Fluid Filters – VDHA

IECEX RATED CLOGGING INDICATORS FOR HAZARDOUS AREA – VDHA

The function of the VDHA is to inform the user when a filter element needs to be replaced due to the increased differential pressure measured across the filter element. This will trigger a signal and an operator can then make the system safe and change the element.

It has been designed to meet the requirements of hazardous areas around the world. This indicator has been approved for use in ATEX, IECEX, CSA, TRCU and UL zones by a notified body.
