MP Filtri LMD 400-401 431 Low & Medium Pressure Filters


MP Filtri LMD 400 series filters have a working pressure of up to 16 bar and flow rates of up to 590 litres/minute.

LMD 400 filters are versatile, low pressure duplex filters with an integrated changeover function – allowing the filter element to be replaced without shutting the system down. They are therefore particularly suitable for systems where shut-down causes high costs or safety issues.
