Description

Product Description

Castle Flexible Duct Connectors isolate equipment vibration and noise from the ductwork system. The fabric strip connects between AHU, fan or equipment flanges and the duct — absorbing vibration, thermal expansion and misalignment. Available in Silicon coated (-30°C to +250°C), PVC coated (-30°C to +80°C), and Neoprene materials. All dimensions available in rectangular and circular.

Vibration Isolation
Fabric strip breaks mechanical connection — prevents fan/AHU vibration transmitting to ductwork and building.
Thermal Expansion
Absorbs duct thermal expansion and contraction — prevents stress on duct joints.
High Temperature
Silicon-coated version withstands up to +250°C — suitable for kitchen exhaust and industrial applications.
All Shapes & Sizes
Custom manufactured to match any rectangular or circular duct dimension — no standard size limitations.
ISO 9001:2015 Certified
Quality management system certified by IGC, covering all stages from raw material to final delivery.
SMACNA & DW144 Compliant
Manufactured to the latest edition of SMACNA HVAC Duct Construction Standards and DW144.
Custom Sizes Available
Non-standard dimensions manufactured to project specifications with competitive lead times.
Approved by Leading Consultants
Accepted by Dar Al-Handasa, ECG, SYSTRA, Khatib & Alami and 25+ major engineering consultants.
