I hope you can see that it bears the design of a cone.

Now let’s get down to its definition.

Witches hat filter, or cone filters are devices inserted in most of the inline high flow applications.

The separation occurs within the separation media which removes the unwanted debris.

Always go for the witches hat strainers with the capacity to eliminate as much debris as possible.

Remember the entry of debris into many pieces of equipment could eventually result in major systematic damages.

This is ideally not what you wish for!

Avoid problems by paying for value and by that I mean you purchase your witches hat filters from trusted suppliers.

What is the unique attribute about the trusted suppliers?

Well, these businesses put customer satisfaction fast because they know they will need you again.

They commit their resources, efforts and time towards the manufacture of reliable cone strainers.

As a customer, you end up with and effective and economical protection for your valves, pumps and other important parts.

Pay attention to the fact that the temporary filters aren’t developed to be used instead of permanent ones.

But, what I’m I implying by that?

Well. The point is that you need to remove them from the pipeline the moment the initial start up is over.

Next, let me take you through the factors you need to consider when buying this equipment.

How to Install Witches Hat Filters/Cone Filter

Is this starting to get a little complicated?

Don’t worry.

I will take you through everything in simplistic ways to ensure you become an expert by the end.

Proper installation of the cone filters will save you from unnecessary maintenance costs incurred from damages.

One way would be that you install it with the pointy end facing the flow or downstream.

The other way would be that you install it in such a way that it is against the flow (upstream).

Keep in mind that the equipment is mostly pointed upstream.

Do you know why?

That makes it possible for the particles to collect from the outer sections inwards.

Bear in mind that this orientation works best in case scenarios involving higher velocity rates.

With that said, let’s consider the case where the equipment faces downstream.

The important point to remember here is that the center portion of the pipeline bears greater velocity.

Of course, that is in relation to the other sections of the pipeline.

Understand that they are these differences in velocity that usually cause the particles to collect in the centre section.

How much do you know about basket strainers?

One important thing you should know is that it bears the same orientation.

Well, the point is that the cone strainer would help a huge deal has a wide range of applications.

In fact, it can serve quite well in cases requiring the maximization of the open area ratio.

Let’s now look at its design.

Witch Hat Filters Design

The first thing you notice looking at a Witch hat strainer is its unique make.

As mentioned earlier in the article, it takes up the shape of a cone.

In most cases, you will notice the layers of wire cloth which serves as the filtration element.

It is important to settle for strong and rigid filter material because that helps you separate the debris more effectively.

You also will realize that the multilayer meshes are designed in a rather unique way.

In fact, the end product bears a uniform filtration structure and that facilitates more effective filter operations.

Whatever your needs are, consider getting a witch hat filter that minimizes resistance by a large margin.

Always go for the sort of equipment that is constructed from proper, strong and durable materials.

Also bear in mind that the outstanding cone filter design goes along way helping maximize the flow area.

Paying for value basically means moving out there and obtaining a witches hat filters that guarantee you reliable operation.

You will also learn that leading Witch hat strainer manufactures pay a close focus to the size of pores.

In fact, there are quite many providers in the market currently that are able to develop pores of as little as 1 micron.

However, what matters the most is that they succeed at achieving the appropriate micron rating.

Undoubtedly, that is exactly what you require to attain enhanced operations.
