90° and 45° Pressed Ventilation Bend with EPDM Seal for Round Ducts

BPKL/BPKFL

90° and 45° Pressed Ventilation Bend with EPDM Seal

A short pressed ventilation bend designed for SPIRAL ducts and smooth ventilation conduits. Linear welding guarantees Class D tightness without additional sealants. The double-lip EPDM rubber seal ensures compliance with tightness class D according to PN-EN 12237. Connection to the ventilation duct is made by inserting it into the duct. The small bending radius allows for saving space between ceilings. The BPKFL version has a socket dimension on one side, enabling direct connection to mounting frames of ventilation valves, such as KN-RM or KWO-RML.
