What are pneumatic filters?

Pneumatic filters are specially engineered tools that keep pneumatic systems running smoothly by eliminating impurities from compressed air, such as water and oil vapour. A 'media' is often utilized to trap particles while letting air pass through. A type of membrane can also be used instead of a media, enabling only air to pass. Filters for pneumatic air are frequently used in conjunction with pneumatic air lubricators. 

Importance of pneumatic filters

Pneumatic filters are regarded as a necessary component for preventing pneumatic equipment failure. They keep the pneumatic machinery working efficiently, effectively cleaning compressed air from water and all other contaminants. Using pneumatic filters, thus, helps in removing impurities and enhances the life of the components. They can be used in a wide range of industrial environments encompassing food processing & beverage packaging, medicine, analytical instrumentation, manufacturing, aviation, marine, and so on.

Types of pneumatic filters

There are different types of pneumatic filters available in the market. The most common types include:

• Primary filters: Primary pneumatic filters are responsible for protecting pneumatic devices from any potential damage by eliminating contaminants like small water droplets, aerosols, and dirt particles. Particles as small as five micrometres can be removed by these basic filters.
• Secondary filters: Secondary pneumatic filters can trap particles as tiny as 50 nanometres. They can filter out gases, odours, moisture, oils, fumes, and other fine particles from the air.

Other than these two basic types, pneumatic filters are also available in varieties like pneumatic water separators, pneumatic particulate filters, pneumatic coalescing filters and absorbing filters. These types of filters can filter out water, dirt & particles, rust, and oil respectively.
