Low energy, low noise

The compact GYROPURE filter fan offers maximum media area in an optimized shape that preserves ideal internal flow velocities and eliminates energy-wasting turbulence.

Media face velocity typically range from 0,5-2,5 m/s, inlet velocities from 3-10 m/s and exit velocities from 6-15 m/s. Hence also the ductwork occupy minimal space.

The large number of particles provides inherent self- balancing as the filter loads.

A key enabling component is the proprietary impeller, which semi laminar spreads high- velocity inlet air and contributes roughly 50% of the total pressure rise across the filterfan ensuring shaft to air power fan efficiencies close to 1.

By keeping tangential velocities and Reynolds numbers low (typically < 9 m/s), noise is maintained below 30 dBA@1m. The low noise advantages apply also at higher velocities and even HEPA filtration. 

Self sealing pleat packs can be placed in compartments for balance and easy filter change.

Long-life‍ ‍

Coriolis separation is an inherent mechanism in the filter fan that keeps most of the pleat inlets open throughout the lifetime of the filter media.

On the coarse level, the impeller blades perform the primary separation by accumulating dust directly adjacent to the blades. Finer particles, such as pollen, are carried into the pleats closest to the impeller and gradually fill them — similar to how a vacuum cleaner bag fills.

In the final stage, even smaller particles (from approximately 4 µm and above) are separated within the pleats, leaving one side of the pleat essentially clean.

These effects significantly moderate the pressure increase across the filter over its lifetime. Since a large portion of the filter fan’s total power consumption is related to the pressure drop across the media — while the aerodynamic conditions around the impeller remain relatively stable as the filter loads — thereby maintaining excellent fan efficiency over the filters service life.
