Short pressed bends with seals

Short pressed bends are designed for building ventilation systems
based on SPIRAL ducts and plain ducts. Seam welds provide air tightness
class D without the need to use any other sealants.

In ventilation and heat recuperation systems, the double EPDM gasket provides
air tightness class D according to EN 12237. The piece is connected with
a duct by inserting one into the other. The short bending radius helps
installing the ductwork under a suspended ceiling with a limited clearance.

BPKFL bends feature a female joint for direct connection to the mounting
frames of various air valves (e.g. KN-RM or KWO-RML).
