Not only do FunnelCaps prevent FOD in turbine oil, FunnelCaps are also better for the environment.
Most smaller turbine engines only require a small amount of oil top up. TheCanKey FOD free oil servicing tools are perfect for this and allows you to keep left-over oil for next top up.
The FunnelCaps creates a sealed FOD free environment once installed on the oil can. After servicing leave the FunnelCap installed, even on the empty oil can. This ensures no contamination of the FunnelCap and also shows which type of oil residue is in the FunnelCap, so you don’t mix oils.
Use TheCanKey FunnelCaps to avoid:
- spilling into the nacelle by back- or over‑owing ordinary funnels.
- getting oil on your hands or clothes.
- throwing away left-over oil.
- FOD in open oil cans.
- mixing oils.
To prevent contamination of aviation turbine oils, it is important to use clean, dedicated equipment and to properly clean and maintain all equipment and containers used for oil. Oil storage places should be kept clean and free of dust and debris, and all equipment and containers should be cleaned and inspected regularly.
In other words, clean the oil cans in the warehouse and seal them with TheCanKey DustCap. This keeps the oil can clean, even in a dirty environment. Remove the DustCap and use a FOD free TheCanKey oil can opener to open the oil can and right away install a FunnelCap for servicing the oil to the turbine engine.
