Peflex 4PPGA - Flexible Ventilation - Aluminum
Peflex 4PPGA is a flexible insulated and perforated air duct for medical grade sound attenuation, C-UL S110 certified.
PRODUCT DETAILS
-
Constructed from two layers of pure aluminum and two layers of polyester, encapsulating a galvanized wire.
-
Internal duct perforated over more than 25% of its surface area for significant attenuation of airborne noise.
-
Additional membrane located between the internal duct and the insulation, eliminating any contact between the air flow and the insulation.
-
Corrosion resistant, fully water repellent, and able to withstand high operating pressures thanks to the unique quad-lamination process.
-
High flame resistance with non-combustible aluminum internal and external walls and flame retardant adhesive.
-
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.
USES
-
Designed for medical grade ventilation systems requiring noise attenuation and high pressure resistance.
-
Ideal for environments requiring strict control of flames and smoke, with excellent fire resistance.
