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 (e.g. the ErP), especially with regard to energy consumption.

punker General HVAC Fan Wheels
The General HVAC fan wheels from punker have been specially developed to meet the technical requirements of the HVAC industry. They are particularly suitable for plug fans and plenum fans used in unhoused applications, such as Air Handling Units (AHU). The fan wheels of the General HVAC Line are designed for high energy efficiency, low noise emission, low weight and optimum use of available space, and offer a convincing price/performance ratio. They cover application ranges up to 4.000 Pa (16 in WG) static pressure rise and achieve a static efficiency of up to 78%. Different materials, joining methods and wheel-motor connections allow flexible use, also with regard to a wide variety of drives.
Benefits
- use free-running or in confined spaces
- energy-efficient blower wheel enables savings in operating costs
- very high efficiency facilitates achievement of ErP specifications
- compact construction allows space-saving system design

(PDF, 415 KB)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.
