Installed to reduce or remove contaminants from compressed air; water separators and filters are essential to the health and performance of a compressed air network. The primary function of any filter is to improve air quality, although modern demands mean this performance should not be at the expense of energy. Using high quality compressed air to supply the nitrogen generators, ensures long and trouble-free service and guarantees optimum performance.
The reliability of compressed air filtration is paramount to the ongoing fight against problems caused through contamination entering the air system. Contamination in the form of dirt, oil and water can lead to:
The Gardner Denver filter range provides clean, high-quality air as defined by ISO 8573.1:2010 and are certified by a third party under ISO 12500-1.
When designing a compressed air system it is common practice to avoid unnecessary changes in pipe size and air flow direction. Each of these can have significant and adverse effects on the amount of differential pressure created leading to increased energy required by the compressor in order to provide the correct air pressure at its point of use. Gardner Denver filters employ several design features which ensure that this best practice philosophy is carried on through our filter and water separator housings to maximise energy savings caused by differential pressure.
The benefit of energy saving without compromised performance is achieved through a number of unique and patented design features which minimise differential pressure. The Gardner Denver compressed air filter range combines the filter housing and element to work together in maximising energy savings and provide low lifetime costs without compromising on air quality and covers a large range of filtration grades to match the applications air quality needs.
Superior Filtration Technology
Annual service is easy and clean to carry out thanks to and easy to grip housing bowl and no need for the user to directly handle the contaminated element. The pressure drop indicator monitors the efficiency of the filter and indicates when pressure drop is getting too high and element replacement is recommended.
The GDWS range of water separators provide bulk condensed water and liquid oil removal and are used to protect coalescing filters against bulk liquid contamination. 0.5 – 200 m³/min* Up to 80°C
For higher temperatures, the filters are available in the standard grades to cover dust, general purpose and high efficiency filtration. 0.5 – 516 m³/min* Up to 150°C Peak: up to 210°C
The GDF Series of filters efficiently removes water and oil aerosols, atmospheric dirt and solid particles, rust, pipescale and micro-organisms.
