Pressed Ventilation Elbow 90° and 45° for Spiral Ducts

BPK/BPKF

Pressed Ventilation Elbow 90° and 45°

Short pressed ventilation elbows are designed for efficient connection of spiral ducts and smooth ventilation pipes. Their construction with a small bending radius allows for space saving, which is crucial in installations between ceilings. Available in 90° (BPK-90/BPKF-90) and 45° (BPK-45/BPKF-45) variants, they provide design flexibility.

Key Features

Application: For spiral and smooth ducts.
High tightness: Ensured by a linear weld.
Safe installation: Rolled edge protects against hand cuts.
Space-saving: Small bending radius ideal for tight spaces.
Easy connection: Inserted directly into the duct.
BPKF version: With a socket dimension for direct connection to ventilation valve mounting frames (e.g., KN-RM, KWO-RML).
Material: Galvanized steel sheet.
Available angles: 90° (BPK-90/BPKF-90) and 45° (BPK-45/BPKF-45).
