Remove particles and maintain systems and environments with filters using CThru Mesh® precision expanded metal foils
Filters are used to improve the quality of everything, including the air we breathe, water we drink, food we eat, systems that run machinery, and a staggering array of chemical processes that allow us to drive the needs of every industry. With so many required use cases, it’s no surprise that filters come in all shapes and sizes. The design and features of a filter used for maintaining hydraulic fluid in a power transmission system are completely different from a filter used in a medical environment to maintain air quality. Despite their vast differences, expanded metal foil can be used to provide structural integrity, increase surface area, and filter out particles from a wide array of fluids and gasses.
CThru Mesh® Provides Filter Strength and Design Flexibility
Filters must maintain the targeted fluid quality in a variety of challenging process environments. High pressure systems filtering particulate to maintain infrastructure performance require strength and durability to ensure continuous operation. Fluid or gas flow speed, density, and particulate volume dictate different required surface area configurations for appropriate filtration. These somewhat opposing vector points of strength and design flexibility are easily brought together by using CThru Mesh® to perfect the filter application. CThru Mesh® can be designed using the appropriate material thickness (available as thin as 25 microns) to provide the filter membrane the support and strength required for the installed environment. At the same time, CThru Mesh® is easily formed to any filter design, from standard sheet to pleated filters. When you incorporate CThru Mesh® into your filter design, it will withstand the designed flow rate and potential pressure changes from particulate build up while maintaining the appropriate shape to facilitate the particle removal process.
CThru Mesh® Designed and Manufactured to Your Filter Rating
The primary function of any filter is to remove particulates from the fluid flow and maintain the targeted level of fluid quality downstream from the filter installation. The design of a filter is typically centered around the size of the particulate to be removed, or the “Filter Rating”. The filter rating is determined by the minimum particle size that the filter should stop from penetrating the filter membrane. These ratings are typically done in microns. So, a filter rating of 20 would remove particles 20 microns and larger. For context, a human can identify white particles on a black background down to about 40-50 microns. CThru Mesh® comes in pore sizes as small as 250 microns (.010”) and can be combined with other membrane media to trap and remove particles at your target filter rating.
Flame Arrestors and Spark Arrestors Use CThru Mesh® Precision Expanded Metals
While not exactly traditional filters, flame arrestors and spark arrestors perform a very similar task to protect equipment and people from inherent dangers of combustion systems. Flame arrestors are designed to let hot gas pass through the component while preventing open flame from escaping the system. At the same time, spark arrestors are used to contain particles in exhaust from internal combustion engines, preventing their escape to the surrounding environment. Both devices protect the immediate area from fire and unsafe conditions – and are mandatory for small engines in the state of California. Flame arrestors and spark arrestors are perfectly suited to leverage CThru Mesh® expanded metal foil as the critical material to maintain the safety of the system.
