Extraction from Test Chambers

Test chambers are designed to examine various types of materials in many different ways for a wide scope of applications. Chambers may be required to measure corrosion or to test components to destruction. Their primary function is to speed up the processes to simulate time in an environment with certain characteristics. Finding the long term resistance to corrosion of materials requires the speeding up of corrosion by using certain substances. For example, a salt spray testing chamber would recreate the effects of a harsh offshore environme...


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 ...


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...


Corrosion Resistant Fans – An Axair Guide

Plastic fans have come a long way from their origins as a somewhat  ‘home made’ product. The principal manufacturers, including our partner, SEAT Ventilation, are now offering powerful, low noise, low vibration products with very good mechanical isolation. Here, we offer an overview of the key principles and benefits of plastic centrifugal fans. Application Laboratory fume cupboards are by far the most popular application for corrosion resistant plastic fans. There are several other important applications such as the ventilation of fumes ...


Steel covers for fan filter units

Designed for use with the “FPF”, “FF” and “GF” series, stainless steel covers provide protection against direct hosed water and foreign objects. They are particularly suitable for outdoor use and within the food industry. With easily removable and washable covers they make the unit completely weatherproof providing protection against rain, snow, direct sunlight or vandalism which normal plastic may be vulnerable to. The thermal management accessory with a stainless steel construction and a permanent gasket included, they are...
