Filter performance depends on more than the element. The filter head provides the interface with the system, making its design, casting quality, and fitment essential to a reliable filtration assembly.
Ashra combines filtration system expertise with custom filtration design for oil filters and cast filter heads. High-quality castings are produced through gravity and pressure die-casting, with completed heads available for testing in Ashra’s laboratories.

Ashra can design and manufacture oil filters and cast filter heads around defined application and fitment requirements.
Gravity and pressure die-casting allows the production method to be matched to the design, material and volume requirements.

Casting partners manufacture components based on Ashra-specified designs, supporting control over fitment and application requirements.
Laboratory testing can support quality control in filtration component development. Required test methods and acceptance criteria are agreed upon for each application.
Projects can begin with a physical sample, part number or a new application requirement.

Air-oil separator filters for Cummins
Air-oil separator elements exploit the phenomenon of coalescence, using micro-glass fibre layers to remove droplets of oil from the compressed air. This filtration process is effective right down to the sub-micron range, to keep oil consumption and oil entrainment into the compressed air networks to a minimum.
FAQs on filter heads and accessories
An oil filter head provides the interface between the filter and the equipment. It supports mounting and directs oil into and out of the filter assembly through the required connections.
