Test Chamber Extraction with Polypropylene Fans

feb march 19 10Test Chamber Extraction with Polypropylene Fans

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. (Read More)
Finding the long term resistance to corrosion for various types of materials requires the speeding up of corrosion up by using certain substances. For example, a salt spray testing chamber would recreate the effects of a harsh offshore environment to evaluate the corrosive properties of supplies, such as, paint coatings and phosphated surfaces. This will simulate the effects of years of exposure to salt spray. By testing in a chamber the variables can be controlled to ensure the measure of corrosion is as accurate as possible. Components are subjected to a corrosive environment without introducing other contaminants into the test area.

Chambers are often designed to test for compliance with standards. When components or surface finishes pass testing, they are considered compliant with corrosion resistance standards such as, MIL-STD-202H, BS EN 60068-2-52 or ASTM-B117.

As the environment in the chamber is designed to corrode metal or similar materials the extract system will also corrode if metal fans and metal ductwork are used. Axair offer polypropylene fans suitable for this type of application as they are resistant to corrosion. The fans are a single inlet centrifugal type complete with a pedestal for floor or wall mounting. Different materials are available for the pedestal construction, depending on the requirements of the setting.

To fine tune the required airflow rate and potentially save energy, Axair also offer inverters for fine speed control of the fan. The inverter can also have pre-selected speeds depending on requirements.
