FAQ
Question: What is a magnetic levitation (Maglev) blower?
Answer: Maglev blowers use magnetic force to levitate the shaft, resulting in zero mechanical contact, no wear, extremely low noise, and energy savings over 30%.
Question: How do fume hood fans control air speed?
Answer: They typically work with Venturi valves or VAV systems to automatically adjust fan speed based on the sash height, maintaining a constant face velocity for safety.
Question: What is a portable confined space ventilator?
Answer: This is a small axial fan with flexible hosing used to purge toxic gases and supply fresh air before workers enter spaces like manholes or tanks.
