Filters and Separators
Optimum performance & efficiency
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.
Key Benefits
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:
- Pipescale and corrosion within pressure vessels
- Damage to production equipment, air motors, air tools, valves and cylinders
- Premature and unplanned desiccant replacement for adsorption dryers
- Spoiled product
- The Gardner Denver filtration range offers various products and grades of filtration to provide peace of mind whatever the air quality requirement. It has been designed with focus on reliability and efficiency
The standard for high-quality air
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.
Low differential pressure = Low energy consumption
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.GDWS Condensate Separators
- For the removal of bulk condensed water and liquid oil
- Used to protect coalescing filters from bulk liquid contamination
- High liquid removal efficiencies at all flow conditions
- Tested in accordance with ISO8573-9
GDFT Oil Vapour Removal Filter
“Technically Oil Free Air” from Oil Lubricated & Oil Free Compressors
- Air Quality Guarantee
- Suitable for use with oil lubricated and oil free compressors
- ISO8573-1 Class 1 for total oil delivered air quality
Tested in accordance with ISO8573-5 and 3rd party performance validated by a third party
GDFT is matched to all inlet parameters maintaining effective operation for 12 months. Correct sizing ensures seasonal variations in temperature do not affect delivered air quality
GDFT provides “Technically Oil Free Air” when used in conjunction with water separators and coalescing filters
Design
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 combine filter housing and element to work together in maximising energy savings and provide low lifetime costs without compromising on air quality. Large range of filtration grades to match the applications air quality needs.
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.
GDWS Series - Energy efficient by design
- Wet air enters the inlet port and is directed into the separator module fixed turning vanes causing the air to spin inside the vessel and then change direction as it passes the impinger.
- A vortex is then created which narrows and intensifies as it reaches the lower part of the separator.
- Bulk liquid is therefore removed from the air stream due to a combination of: - Directional changes of the air stream. - Velocity changes. - Centrifugal action of the vortex.
- As the vortex reaches the bottom of the separator module, air is forced through the centre of the vortex.
- Aerospace turning vanes located in the outlet of the separator module now turn an “inefficient corner” into a number of more “efficient corners” to reduce turbulence, minimise pressure loss and therefore operational costs.
When compressed air is required to meet ISO8573-1 Class 1 air quality via oil free or oil lubricated compressors the GDFT Oil Vapour Removal filter is an essential component of the compressed air system.
GDFT Oil Vapour Removal filters are designed to reduce oil vapour and also overcome the issues of traditional loose filled carbon towers.
Manufactured from extruded aluminium, the GDFT is smaller and lighter than equivalent carbon towers. Compact activated carbon cartridges utilise a unique filling technique to maximise packing density of the adsorbent bed. Retained to prevent movement, 100% of the activated carbon bed is then utilised during operation, guaranteeing performance, whilst the heavy attrition, dusting and blocked particulate filters associated with carbon tower designs is eliminated.
The use of cartridges also provides trouble free maintenance, reducing system downtime.
