Product Overview

• The Rochester 3-Ply Polyester Panel filters incorporate three distinct filter layers permanently heat-sealed around a galvanized , 9-gauge internal wire frame
• The first layer acts as a high-porosity impingement filter, the second a high-density interceptor and the third as a durable strainer to prevent unloading or streaming.
• A non-migrating tackifier between the second and third laminates assures positive filter-cake build up
• This filter achieves a high level of efficiency on a wide range of particle sizes
• Since there is no external support struture necessary, all of the media surface is exposed to the air stream
• The Filtration Group 3-Ply filters may exceed the performance and service life of rigid, pleated filters
• They offer the additional advantage of being self-gasketing, friction-fit frames that can often eliminate the need for extra mounting hardware
• When used as pre-filters, these filters will add substantially to the life of more expensive high efficiency filters
