Filter With Service Indicator

  • In pneumatics, the operating pressure is one of the major criterion for end performance. The reduced output pressure due to obstruct in the air flow could affect the end performance.
  • Air filter is the product which removes the dust particles, water particles etc. from the compressed air.
  • The filter element has to be changed/replaced periodically to ensure the air flow and the pressure is maintained in the system to achieve the end function.
  • Air filter with service indicator indicates the condition of the filter element. If the filter element is clear then the air flow and the pressure is maintained at the desired level. If the filter element is dirt and chocked, the air flow and the pressure is restricted thus resulting in low end performance.
  • Green colour indicates the filter element is clean. The air flow is smooth and the pressure drop is well within the limit. 
  • Yellow colour indicates the filter is chocked. The air flow is restricted and the pressure drop is beyond the limit.
  • Red colour indicates the filter is dirty and chocked. The air flow is fully restricted and the pressure drop is above 1 bar. At this stage the end function would get affected because of high pressure drop.
  • These color indications will alert the user about the conditions of the filter element as mentioned above for further necessary action (i.e. cleaning / replacement of the filter element). Air filter with service indicator is available in the following size: Air filter with gauge type- 1/2", 3/4", 1"; Air filter with indicator type - 3/8".
