9788 Super Duty Bypass Filter Unit

The 9788 Super Duty Bypass Filter is the largest of the FA-ST Engine Bypass Filters: H17.15cm x D22.23cm The unit is ideal for engines with a sump of up to 85 litres and will remove 0.98 litres of water per filter cartridge as well as 2.5Kg of particulate contaminate.

The 9788 housing is for use with large engines, heavy industrial & plant machinery. Suitable for all types of engine oils and can also be used on diesel fuel and light hydraulic oil up to 46 viscosities.

• Flow Rate: Output levels are dependent on the viscosity, temperature, and degree of contamination and oil pressure. (Guide for SAE 15W40 oil at 158 degrees F and 60psi, the flow rate would be approx 4 to 7 litres per minute)
• Operating Temperatures: Within operating specifications of engine, gear, and hydraulic oils.
• Operating Pressures: Maximum rating of 10 bar. Lid torque is 23 lbs/foot

Replacement Filter Cartridges for 9788:

• 1888H Filter Cartridge: with dirt retention capacity of approx. max 2Kg solid particles and approximately max 980 ml water. These are the standard FA-ST filter cartridges supplied with all units unless requested otherwise. These cartridges come supplied as single filters or boxed quantity of 6.
• 1888SPT Filter Cartridge: with dirt retention capacity of approx. max 2Kg solid particles and approximately max 980 ml water. These cartridges are made of two layers of filter media with a 1-micron layer in the middles. These filter cartridges are ideal for polishing light oils and diesel fuels. These cartridges come supplied as single filters or boxed quantity of 6.
• 1888SH Filter Cartridge: with dirt retention capacity of approx. max 2.5Kg solid particles and approximately max 980 ml water. These filters are designed for systems using high viscosity oils from 320 to 460 viscosity, as an amount of oil can bypass the filter. This allows for filtration of higher viscosity oils however due to the bypass effect will require more passes to remove contaminates. These cartridges come supplied as single filters or boxed quantity of 6.
• 2088PP Filter Cartridge: For filtering emulsified fluids & water glycol, these filters allow water to pass through however will still entrap dirt in the filter. These filters are made from a 5-micron Polypropylene filter media with a 1-micron filter base layer. This filter cartridge DOES NOT absorb water but has a dirt retention capability like the 1888H filter cartridge. These cartridges come supplied as single filters or boxed quantity of 6.
• 2088PP6 Filter Cartridge: For filtering emulsified fluids & water glycol, these filters allow water to pass through however will still entrap dirt in the filter. These filters are made from a 5-micron Polypropylene filter media with 6 x 1-micron filter base layer for increased filtration. This filter cartridge DOES NOT absorb water but has a dirt retention capability like the 1888H filter cartridge. These cartridges come supplied as single filters or boxed quantity of 6.
• 2088CPS Filter Cartridge: These are mainly for high viscosity oils as they are 50% polypropylene on the top, with 50% cellulose on the base this reduces the amount of back pressure on the filter and allows the higher viscosity oils to pass through the dense media.(retention is 50% of 1888H). These cartridges come supplied as single filters or boxed quantity of 6.

All boxes and individual cartridges contain spare lid seals for filter housings. Cartridges filter fineness of 1μm nom, 3μm absolute. Temperature operating range 0-135°C, +/- 5°C. The stated volumes of oil are only relative to installation of single filter housing. All cartridges are protected by a nylon outer cover with pressed brass ring holder.

On installation the BRASS RINGS MUST BE FACING UPWARDS

Filtration Level: Particulate contamination in accordance with BS 5540 part 4: 1981 and ISO/DIS 4406. ISO 14/9 equivalent to NAS 1638 class 6 - hydraulic oil specification.
