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 installe...


Multiple Fans for Greater Reliability with EC FanWalls

  An old ventilation system consisting of several old belt driven centrifugal fans needed an overhaul after providing compulsory supply and exhaust air to operating rooms for 42 years. The ventilation system was optimised for efficiency using multiple 2x2 ECFanGrid configurations to achieve the duty of the existing belt driven alternatives while reducing energy consumption and increasing plant efficiency.   Full FanWall Turnkey Solutions Our installation team provided a full service throughout the entire retrofit by organis...


Corrosion Resistant Stainless Steel Fans – Robust & Hygienic

The materials used to manufacture an industrial fan, whether stainless steel, aluminium, mild steel or polypropylene, will hugely affect the versatility and uses of that particular fan. The materials of construction used in a centrifugal or axial fan affect weight, hygiene, maintenance, longevity, and appearance. For corrosive environments and those within the food industry we offer a range of suitable materials including polypropylene and 304 or 316 stainless steels.   How is Stainless Steel Corrosion Resistant? Stainless steel has b...


The Importance of Shipping Warehouse Ventilation

According to energy advisors, warehouses spend on average 15% of their budget on energy bills every year. Mechanical ventilation can contribute to a high percentage of this spend. In this article, we explore the importance of effective warehouse ventilation. Like many hazards, poor ventilation poses a risk to employee health, machines and equipment as well as goods and products. To avoid negative impacts on businesses ventilation hazards must be eliminated. These include a reduction in productivity, a decreased yield, machines or equipment m...


Industrial Fans for Wind to Hydrogen Renewable Energy Generation

Because of the effects of carbon emissions on global climate change it is imperative that we start to think about a carbon limited future, one where alternative energy sources will be required to supplement the carbon-intensive sources that currently power our daily lives. Natural gas is available, but the supply is limited, and its costs are expected to rise because of increased demand. One promising solution to this problem is the direct use of renewably generated hydrogen in fuel cells or in internal combustion engines for transportation and...


Replacing a Fan in a Fume Cupboard – Choosing the Right Plastic Fan

An efficient exhaust fan is key to providing an effective fume cupboard that protects laboratory workers and technicians from exposure to toxic chemicals. New and existing systems must meet strict regulations with the correct exposure measures in place and yearly maintenance checks should be carried out to ensure that best performance and safety levels are maintained. Axair work with a wide range of companies that can offer maintenance packages for full service fume cupboard checks, but for those of you who have identified an issue with the ...


Material Handling Fans for Combustible Dust & Textile Fibres

Dust explosions can occur in any activity in which solid materials are treated and finely divided. Small sized particles are produced during manufacturing processes. Large particles fall while smaller particles remain suspended for unlimited periods. Powder is measured in microns. A micron is a unit of length equal to 10-4 (0,0001cm). Material handling fans are required where solid and bulky materials need to be handled or conveyed, for example in food processing or biomass applications. In food processing applications, the likes of flour, suga...


Fans for School Fume Cupboards

  School and University laboratories with a lot of activity generally contain several fume cupboards which helps in providing a fume free workspace. Laboratory environments in educational establishments that handle hazardous materials require specialised ventilation equipment. During school science experiments and demonstrations, it is commonplace to use fume cupboards. Fume cupboards capture and remove any harmful substances generated and reduce the exposure to a safe level. These include harmful gases, vapours, aerosols and particu...

Filter Fans: What is the difference between the FF & FPF?

The re-engineered FF series of filter fans offers an innovative easy-to-mount solution that requires no tools thanks to a simple click-fit design. Due to its enhanced construction, the FF considerably reduces the risk of water infiltration and increases operational safety. We explain the key differences between the FF series and the original FPF series of filter fans below.     Key Changes between the Old Style FPF and the New Style FF Range of Filter Fans         Click-fit rapid installati...


Corrosion Resistant Extraction Fans for Salt Spray Chambers

    Salt spray has a very potent effect on corrosion and not knowing how products react long term to a corrosive environment or chemical, can have devastating effects for the end user and the original manufacturer. Salt spray testing is a laboratory simulation of a corrosive saline environment that tests the performance of items on their surfaces after corrosive protection treatments including coating, galvanising, painting and anodising. Test chambers are designed so that this can be done in a controlled environment to ensure t...


Predictive, Preventive and Reactive Maintenance in Thermal Management

  Electrical equipment failures due to ineffective heat dissipation account for millions in damage and lost business every year. Ironically, more than two thirds of electrical system failures can be prevented by a routine maintenance program. Maintenance approaches can vary by application but are commonly referred to as predictive, preventive, or reactive. Each of these approaches has advantages and limitations, some becoming more frequently adopted with the availability of new technologies. Electrical cabinets control systems, autom...


Wastewater Treatment Ventilation: Polypropylene vs. Stainless Steel and GRP

Corrosive Gases in Water Treatment Environmental wastewater treatment plants face a number of challenges in terms of ensuring safe and effective ventilation due to the release of corrosive and toxic gases that occur across the various treatment processes. During the treatment process, the ventilation system must control hazardous substances, chemicals and gases such as methane, ammonia, phosphorous, pesticides and carbon dioxide. Consequently, wastewater treatment plants are, by their nature, one of the harshest engineering environments. To...

Extraction Fans for Indoor Swimming Pools & Chlorine Ventilation

We all know that chlorine is widely used to treat water for swimming pools in leisure centres and domestic pools. Through the process of pool water evaporation, an indoor swimming pool will continuously produce huge volumes of chlorine or salt-water vapour. The temperature humidity in the air and these chemicals added to the water make the environment very aggressive. So aggressive that the materials used must be corrosion protected. Ordinary comfort ventilation is not enough when installed into the environment of an indoor swimming pool. Th...
