Swimming Pool Extraction Fans: Corrosion Resistance

Chlorine is widely used to treat water for swimming pools in leisure centres and domestic pools. When extracting chlorine fumes from areas such as plant rooms and storage cupboards after dosing, the air may be corrosive. If this is the case, it will need to be extracted via a polypropylene fan and plastic ductwork as metal systems would corrode over time. ATEX Requirements Chlorine has the potential to become explosive when mixed with certain other chemicals. Therefore, the swimming pool extraction system may need to be ATEX (Atmospheres Expl...


Fans for School Fume Cupboards

During school science experiments and demonstrations, it is commonplace to use fume cupboards. School fume cupboards are designed to capture and remove air-borne hazardous substances generated during laboratory experiments to reduce the risk of exposure to a safe level. These include harmful gases, vapours, aerosols and particulates. Fume cupboards prevent potentially dangerous vapours being released into the classroom in two main ways; through ducting or through filtered, recirculated air. Ducted fume cupboards draw air through the sash ope...


Hospital Chemical Storage Ventilation

Hospitals require a number of potentially hazardous chemicals in day to day maintenance, cleaning, sterilisation, testing and operating applications. The health care sector represents one of the largest users of chemicals in the UK. The storage of these chemicals involves a number of considerations in terms of temperature, ignition control, ventilation and segregation. In this article, we focus on chemical storage ventilation. The ventilation of chemical storage areas is of paramount importance to ensure clean air and a safe environment for ...


Corrosive Fume Extraction in the Water Treatment Process

To provide water that is safe for human consumption, there are a number of processes that the water treatment industry use. Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralises the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. To separate the floc from the water, it is allowed to settle and fal...


ATEX Fume Extraction for Landfill Organic Waste

Landfill gas is a natural byproduct of the decomposition of organic materials which are put into landfill. The gas is composed of roughly 50% methane (CH4) and 50% carbon dioxide (CO2) and a small amount of non-methane organic compounds. Methane is a potent greenhouse gas and is harmful to the environment. When organic waste is first deposited into landfill, it goes through the initial stages of decomposition where small amounts of methane are generated. As the conditions change during the subsequent stages of decomposition, an increase ...


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...


SEAT Industrial Range Evolutions

Since our partnership with SEAT, Axair Fans has always had an impressive selection of Corrosion Resistant Polypropylene fans for use within hazardous atmospheres and ATEX applications in addition to a wide range of installation accessories. As a technical product engineer for the SEAT range and the one in the know when it comes to polypropylene applications, Andrew Ward reports on the old and new developments that Axair Fans has seen over the past few years. Let's recap by looking at the features of the well known S and ST range of fans: SE...


Laboratory Fume Extraction Roadshow

Following on from the Effective Laboratory exhibition at Strathclyde University on 1st March 2016, Axair Fans took to the City of Nottingham to showcase new developments and energy efficient air movement technology while sharing our technical knowledge and experience of laboratory air movement. Held on Wednesday 21st September, the event saw delegates attend breakout sessions to discuss and learn more about effective laboratory design and system integration. Particularly interesting was the focus regards how an enhanced laboratory design can...


Impressive Efficiencies In Fume Extraction

A common control within laboratories for the prevention of explosive and hazardous substances is by using a fume extraction system. Axair Fans has a wide range of corrosion resistant polypropylene fans for use within Industrial, Commercial & Educational fume extraction. There's nothing more exciting for our technical engineers than seeing the largest fan in their range leave the building. Especially into an application perfectly suited to its main features. Powerful, energy saving and quiet, it's hard to ask for more from a fume extr...


We’re Going Big On Industrial Fume Extraction

We recently announced the arrival at Axair HQ of the largest plastic fan we supply taken from the SEAT collection of corrosion resistant polypropylene fans. So we thought it was about time we spoke a little more about this powerful, energy saving yet quiet machine. It’s hard to ask for more from a fume extraction fan than the above qualities but the impressive SEAT S50 has all those attributes and more. Designed for exhausting fumes from hazardous manufacturing processes, the S50 and its smaller family member the S35 are the latest indust...
