Indoor air handling units (AHUs) for offices, shopping malls, clinics, warehouses and other commercial and municipal facilities require a combination of high efficiency, good acoustics and long service life. They reliably provide clean air to people in the buildings without creating drafts or irritating noise.
Energy efficiency and acoustics play a particularly important role in the design of the centrifugal fan used for air handling systems. But they should also be dimensioned to be as resource-efficient as possible in terms of space requirements and the effort required for installation and maintenance. The main component of a fan for influencing product characteristics is the fan wheel.
General HVAC blower wheels from punker therefore combine pleasant acoustics, compact design, flexible application options and very high static efficiencies. In this way, we support you in complying with strict legal guidelines and standards especially with regard to energy consumption such as Fan Energy Index (FEI) and CEC Appliance Efficiency Regulations.

punker General HVAC Fan Wheels
The fan impellers of the punker General HVAC series have been specially developed for use in air handling units that have to meet the highest energy efficiency requirements, such as those specified by the ErP Directive or the Fan Efficiency Index (FEI). With their impeller geometry optimized for efficiency, General HVAC fan impellers cover a very wide operating range with maximum efficiency. This gives manufacturers of air conditioning units and plug fans for AHUs the opportunity to drastically reduce their number of variants and thus the costs and effort involved in supplier and warehouse management.
Benefits
Reduced costs over the entire product life cycle:
- Thanks to the delivery of balanced fan impellers with low system vibrations, no rebalancing is necessary.
- Lightweight aluminum design facilitates installation, extends maintenance intervals and thus increases the service life of the motor used.
- The wheel strength, which is tailored to the load requirements, increases reliability during operation and thus reduces replacement intervals.
- The acoustically optimized wheel geometry enables use in noise-sensitive environments without incurring additional costs for insulation.
Enables compliance with strict legal guidelines and standards
- especially with regard to energy consumption such as Fan Energy Index (FEI) and CEC Appliance Efficiency Regulations.
Applications
- Air Handling Units (AHU)
- Compact air handling units
- Modular air handling units
- Plenum Fans / Plug fans
- Kitchen boxes
- Box fans
- Air Cleaners

Case Study Air Handling Units
Citizen Industries is a leading manufacturer of air handling units (AHU), laboratory equipment and biotech equipment in India. In 2016, punker helped Citizen reduce the number of different fan wheels in its AHUs by 90% by switching to the General HVAC Line. The rationalization has saved our customers time and money while further increasing the energy efficiency of Citizen's air handling units - which in turn helps end customers save on operating costs.
Read the case studyCase Study Hall Ventilation
A European developer and manufacturer of technologically sophisticated air conditioning solutions approached punker with the task of developing and supplying a new and optimized fan unit for an existing hall ventilation system within just three months. The punker solution included a conversion from forward to backward curved fan wheels, a custom laser-welded housing and the supply of complete fan units that provide a significant increase in energy efficiency and a substantial reduction in sound pressure.
