filter micro level
strainer can filter coarse sizes
in any gas lines, i saw strainers
in naphtha lines i saw filters of 40micron type

okey
thank u

Answer / b.srinivas

Strainer for coarse size, filter is more accurate than
striner.

Answer / farzad

Actually there isn’t any since a strainer is, in reality, a
coarse filter. The question is then one of semantics.
Generally it is assumed that if the particle to be removed
is not visible to the naked eye, the unit is filtering, and
if the particle is visible, the unit is straining. The
average human eye can detect a specific particle between 50
and 70 micros. Most people cannot see anything smaller than
325 mesh, or 44 microns. Since 200 mesh is equivalent to 74
microns, a general rule would be that if the screening
device is coarser than 200 mesh, it is a strainer and if it
is finer than 200 mesh it is a filter." - Factory Direct

Answer / k.a.a.m

The purpose for the strainers & filters are the same , to
trap undeeded particles

The filters normally are filled (Packed) with sand ,
gravel , cotton and etc.
Filters normally used to purify the liquids that are used
in the very sensitive sets

Strainers; are normaly made of steel and or pvc ,
perforated and ccovered with a fine mesh , the stainers are
normally hollow from inner side, and used to filter gases
and water with hi influent

Answer / abdul hameed

Filters can act as Strainers. But Strainers can not act as
Filters.

Answer / zeeshan memon

Strainers and filters are both products that separate solids from fluids. However, when the solid to be separated is visible to the naked eye (greater than 25 μm) then the term “strainer” is used and when separation is smaller than or equal to 25 μm, the term “filter” is used.

Answer / datz_15

The difference between stainer and filter is that srainer
is used to remove coarse particles of 150 microns while
filter is used to removed fine particles or impurities of
40 microns.Filter is used commonly aboard ship for
lubrication or fuel system to prevent seizure fom the
moving parts of the main engine.
