Ventflex ASPA - Flexible ventilation - Semi-rigid - Aluminum or Stainless Steel
The Ventflex ASPA is a semi-rigid ventilation duct made of aluminum or stainless steel, perforated for acoustic attenuation, with thermal insulation R4.2, R6, and R8.4.

PRODUCT DETAILS
-
Constructed from a single strip of aluminum or 316 stainless steel, without the addition of adhesive.
-
Perforated on 20% of its surface to reduce noise generated by the air and the mechanical system.
-
Corrosion resistant, with a lower coefficient of friction than standard fabric ducts.
-
Standard length of 10', with the possibility of compression to 48''.
CURVATURE DIAMETER
1-1.5 times the duct diameter.
