We have just delivered some custom designed high pressure filters for the Shell oil company in Nigeria. The application has required ratings of 600# and 900# and pressures of 100 and 140 bar g respectively. The filters have a quick opening system that has had to be adapted and designed expressly for the requirements, not being available as a standard product on the market. It is a key element for speeding up the change of the filter element, ideal for those processes where many particles accumulate and require a high cleaning frequency.
