Modern industrial processes have reached very high levels of sophistication and require compressed air systems characterised by higher air purity levels. Inadequate or low efficiency filtration can cause interruptions of service, high maintenance costs and loss of production. The PureTec F 40bar filters have been designed specifically to prevent these problems, offering guaranteed and laboratory tested filtration efficiency. The F 40bar filters are made up from a flanged carbon steel body containing a filtering element characterised by maximum nominal filtration (99.9%) and very low pressure drops.
