Why Refurbish AHU’s with EC Plug Fans

Old buildings can often feature outdated and deteriorating ventilation systems. The first opinion may be to replace the entire air handling unit, but often refurbishing the components within the system can prove beneficial beyond financial gain. This week we look at the advantages of AHU refurbishment over replacing the entire system. One major problem in favour of refurbishment is that of the existing system. Ductwork and max air volume delivery are often governed by the existing ventilation system, so the new one must comply with these sp...


Industrial Fans for Dust & Solid Transportation

Industrial and manufacturing processes and procedures can often produce hazardous and combustible airborne particles such as dust. This particulate must be extracted out of the working environment in order to protect other processes and any susceptible personnel. Axair, in partnership with Casals Ventilation, can supply a range of fans that can be utilised in local extract or multi-point ducted systems to remove these particles safely and efficiently. Material handling fans are required where dust, solid and bulky materials need to be handle...


Noise Optimised Units for Fan Coil Units

Vibration induced noise can be a major problem in fan coil installations. It originates within the motorised impeller unit and cannot be entirely eliminated until new technology invents an induction motor that is free of electromagnetic vibration and an impeller that is perfectly balanced.] Ecofit believe they have gone a long way towards solving the problem by introducing double inlet centrifugal fans that incorporate anti-vibration mountings between the fixed shaft and the scroll mounting arms. The fans, prefixed ‘GDS’, therefore achie...


Effective Redundancy by Running Fans in Parallel

The air handling unit market is under constant pressure from all sides; pressure from the end user to improve indoor air quality, pressure from architects to provide more comfort and to produce more aesthetically pleasing units but also from energy consultants who demand manufacturers to deliver energy efficient units with higher airflow performance and pressures at lower installation and operating costs. Commercial heating and ventilating represent a major proportion of any construction budget, frequently comprising ten percent or more of t...


Fume Cupboards & Alarms

Axair’s Labair controls range has been created for applications involving hazardous fume extraction such as fume cupboards and chemical cabinets. There are two models available A and C, both of which are available in a standard version or Digital. Both the A and C series are white with 3 push buttons: fan on/off, light on/off and alarm mute. They also feature a green LED light that illuminates to signify that the airflow is OK, a red LED light that flashes to alert that the air speed is too low and a sash high LED which starts flashing whe...


Better Fan Efficiency – The New Ecofit V8 Motor

Axair Fans are excited to introduce the latest addition to our EC Technology product range. The high power EC motor known in the industry as the “V8 motor” is a new external rotor motor with input power up to 300Watts manufactured by our innovative and reputable supplier partner Ecofit. For our existing customers, the V8 motor replaces the L4 motor, with the advantage of higher power at a lower speed enabling a better overall efficiency. Previously the external rotor motor collection consisted of the G9 with input power to 150Watts, and L4 ...


The Importance Of UV Protection For Fan Filter Units

The UV protection of a fan filter unit for an enclosure is an element that rarely factors into the purchasing decision when selecting fan filters or fan filter units. This element should not be overlooked especially if the enclosure is going to be situated outside. UV protection may seem irrelevant but without adequate protection, the shiny new unit will soon become an eyesore making it look old and outdated.  UV degradation can be a huge problem. It can make the plastic crack and disintegrate causing irreparable damage. This means having to ...


Alerting Live Enclosure Voltages with The Flash Signal Device

The maintenance and inspection of electrical enclosures should be carried out under safe and efficient working practices. The latest product from Axair’s innovative supplier partner Fandis, the flash signal device is designed to aid this maintenance while also complementing the existing range of internal components available for the effective performance of electrical enclosures. Using The Flash Signal Device The device is designed to indicate when a live voltage is present when an enclosure door is opened. With three red flashing signals t...


HVAC Fan Failure Monitoring

A method of detecting fan failure within fan coil units in heating and ventilation. The undetected failure of fan coil units is a long standing problem in heating and ventilation. Fan coil units like the types found in H&V applications tend to be unmonitored and system fan failure can often go unnoticed to the point where a refit or refurbishment is required or where air simply ceases to flow from the ductwork. The oldest format for monitoring the FCU is to use differential pressure switches. Within the fan coil unit, the installer would ...


FLL Series LED Enclosure Lights

Usually, when we discuss enclosures we highlight the importance of effective heat dissipation and thermal management to prevent the premature failure of equipment housed within the cabinet. This usually means using a fan filter unit or associated thermostats or anti condensation heaters respectively, but Axair Fans are excited to launch a brand new set of accessories to our portfolio - our LED Enclosure Lights. All enclosures or electrical cabinets require regular maintenance and it's common for these units to be tucked away in a convenient ...
