Auto Bypass Fume Hood
Auto Bypass Fume Hood Manufacturer and Supplier in India
RJ LAB CRAFT INDIA PVT. LTD. is a trusted manufacturer and supplier of high-performance Auto Bypass Fume Hoods designed to provide superior operator protection, consistent airflow performance, and efficient containment of hazardous fumes, vapors, and airborne contaminants. Engineered for advanced laboratory safety, our Auto Bypass Fume Hoods help maintain stable face velocity even when the sash position changes, improving both safety and operational efficiency.
Designed for modern laboratories handling critical chemical processes, our Auto Bypass Fume Hoods offer intelligent airflow management, durable construction, and reliable long-term performance.
What is an Auto Bypass Fume Hood?
An Auto Bypass Fume Hoods is a ventilated laboratory enclosure equipped with an automatic bypass system that adjusts airflow as the sash opens or closes. This design helps maintain more consistent face velocity, reduces excessive turbulence, and improves containment performance compared to conventional fume hoods.
When the sash is lowered, the bypass opening allows additional airflow through the hood to help maintain safe operating conditions. This makes Auto Bypass Fume Hoods suitable for laboratories where stable airflow control and enhanced user protection are important.
