Silflex

®

Silflex ducting products are designed

to handle extreme high and low temperature air

handling applications ranging from -80°F to +550°F.

They are not recommended for applications involving

the movement of liquids or abrasive materials, or for

negative pressure applications. This ducting is extremely

flexible and can be easily installed around obstructions

and sharp bends. Typical applications include electronic

equipment cooling, paper processing equipment,

engine compartment air handling, and fume removal

from aluminum and glass manufacturing.

Silflex Type SSF –

Lightweight and extremely flexible, this ducting

minimizes waste since short sections can be joined together to form a

continuous length. It features a single ply of silicone coated fiberglass

fabric with an internally exposed helical wire reinforcement.

Silflex Type DSF –

This ducting features a double ply of silicone coated

fiberglass fabric with the helical wire reinforcement encased between two

plies of fabric. The liner allows for improved air flow and less air friction loss.

Plus, it also provides a higher pressure rating than the Silflex SSF.
