The NEW BlastBagTM Aero from MTi is the first of its kind. Designed with underground applications in mind, the BlastBag plug is the most versatile product type on the market. Consisting of an airtight bladder system, a resilient outer protective coating (also clearly displays all relevant information about use and safety) and a high flow quick-connect coupling, the BlastBag Aero is as easy to use as it is reliable. The dual bladder construction and positive valve sealing mechanism ensure that leakage doesn’t occur when shots are left to sleep. The NEW valve incorporates a Schrader valve for reliability and an annular snap coupling for fast and easy connection. This patented valve arrangement connects to a durable Stainless Steel coupling, which is interchangeable with other MTi products such as the HoleSave plug and the BlastBall plug. Improve fragmentation, obtain a SAFER final wall, dig easier, eliminate explosive wastage, control void management, block off breakthroughs quickly and effectively, protect drilled holes and utilise the charge through function for underground upholes are just a few applications where the BlastBag Aero can be used with excellent results.
