PK By-pass Element with Plastic Connectors 1x75 (Type A)

The PK series by-pass element (also known as a crossover bridge or air tunnel) is a specialized installation component designed for the cross-over bypass of ventilation routes, flat ducts, or other utility lines in conditions of restricted installation height.

The "Type A" modification features a bypass recess depth of 54 mm, allowing it to safely cross over utilities up to 50 mm in height (for example, 200x50 mm flat ducts). The use of high-impact plastic connectors in the PK series ensures rigid fixation of the flexible duct and guarantees consistent joint airtightness. The housing design is engineered to minimize aerodynamic resistance while maintaining a low profile.

The unit housing is constructed from galvanized steel, which is resistant to corrosion and mechanical loads from building structures.

Design Features:

• By-pass Geometry: The 54 mm recess depth enables passage over obstacles up to 50 mm high without increasing the overall floor slab thickness or suspended ceiling height.
• Plastic Connectors: Equipped with an integrated end seal that ensures a high airtightness class without the need for additional sealants or sealing tapes.
• Mechanical Fixation: The locking latch system on the connectors securely blocks the flexible duct, preventing it from slipping out during floor screed pouring or under air pressure.
• Installation: The housing is equipped with mounting lugs for rigid fixation of the unit to load-bearing slabs.

Technical Specifications:

• Housing Material: Galvanized steel
• Connector Material: High-impact plastic
• Number of Ports: 1 inlet / 1 outlet
• Connection Diameter: 75 mm
• By-pass Recess Depth: 54 mm
• Overall Dimensions (LxWxH): 371 x 180 x 85 mm
• Compatibility: 75 mm round flexible ducts and flat objects up to 50 mm in height
