Suction line filters 95 l/min universal hydraulic filters for the suction line
Suction line filters with flow up to 95 l/min (complete Spin-On canister filters of the AMF 301 MN series and replaceable suction elements from brands like AHC, Sofima, and Hydrolider) are professional filtration devices designed for continuous protection of hydraulic pumps against solid contaminants. Mounted on the suction line between the oil tank and the main pump inlet port or directly on the tank wall, they constitute an irreplaceable barrier preventing metal shavings, sand, scale, and deposits from entering the power system. This category includes complete filters, heads, and replaceable canister elements adapted to work at operating pressures up to 12 bar and a nominal flow of 95 l/min (for oil with a viscosity of 30 cSt / class HL 30). The integrated bypass valve with a low opening threshold of 0.3 bar protects the hydraulic pump against cavitation and dry running during cold starts and with increasing resistance on the filter element. 95 l/min suction line filters are a proven solution used in agricultural, construction, forestry machines, and stationary industrial power units.
Application and technical characteristics of suction line filters 95 l/min
Hydraulic suction filters with a capacity of 95 l/min are widely used in power hydraulics circuits with medium flow rates of the working fluid. Their task is to thoroughly filter the oil drawn from the main tank, which prevents accelerated wear of gears, pistons, and seals in the pump.
- Nominal flow up to 95 l/min: Ensures free oil flow to the pump without creating dangerous vacuum on the suction side.
- Standard filtration accuracy (125 µm): The filter mesh effectively retains mechanical particles without causing excessive flow resistance.
- Suction bypass valve (0.3 bar): Low opening pressure of the emergency bypass protects the pump from interruption of oil supply and the destructive phenomenon of cavitation.
- 1 1/4" BSP threaded connections: Standardized female threads (G 1 1/4") in aluminum and steel guarantee high safety and tightness of installation.
- Fast Spin-On canister service: A screw-on metal housing (e.g., AMF 301 MN AHC or Sofima) allows for efficient and tool-free replacement of worn-out consumables.
Why choose suction line filters 95 l/min at the HYDRON store?
The suction line filters from the AMF 301 MN series offered by the HYDRON store are manufactured according to strict ISO 9001\. They are characterized by high resistance to housing burst pressures up to 25 bar and full compatibility with standard mineral and synthetic oils. Remember that conditions in the suction circuit are extremely sensitive to changes in temperature and fluid viscosity. For this reason, engineers recommend choosing a suction filter with a flow capacity margin of 30–40% relative to the supply pump output. This prevents the bypass valve from opening during startup on cold oil. For comprehensive construction and service of the power system, we recommend selecting other compatible products from our offer, such as efficient hydraulic pumps, flexible hydraulic suction hoses, supplementary return line filters and durable hydraulic directional control valves.

Frequently Asked Questions (FAQ)
Where is the 95 l/min suction line filter installed?
The 95 l/min suction line filter is installed on the inlet line before the hydraulic pump or screwed directly to the oil tank wall.
Why does the bypass in a suction filter open at 0.3 bar?
The bypass valve has a very low opening threshold of 0.3 bar to immediately clear the oil supply in case of fluid thickening or element clogging, protecting the pump from harmful cavitation.
How does the AMF 301 MN suction filter differ from the AMF 301 CV return filter?
The AMF 301 MN series (suction) has a 125 µm micron rating element and a 0.3 bar bypass valve. The AMF 301 CV series (return) has a 25 µm micron rating element and a 1.7 bar bypass valve.
How often should the element in a 95 l/min suction filter be replaced?
The filter element should be replaced periodically during machine inspections (usually every 500–1000 operating hours) or at least once a year before the winter season.
