More than 40 years ago, the sandy and gravelly soils of the Netherlands - and subsequent engine failures - demonstrated that foam and paper filters provided pilots with airflow but did not protect them.
Twin Air's breakthrough, dual-layer combo design unites performance and protection.
Fused layers of open cell foam and fine foam inside trap even the smallest particles.
The new rounder design increases airflow. This also goes for the minimized seams, made possible by a revolutionary micro-aggregation process: shorter seams = more foam = more flow.
- with flowable, recoil-resistant foam laminated to the inside of the filter
- washable and reusable (it is usual to repeat between 40 and 50 times)
- two-layer foam (made to specifications with cells of equal size and distribution)
- high quality (assembled by hand and checked for a perfect fit)
