Q&A:
1. Q: Why choose a HINOTEK Fume Hood?
Choosing HINOTEK means investing in proven reliability, performance, and value. With nearly 20 years of manufacturing expertise, we offer an extensive portfolio of nearly 40 models Fume Hood, including ducted & ductless, all rigorously quality-controlled and backed by dedicated global support. Our efficient production provides you with premium technology at a competitive price.
2. Q: Should I choose Constant Air Volume (CAV) Systems or Variable Air Volume (VAV) Systems?
A: Please overview the table:
| Feature | Constant Air Volume (CAV) | Variable Air Volume (VAV) |
| Airflow Principle | Exhausts a constant volume of air at all times. | Varies the exhaust volume based on sash position. |
| Face Velocity | Variable; increases as the sash is lowered. | Constant; maintained at a set point regardless of sash position. |
| Energy Efficiency | Low; highly energy-intensive due to constant maximum exhaust. | High; significant energy savings by reducing exhaust volume. |
| Upfront Cost | Lower initial purchase and installation cost. | Higher initial purchase and installation cost. |
| Operational Cost | Very high due to wasted conditioned air. | Significantly lower due to energy savings. |
| System Complexity | Simple, with fewer components and easier maintenance. | Complex, with sensors, controllers, and variable-speed fans requiring maintenance. |
| Safety Profile | Provides basic safety, but face velocity can fluctuate. | Enhanced safety due to stable and consistent face velocity. |
| Ideal Use Case | Labs with very few hoods, constant-demand processes, or strict budget limitations on initial capital. | Labs with multiple hoods, variable usage patterns, and a focus on long-term operational savings and sustainability. |
3. Q: What kind of quality and support can I expect?
A: You can purchase with complete confidence. Every instrument undergoes strict quality control before shipping. We provide expert remote installation and training support to get your team running quickly.
