Leading Manufacturer of Degreasing Machinery and Equipment

Aerospace component cleaning and degreasing


Rotajet manufacture a range of spray washing machines, used for degreasing and cleaning aerospace components and parts for both new manufacture and MRO facilities.

Aerospace Component Cleaning and Degreasing


Rotajet manufacture spray washing and degreasing equipment for a large number of applications in the aerospace industry, from new parts manufacture to overhaul. Below is a brief outline of the various applications for Rotajet range of parts washers:-

New parts degreasing:

Rotajet machine small cell parts washing machines for small component degreasing, for large components, Rotajet manufacture the D series of front loading spray washing machines, these degreasing machines are ideally suited to washing and degreasing larger aerospace components, two stage wash and rinse machines are typically used, to avoid any staining on the machined surfaces Rotajet can also fit a additional fresh water purge. The wash solutions can be monitored using pH or conductivity, and all readings data logged for traceability. Rotajet will supply the machines with a suitable aerospace approved degreasing chemical along with all test and control methods for the wash solution.

If the components are too large for the standard Rotajet degreasing machine, Rotajet can manufacture bespoke machines to accommodate the larger sizes.

New parts crack detection:

The Rotajet D serie front loading spray washers machines are typically used for degreasing and washing aerospace components prior to dye penetration crack detection. The washing machines are fitted with four stages, wash, rinse, fresh water rinse and dry. In areas were the water is hard and contains high levels of calcium salts, the final rinse is normally passed through ion exchange resins to reduce the dissolved salt levels in the rinse water. In NDT application the machines are fitted with water monitoring and data logging features.

For larger components which the Rotajet D series of washing and degreasing machines will not accommodate, Rotajet manufacture bespoke machines.

Overhaul MRO:

Prior to any repair or maintenance the components need to clean and free from any surface contamination. Rotajet manufacture a range of spray washing and ultrasonic cleaning equipment for removal of surface coatings, carbon deposit, paint, etc….

The standard range of Rotajet parts washers are typically used for the initial cleaning and removal of heavy deposit of oil, grease, dirt etc…from the components prior to stripping down. Once initially wash and degreased in the Rotajet parts washers, the parts are stripped into individual component parts, these are then washed and degreased again prior to inspection.  The operation may be performed in spray washing machines or a combination of spray washers and ultrasonic cleaners, depending on the component being maintained.

If components will not fit into standard Rotajet spray washing and ultrasonic cleaning machines, bespoke machines can be manufactured.

Rotajet will supply the machines with a suitable aerospace approved degreasing chemicals along with all test and control methods for the wash solution.
