Welcome to Shamon Air & Filtration Shamon Air & Filtration import, manufacture and assemble quality products ensuring economical and practical solutions. In 1998 Shamon's growth forced them into a larger manufacturing and storage facility, located close to Auckland City central. Shamon has the benefit of experience from several multi-national European & U.S based suppliers enabling us to purchase product and utilise the latest technology and research to enhance our products and to better support our clients. Shamon offers a comprehensive range of products and services and continues to pursue all avenues of IAQ (Indoor Air Quality). We believe that with a continuous search for improvement and refinement we will provide major benefits to our clients. To supply the best products, using the latest technology while providing the highest quality service so enabling us to exceed our client's expectations. Best Store and Best BrandsAir Change’s Air Handling Unit (AHU) range consists of the NEXT-AHUTM and the ALPHA-AHU.
Designed to be used in large commercial systems and incorporates heat exchange technology to efficiently pre-condition high volumes of outdoor air.Commercial, retail and office buildings The need for good filtration is becoming more and more obvious to most people around the world. All human beings basically perform better with clean air and a healthy indoor climate. outside ac unit fan stays onResearch proves that high-efficiency filters effectively reduce the problems that small particles can cause for sensitive people. carrier thru wall ac unitsWhen outdoor air enters the ventilation system, pollution in the form of smoke, dust and pollen will deposit on fans, batteries and ducts. small footprint ac unitsIf the air filters do not perform as they should, the air flow in the system will be reduced significantly and the balance between supply and exhaust air will be distorted.
With efficient filters from Camfil, the balance is maintained and odours and particles are kept under control. The system can always perform at its best and will stay forever young. Camfil supplies a full range of air filters for air handling units and ventilation systems to provide clean air for high indoor air quality (IAQ) and a healthy and more productive working environment. Camfil has products for both air and gas filtration in commercial building and airports, among other facilities. Camfil filters are also the most energy-efficient on the market, helping owners to green their buildings by cutting the power consumption of their air handling systems and reducing their carbon footprint. Subscribe to Camfil newsletter For a retrofit project, enquiries are made about various fans and the performance data of the fans offered are then compared. It is important to remember that performance specifications based on calculations are generally not realistic. They tend to be far too optimistic because the maximum efficiency levels of the individual components (motor, drive unit, control system and fan impeller) are usually taken from catalogues for calculation purposes.
It cannot however be assumed that each component will actually achieve maximum efficiency under realistic conditions. Multiplying the optimum individual efficiency levels yields a far more favourable total efficiency than is possible at the actual operating point (Fig. 1). As a result of this error, the values obtained from calculation of the power consumption will be far better than in actual operation. To ensure that realistic values are acquired, ISO 12759:2010 "Fans – Efficiency classification for fans" explicitly recommends working with measured values when planning. As good as it gets ebm-papst can always be relied on to provide the correct values because what we measure and supply is the minimum configuration of a complete, ready-to-install fan assembly consisting of high-performance impeller, EC motor and control electronics. As these components are optimally matched, it is possible to achieve static total efficiency levels well in excess of 60%. These levels have been measured and entered in the Product Selector software.
Far higher figures quoted by other suppliers are always open to question.In addition to optimum efficiency, a RadiPac EC plug fan with GreenTech EC motor offers a whole range of advantages over other fans for air handling systems. Installation – simple and safe The high-performance impeller is mounted directly on the rotor of the external rotor motor. This saves space and permits balancing of the entire rotating unit in one clamping operation (Fig. 2). The electronics and motor are combined in a single unit (Fig. 3). Thanks to the integrated control electronics there is no need for an external frequency converter, which makes installation easy. As the motor and electronics in the motor system are perfectly matched and in close proximity to one another, additional electronic filters and shielded cables are also superfluous and no external motor protection circuit breaker is required. Air-handling units can be commissioned without the need for any costly adjustment, earthing or shielding work.
This means ‘Plug & Play’ for ventilation technology. The GreenTech EC motor helps to preserve resources without any supply risks. The efficiency of the mains-powered synchronous motor with electronic commutation (also known as Brushless DC or PM motor) far surpasses efficiency class IE4 – and manages to do so without using any potentially problematic rare earth magnets. Other permanent magnet motors of the internal rotor type that can deliver comparable efficiency levels require rare earth magnets. Hence the ebm-papst RadiPac is THE compact, efficient, user-friendly, sustainable all-in-one fan solution for air-handling units (Fig. 3). Background information: ecodesign directive The ecodesign directive for fans (EU 327/2011) specifies minimum efficiency requirements for fans driven by electric motors. The requirements first came into force in 2013 and will become more stringent as of 01.01.2015. They apply to all fans with an input power between 125 W and 500 kW and a drive performance range of 125 W to 500 kW.
