Product Description

In-Line Duplex Industrial Filter (FMND Series 3000 PSI)

The HYDAC FMND Series high-pressure in-line duplex filter provides continuous, reliable filtration for demanding hydraulic systems. Rated up to 3,000 psi with flow rates up to 100 gpm, it features a built-in changeover valve, optional bypass protection and clogging indicators for efficient operation and maintenance.

Features:

• The FMND filter consists of a ductile iron filter head with built-in changeover valve and three different lengths of screw-in filter
bowls.
• The FMND filter can be supplied with or without bypass valve, (located in head assembly) but includes vent and drain screws,
and also a connection for a differential pressure clogging indicator.
• Pressure equalization requirement is achieved by raising the changeover lever prior to switching it to the relevant filter side.
• Fatigue pressure rating = maximum allowable working pressure rating.
• Germanischer Lloyd (GL) approved
• This filter can be modified to meet the requirements of DIN 24550* as follows:
– Filter size 0160 with G 1-1/4” port selection
– Filter size 0250 with G 1-1/2” port selection
– Filter size 0400 with SAE-DN 38 1-1/2” Flange
*Note – SO882 design does not meet DIN 24550.
