Low-volume fans are compact blowers designed to move modest airflows—typically 100 to 5,000 CFM—at low static pressures. They excel at spot ventilation, equipment cooling, and confined-space purging where high flow rates are unnecessary.
Models include axial, mixed-flow, and miniature centrifugal types, with housings from plastic composites to lightweight alloys. Noise-attenuated impellers and acoustic liners keep sound levels below 65 dB.
Direct-drive motors and optional variable frequency drives (VFDs) enable precise flow adjustment based on temperature or gas-sensor feedback. Low-volume fans offer cost-effective, easy-install solutions for targeted ventilation needs.
