Energy Efficient Fan Filter Units (FFU’s)

  Optimising the performance of an FFU based system within cleanroom and containment applications offers significant energy saving opportunities. High efficiency EC technology lies at the centre of reducing energy consumption in fan filter units, even when systems vary due to airflow path and operating conditions. FFU manufacturers have risen to the challenge of reducing costs with the development of improved control and EC motor technology. A cleanroom can be up to 50 times more energy intensive than an office building because of th...


EC Plug Fans for Powder Control & Clean Room Applications

Ventilation & Energy Efficiency are the key areas to consider when designing a cleanroom for powder control. Clean rooms are vital when it comes to ensuring powdered medicines are contamination free during and after the manufacturing and packaging stages. Investing in new technology in addition to adopting hygienic handling techniques are paramount to effective clean rooms. Not forgetting air ducts and ventilation areas to facilitate the airflow and pressure required to ensure the required number of air changes per house and pressurisation ...


Our Versatile AC Compact Axial Fans Range

Axair Fans UK has the most comprehensive selection of AC Compact Axial Fans on the market. Starting with the smallest, Axair offers the Costech 60mm square x 30mm thick frame size, a popular size for DC fans but rarely seen as an AC fan product. At the top of the range is the ECOFIT 280mm square x 80mm thick frame size, again not widely available. This fan utilises an IP44 protected external rotor motor which is capable of delivering 1705m³/h airflow. The cast aluminium frame provides a choice of mounting centres. The full range of AC co...


Fandis Roof Mounted Panel Fans

The Fandis range of roof mounted panel fans provide extra cooling for temperature-critical electrical equipment. Available in T or TP Series these roof mounted panel fans provide superior top mounted cooling for enclosures that demand more than regular enclosure filter fans. The ‘T’ Series is a plastic structure with an aluminium top. Due to its smaller size the range has a low profile housing, only 90mm deep. The T range are designed for top mounting on the outside of cabinets, providing high level extraction of hot air whilst taking-up...


The Role of Industrial Fans in Pharmaceutical Downdraught Benches

Downdraught benches are an essential part of the pharmaceutical industry as they provide a safe workspace for weighing, sampling and packaging powdered medication. The sector have strict guidelines to follow to ensure the health and safety of staff in the workplace and this includes ensuring that the correct equipment is in place and an efficient ventilation system is integrated and well maintained. With the integration of mechanical fans, downdraught benches are effective in eliminating the risk of staff being exposed to potentially potent, ac...


The Schematic Structure of EC Motors

Rosenberg EC motors (EC = electronically commutated) are inverter-fed synchronous motor with permanent magnets in external rotor design. The AC mains voltage is rectified in the commutation electronics of the EC motor. A downstream inverter provides the motor with the motor voltage depending on the position, similar to the principle of a frequency inverter. In opposite to this, all parameters are already optimally matched to each other. The intelligent EC commutation electronics decide how the motor phases in the stator are supplied with cur...


Formaldehyde and Xylene Fume Extraction in Mortuaries

Formaldehyde, xylene and hot paraffin wax fumes are all chemicals used within mortuaries as a method of preserving and embalming the body. Toxic chemicals such as these pose a serious health risk to mortuary staff who face long term exposure. Having the correct fume extraction systems and equipment in place is vital to protect the health and safety of staff and visitors. There are many reports of the toxic effects of exposure to these chemicals but very little documentation on the importance of efficient fume extraction systems for their remova...
