Product focus: Oil mist separatot type OUPC

"The present high-efficient machine tools for metalworking are characterized by high processing speeds and thus the need for large volumes of cooling lubricants often added at high pressure.  Hereby large volumes of very fine particles/ oil mists occur that due to pressure and temperature ap-proaches the form of smoke.
This places greater demands on the choice of the oil mist separator, which is necessary for the cleanliness of venti-lation ducts as well as the compliance with external envi-ronmental demands. The finer particles require finer filters without it being on the expense of filter life/operating costs. – The oil mist separator type OUPC has been designed for exactly this purpose”

Mr. Brian Larsen - Sales Manager

The very compact oil mist sepa-rator type OUPC is designed with an efficient pre-separator, self-draining filter cartridge of the lastest glass fiber/polyester material and subsequently HEPA H13-filter.
