Clarcor offers high performing E12 rated filter protection for gas turbines from salt and water in all conditions.
Specifically developed for offshore conditions, the Static Offshore vCell filter is designed for extended periods of operation while offering maximum protection against corrosion and fouling for reliable turbine operation without the risk of sudden pressure spikes.
The altair Static Offshore Filter EPA System uses glass fibre media which has a deep filtration layer that handles moisture and hydrocarbons much better than filters that use technology such as ePTFE membranes.
Salt is one of the most damaging threats to gas turbine reliability and, as it is hygroscopic (an affinity for water and absorbs moisture from surrounding air) in nature, can attack a turbine both in particulate and liquid form. This makes it particularly difficult to handle and means that, alongside capturing fine particles, the filtration system must also efficiently handle moisture.
As well as salt being carried through to the turbine in its liquid phase, moisture left in the inlet air stream will combine with dust to form mud which can block a filter.
ePTFE membranes use a single, thin layer of high efficiency media which can quickly become blocked by moisture droplets. Glass fibre media, however, is around ten times thicker and its greater pore volume makes it naturally less prone to sudden blockage. This means that high efficiency filtration can be achieved without the risk of downtime caused by sudden pressure spikes and with much longer running periods between maintenance intervals.
