Air Filters for Industrial Engines

An industrial air filter is a device specifically designed to prevent any molecular contaminants or solid particles from entering an engine.

Industrial engines require clean air in order to maintain and maximise performance – industrial environments are subject to a number of pollutants such as dust, wear particles, emissions etc. all of which can have a negative impact on the overall performance of the engine.

A good quality air filtration system provides a wide range of benefits to engines in both commercial and industrial settings:

• It will prevent harmful dirt and debris from contaminating the engine, which may ultimately lead to engine failure
• It can significantly enhance engine and equipment performance
• Lower fuel consumption
• Minimise Co2 emissions

If the engine is not clean it loses efficiency and water may get into the engine.

What Are Industrial Air Filters Made From?

There are several different types of filtration media used for air filters – the material used very much depends on the intended application of the filter and of the size of the particles being filtered – in most air filters some type of cellulose media is used.

Donaldson are one of the world’s leading air filtration manufacturers, offering an extensive product range with unique patented products such as; Donaldson Endurance™ Air Filters made with Ultra-Web® Nano fiber Filtration Technology, PSD PowerCore® Air Cleaners, PowerCore® G2 Filtration Technology etc. as well as other products such as the Donaldson TopSpin™ Pre-Cleaner, designed to extend the life of existing air filters.

How Often Should Air Filters Be Changed?

This depends on the application of the filter and its surrounding environment – many manufacturers offer a wide range of air filter accessories to help extend the life of the product, such as Donaldson air intake systems which are designed to prolong the life of an engine by offering advanced filtration technology. Such systems may come with replacement filters, air cleaners and other accessories.  Most filters will typically come with a warranty – this may vary however, depending on the manufacturer.

Finding the Right Air Filtration System

Types of Air Cleaners

There are numerous air filtration systems available on the market to suit every possible industrial application. Air cleaners however, are typically divided into two types – one stage air cleaners and two stage air cleaners. The former are generally used in environments where there are less contaminants, such as on-road. The latter, are typically used in medium to heavy industrial environments such as construction, mining and agriculture etc.

When searching for the most suitable air filtration system it is important to consider the following:

• What is the type of machine and what environment will it be working in? Light duty, light to medium, medium, medium to heavy or heavy duty?
• Calculate the air flow requirements – this can be done using either the ‘Engine Displacement’ equation or the ‘Engine Horse Power’ equation.
