Screen vs Paper Fuel Filters for Small Engines 

Paper fuel filters use filter elements made of polymer resin (phenolic resin) treated cellulose. This filter paper is considered a nonwoven filter media. Polyester felt sheets are another type of nonwoven filter media used for inline fuel filters. 

Screen fuel filters use fine mesh screen filter elements. This screen is made of woven monofilament plastic or metal wires...

Porous sintered bronze elements faq, applications beyond filtration plus references

An FAQ section about sintering, porous sintered bronze fuel filter elements and depth filters

Fine particles suspended in a fluid passing through a depth filter may impact or run into the filter material and stick or adhere to it. This particle impact and capture is called adsorption.

Depth filters have complex, meandering and irregular interconnecting pores ...

Some Details About Bronze, Depth Filtration, Porous Bronze Filter Elements and How to Make Them

What is Bronze?
Traditionally, bronze is an alloy of copper and tin. Tin bronze is still the most common bronze alloy, and it usually has about 10 to 12% tin with copper making up most of the balance. Quite a few modern bronzes do not contain any tin at all.

Benefits of porous sintered bronze filter elements and how they are made

Light duty carbureted vehicles, Outdoor Power Equipment (OPE) and Powersports are heavy users of plastic inline fuel filters. Inline fuel filters are easy and fast to replace and provide filtration protection from debris, fine particles and other contaminants.

These fuel filters are also widely marketed as OE original equipment parts and ...

Compliant Fuel Shut-Off Valves and Plastic Fuel Filters

Fuel system components for outdoor power equipment

To start, mesh number, mesh size and micron size can be likened to the imperial system of measurement as it’s compared to the metric system. They measure similar things but have more to do with application or professional preference.

Many systems use in-line filters in combination with check valves or precision orifices for enhanced performance

Introduction
Miniature flow-control components such as in-line filters are usually installed in air, gas, vacuum and fluid flow systems to perform very specific functions related to flow control. It is frequently useful to pair critical components in complimentary combinations. Although the function of inline filters is often  ...

Inline Filter Physical Connections

There are many considerations in carefully choosing an inline filter. Common choices focus on the expected particle load and the chemical exposure. Sample tests will show that it works in the intended operating environment. However, critical options exists with the physical connections on in-line filters. This post will review connection choices for in-line filters: barbed, threaded, Luer and push-in connections.

Barbed Connections
A barbed connection has one or more ridges or barbs. This is the section of an in-line filter pushed into a tube during installation. Pushing a tube end over a barb causes it to expand and then ...

A look at how to match filter specs to your inline filter needs.

We all realize that it is important to select the right filter so that something doesn’t go wrong later. For example, perhaps the efficiency of flow is too low. How do you know you made the right choice? Well, we already know about chemical compatibility requirements (see my previous post, How to Choose an Inline Filter – Chemical Compatibility). Now we need to think about operating conditions. I will go over flow rate, volume of solids, operating pressure and ...

Selecting inline filters for chemical compatibility

Sometimes I feel overwhelmed when I consider how many different chemicals we encounter in our daily lives. This bleeds over into technical considerations at work. We need to know the chemical compatibility of metals and plastics. This is critical when it comes to choosing inline filters. In this post, I will go over the importance of chemical compatibility as well as some other tips to choosing components for your process.

Plastics and chemical compatibility
Chemicals can change a plastic’s physical properties. They can ...

Filter Mesh, Microns and Inline Filter Choice

Filtration is filtration right? Well, like all things technical it is not as simple as that when it comes to particle separation. The easiest way to start thinking about inline filter choice is by looking first at filter mesh. In this post I want to give you a simple mental picture of what filter mesh or screen is and an overview of how different sizes of mesh are described.

Filtration Basics
Fishing net is basically a filter used to separate fish from water. Like fishing net, filter mesh is woven metal wire or plastic strands which stops particles that are too large from passing through openings...

Selecting the Right Inline Filter

What happens when you set out to find the right inline filter? This is tougher when looking for a miniature filter. I always think about the one I have and go looking for another just like it. What if there is no specific example to replace? Try searching for how to choose a filter using Google. Sorting through what matters and what doesn’t is a chore.

I’m going to review some tips on how to think about filter features so you end up with more filter options with less effort.  This blog refers to commercial filtration. Choosing medical filtration involves different ...
