Air Starter Unit (ASU)

Home  >   Air Starter Unit (ASU)

100PPM / 120PPM / 180PPM / 250PPM / 400PPM & many more…

ASUs are used for starting aircraft engines equipped with pneumatic starter. It supplies necessary quantity of air at specified pressure through one/two or three hoses attached to the aircraft's under belly.

MAK design and manufacture ASUs from 100PPM to 400PPM (customized units can be made to order). MAK ASUs are under operation with major commercial airlines and military organizations across the globe. MAK has supplied custom designed ASU’s for endurance testing of world’s largest aircraft engine GE90-115B.

MAK ASUs come with a touch-screen control panel GSEM V8-A and MAK RDMS – A feature rich fleet management software which transmits live operational data to a remote computer/mobile and alerts users in real-time of faults, alerts. With this software users can plan maintenance schedules, ad-hoc service records, order spare parts… and much more.

Available in Towable Trailer mounted / Skid Mounted / Self propelled configurations
