Filters are used in almost every industry, from the HVAC at your local shopping mall to the car you drove to get there, filters ensure clean fluids make their way into our equipment, industrial facilities, and environments.
Filtration is a powerful, but often overlooked tool. Effective filtration supports our goals of reducing carbon emissions, reducing maintenance costs, improving reliability, and increasing productivity.
Contamination comes in the form of dust, dirt, or other matter that either physically or chemical degradation. Filters remove this before they can enter ventilation systems, combustion engines, or controlled environments.
Filtration improves efficiency at a microscopic level, removing these contaminants which can otherwise introduce resistance, generate heat, and create wear.
One example, A diesel fuel injector has tight tolerances oftentimes in the 2 micron range. Modern diesel engines require very clean fuel in order to achieve proper atomization of diesel fuel and optimal combustion.
Filter costs are influenced by size, material, and efficiency.
Filter Size: A larger filter has higher dirt holding capacity, but capacity can also be influenced by construction A higher number of filter pleats equates to a larger surface area for fluids to flow across and dirt to accumulate.
Filter Media: Air and Hydraulic Filters can be created from a variety of different materials. Cellulose, Spun Glass, Plastic, or even Metal filters. Each material type will balance cost, durability, and uniformity.
Filter Efficiency: Efficiency is determined by the size and uniformity of the pores within the filter media. A filter with a high “Beta Ratio” will be more effective is capturing particulate.
Multistage or “Compound” filtration has the unique ability to balance cost, efficiency, and performance by deploying coarse and fine filtration is series.
When a filter becomes saturated with contaminants flow could be restricted and additional energy is consumed in order to achieve the same level of performance.
Instead of large particulate filling the pores of a fine membrane by placing a coarse filter in front of a fine filter contaminants will fill the pores of a larger membrane while the smaller particulates pass through before they are captured by the pores of the small membrane.
The practice of multistage filtration can cut your filter costs in half while doubling your maintenance intervals.
The cheapest filter may not be the best filter for you
While a cheap filter might be easy on your wallet in the short term. The wrong filter may cost you more elsewhere in the form of energy loss, increased maintenance costs, or component failures.
Smart filtration saves money and creates value!
