Duct Damper for Fume Hood
.jpg)
Product Code : SCL-WDF-11666
Engineered for precise volumetric control within high-velocity chemical exhaust systems, this Duct Damper balances static pressure in fume hood installations. Adhering to ANSI/AIHA Z9.5 standards for laboratory ventilation, it is designed for University research facilities and Vocational (TVET) engineering labs to maintain safe face velocities and hazardous gas containment during experimental procedures.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Manual Adjustable Flap Valve. -> Outcome: Allows students to quantify changes in static pressure and face velocity, supporting practical application in Fluid Dynamics and HVAC Engineering Module 402.
Feature: Corrosion-Resistant PP Construction. -> Outcome: Facilitates hands-on maintenance training in environments handling volatile reagents, reinforcing protocols in Occupational Health and Safety (OHS) Vocational Curricula.
Feature: Variable Position Locking. -> Outcome: Enables students to calculate and balance airflow distribution across manifold systems, supporting the "Analyze" and "Evaluate" levels of Industrial Ventilation Design.
International Logistics & Compliance
Our global supply chain operations are structured to meet the rigorous requirements of international procurement officers and ministry-level distributors. All units are secured in export-grade seaworthy crating (ISPM-15 compliant) to maintain structural integrity during multi-modal transit. Documentation provided with every consignment includes the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification protocols, and Technical Installation Manuals in English. The hardware features a tropicalized design, tested for structural stability and chemical resistance in operational environments reaching up to 45°C and 90% non-condensing humidity.
Why Source from the OEM?
Procuring directly from the OEM ensures total vertical integration and technical accountability. Unlike third-party traders, our facility manages the entire production cycle, including in-house injection molding of high-density polypropylene components to ensure uniform wall thickness and chemical resilience. Every batch is tested for uniformity in blade closure and seal integrity against traceable pressure standards. We maintain direct factory spares availability, including replacement handles and pivot assemblies, providing institutional buyers with a 10-year support window and eliminating the downtime risks inherent in non-standardized third-party components.
