ZFAN Technologies, LLC is dedicated to serving HVAC&R manufacturers for their product
development and engineering needs.  It differentiates itself with unique skill set in air-moving
technologies and team of professionals who are,

  • Highly creative technical experts with track record of successfully developing proprietary air-moving
    technologies and patents;

  • Strong analytical skills with the abilities of relating the real-world problems to complicated analysis and
    translating the results into practical design solutions;

  • Exceptional abilities of using airflow and acoustics fundamentals to scrutinize the complicated
    situations and drill down to the root of the problems;

  • Technologically savvy problem-solvers who understand strength and limitations of varied computer
    simulation tools and apply them to solve the real-world problems effectively;

and have achieved technical successes including,

  • Developed swept-blade axial-flow fan technologies and reduced air noise of condenser units by over 6-
    8 dB through effectively controlling boundary layer growth.  The swept-blade technologies have become
    the standard-bearer of today’s “super-quiet” residential and commercial condenser units

  • Developed forward-curved(FC) centrifugal blower technologies through blade and housing optimization
    and turbulence control, improved air efficiency by over ten percentage points while reduced air noise
    by over 6-10 dB for classroom unit ventilator and downdraft cook-top air-moving systems.

  • Developed plastic multi-blade forward-swept non-even spacing engine cooling fans for forklift trucks
    and achieved substantial noise reduction, performance gain and structural integrity through design
    optimizations.

  • Developed PMDC plastic axial-flow fan assemblies with airfoil profile blades and energy recovery
    vanes , increased total efficiency by 10-15% over the existing products for automotive A/C condenser
    and engine cooling applications.

  • Developed and optimized evaporator blower and condenser fan for rooftop RV air-conditioners and
    PTAC, achieved substantial system performance gain, sound and energy reduction though air flow
    optimization and air load balancing of single motor driven system.

  • Developed high pressure induced draft combustion blower for gas furnace and water heater, achieved
    substantial pressure capability increase over the existing technology with the same mounting footprint.

  • Developed a CFD program for blade design optimization and a fan design software to successfully
    eliminate cut-and-try cycles of traditional fan design routines.
