The recently introduced helicopter product is a direct replacement for oil wetted filters. Using advanced synthetic dry media technology, it is cleaned using water only and Pall says it virtually eliminates maintenance associated with conventional filters.

The company adds that the Dry Barrier Filters are also highly durable and resistant to corrosion.

“Oil-wetted inlet barrier filters are adapted from 1950s automotive air filtration products and have been due for updating to 21st century technology for years,” said James Hardy, global product manager for Pall Aerospace.

Pall Aerospace and DART Aerospace will be displaying the range at Heli-Expo in Orlando, United States from March 3-5.

“We’re pleased to introduce the next product in our PB portfolio and give more operators an opportunity to experience oil-free filtration.”   The PB100D filter for the Airbus Helicopter AS350 joins the PB110D for the Bell 206L/407 as the first in a planned series of certifications for direct fit replacements for Bell 206L/407 and Airbus Helicopter AS350 barrier filter installations.
