Material
Polyamide based (PA) technopolymer.
- Cover: RAL 2004 orange, semi-matte finish, with graphic symbol 'valve'.
- Threaded connector: black colour, semi-matte finish.
Packing ring
NBR synthetic rubber.
Overpressure valve
Technopolymer with NBR synthetic rubber O-ring and stainless steel spring.
Set at around 0.350 bar.
Suction valve
Technopolymer sealing disk in NBR synthetic rubber and stainless steel spring.
Set at around 0.030 bar.
Air filter
Thermal-bonded polyester (FPE) filter with low pressure drop and high dust holding capacity.
Expected filtration class ISO 16890-1 ISO Rating coarse 75%, EN 779:2012 Class G4, air filtration 10 µ.
Maximum continuous working temperature
100°C.
Features
The use of SFW breather caps which create a pressure plenum chamber right above the oil level within tested limit conditions, in order to avoid any reservoir deformation, offers the following advantages:
- it reduces reservoir air volume intake keeping clean oil and filter;
- it improves suction pump action during working conditions reducing cavitation phenomenon;
- it prevents fluid leakage when the system is part of a mobile unit;
- it reduces foam in fluid.
Technical data
Air flow rate for the different executions of breather caps can be obtained from the diagram on the basis of the difference of air pressure inside and outside the reservoir.
Special executions on request
- Black colour cover.
- Overpressure valve set at 0.100 or 0.700 bar.
- Threaded connector also with NPT thread (National Taper Pipe Thread - ANSI-ASME B1-20, (SFW.70-3/4-NPT).
