Description
High Pressure Filters
- Type: In-line
- Maximum operating pressure: Up to 42 MPa (420 bar)
- Flow rate: Up to 250 l/min
The FMM is a versatile high-pressure filter series designed to protect sensitive components in high-pressure hydraulic systems, especially in mobile machinery. These filters connect directly to the system lines through hydraulic connections.
Available Features:
- Female threaded connections: Up to 1 1/4", maximum flow rate 250 l/min.
- Fine filtration rating: To improve system cleanliness level.
- Bypass valve: To relieve excessive pressure drop across the filter medium.
- Low collapse filter element "N": For use with filters equipped with a bypass valve.
- Low collapse filter element with external support "R": To protect the filter element from back pressure caused by the check valve in filters with a bypass valve.
- High collapse filter element with external support "S": To protect the filter element from back pressure caused by the check valve in filters without a bypass valve.
- Visual, electrical, and electronic differential clogging indicators.
General Applications:
- Agricultural machinery
- Mobile machinery
