Peflex 3PPA - Flexible Ventilation - Insulated - Aluminum
Peflex 3PPA is a C-UL S110 certified insulated flexible air duct designed for sound attenuation thanks to its perforated duct and offering high pressure resistance.
PRODUCT DETAILS
-
Constructed from one layer of pure aluminum and two layers of polyester encapsulating a galvanized wire.
-
The internal duct is perforated over more than 25% of its surface, providing significant attenuation of airborne noise.
-
Corrosion resistant and fully water repellent, able to withstand high operating pressures thanks to tri-lamination.
-
High flame resistance with non-combustible aluminum outer walls and flame retardant adhesive.
-
Vapor barrier composed of two layers of metallized polyester laminated with fiberglass, ensuring intensive resistance to puncture.
-
Low internal friction coefficient, reducing system energy consumption.
-
Standard length of 25' in a 48'' box.
CURVATURE DIAMETER
0 times the diameter of the conduit.
