Deflector
DF
The DF deflector is designed for vertical air discharge through the roof in natural and mechanical ventilation systems, including DU and DUV smoke extraction systems.
It can be directly combined with STAM roof curbs (except STAM 310 and STAM 500) or connected to OZA and OZA-DUV fans via OZA-PET adapters. The deflector is used for roof air discharge in DU systems, when fans are located inside the building.
Design features:
aerodynamic shape to increase draft using wind flow;
-
external drainage system for rain and snow protection (experimentally verified);
-
built-in ejector to reduce exhaust flow temperature;
-
four-point mounting on any STAM roof curb;
-
available in galvanized or stainless steel;
-
provides maximum weather protection without moving parts.
