Pneumatic filter

From Free net encyclopedia

A pneumatic filter is a device which removes contaminants from a compressed air stream.

Usage

It is now common to have various stages of filtration employed in a filter-regulator-lubricator form factor, usually with the different filter housings connected. Air filtration applications are diverse and include end-user sectors such as cleanroom environments, biomedical, analytical instrumentation, food processing, marine and aviation, agriculture, manufacturing, food and beverage packaging and a host of other uses.

Primary filters

Typical commercial pneumatic filters will remove particles as small as 5 micrometres from the air. The filters protect pneumatic devices from damage that would be caused by these contaminants. These contaminants include lubricant particles ejected by the compressor, dirt particles and small water droplets.

Secondary filters

Secondary filters are used for a variety of applications and can remove particles as small as 50 nanometres in size. These secondary filters can remove fumes, odors, vapor, mist, moisture, oil, and tiny particles from the air stream. In addition special air dryer devices are used to condense moisture from humid air and deliver a clean, dry supply of air, mostly used with sensitive equipment such as fine printing and laboratory use.Template:Tech-stub
