Tribute to R Vijayakumar (Vijay)

AERFIL was established in 2006 in Liverpool, NY to provide expert consulting in particle measurements, contamination control, and air filters and filtration. While our goal is to serve small and medium size companies, we also work with start-ups that are too small to have resources in-house but need the expertise ‘On Call’ to compete in the market.
We believe in the ancient Indian philosophy that knowledge grows by sharing.

Although we are a for-profit enterprise, our services are offered regardless of your ability to pay. We expect to succeed by helping you succeed by offering our Training, Education, Mentoring, and Collaborative Research for your business.
