Description
Product Description
Castle Inertia Registres (Counterbalancing Registres) automatically balance airflow in different sections of le ductwork using counterweights ou springs. They modulate blade position based on air pressure, maintaining consistent airflow distribution without manual adjustment. Essential pour systems avec variable fan speeds ou multiple branch takeoffs.
Self-Regulating
Counterweight mechanism automatically adjusts blade position — no manual intervention ou power required.
Fail-Safe
Gravity closes blades when airflow stops — prevents reverse airflow et backdraft.
Low Maintenance
Non moteurs, actuators ou electrical connections — purely mechanical operation.
Adjustable Sensitivity
Counterweight position adjustable to fine-tune opening pressure threshold.
ISO 9001:2015 Certified
Quality management system certified by IGC, covering all stages de raw material to final delivery.
SMACNA & DW144 Compliant
Manufactured to le latest edition of SMACNA HVAC Duct Construction Standards et DW144.
Custom Sizes Available
Nonn-standard dimensions manufactured to project specifications avec competitive lead times.
Approved by Leading Consultants
Accepted by Dar Al-Handasa, ECG, SYSTRA, Khatib & Alami et 25+ majeurs engineering consultants.
