Filtering systems are products and equipment designed to purify, clarify and remove suspended debris from fluid and gaseous process streams. Though single filters may suffice, optimal filtration is often achieved through the use of several filtration products used in conjunction with one another to create a complete system.

Filtering System Design
Filtering systems may employ several different techniques or simply the succession of similar but progressively restrictive apparatus. Often incorporated at the point of intake and exhaust as well as inline configurations, these systems promote safety all throughout the manufacturing process. To accommodate complete air or fluid systems, filter media include such varied products as strainers, cartridges, membranes and housings, each of which may be designed to remove large particles from industrial process streams or with the precision to purify water for drinking by removing even microscopic contaminants.
Applications for Filtration Systems
Filtration Systems are used to clarify coolants, corrosive chemicals, gasoline, oil, hydraulic fluid, lubricants, water, air intake and exhaust air, filtering systems are easily divided into two major categories: air filters and liquid filters. Despite this division, many of the same techniques are used for each, but with minor adjustments. Membrane, pressure and vacuum as well as electrically charged filters are among the most commonly used to remove impurities in flow lines for many industries, including food and beverage processing, chemical, pharmaceutical, mining, pulp and paper, automotive and agriculture. Commercial and contexts likewise utilize filtering systems with great frequency in order to promote health and safety for homes, offices and for the environment.
Things to Consider When Purchasing Filtering Systems
With such variability, there are several important factors to consider when installing a filtration system. The degree of installation must first be considered. Filtration equipment can be portable, mounted or centralized systems, the latter being the most complex. This decision also has a significant impact on the type of filter and collection as it relates to the ease of cleaning or replacing components. As some filtering systems should run continually, it is important to consider the downtime required for maintenance. The pressure drop or ability to operate through blockages will also impact the frequency of cleaning and repairs. Additional considerations include filtration rate, filter location, stream viscosity and temperature, filter load capacity, maximum flow and absorption.
The particular type of filter will determine many of these variables as will the material used in its construction. Housing and filters may be constructed of aluminum, steel, stainless steel, steel, carbon, sand, durable plastics, Teflon, nylon and other synthetic fibers. The particles themselves should correlate to the specific filter. Both the size and chemical composition should be compatible to ensure product longevity and efficiency. Regulatory bodies, such as the International Organization for Standardization (ISO), may require certain filters be used in a given application, though many configurations can result in similar competence.
