AirBurst® equipment is manufactured and suppurled by a USA company, parts are available in Texas, USA. The Air -Shock equipment is lsmeli, (also known as B(weBlast 11) 2. The first use of the AirBurst process was February of 1995, Air -Shock was first used in the USA in approximately 2003. 3. The AirBurst air gun is easily repairable in the field without the use of exotic tools; repair parts are readily available in the USA. 4. Patented air gums used in the AirBurst process are ilia nutaclured by a USA company, Teledyne Marine Corporation that has over 50 years of experience and owns numerous related patents. The air buns are specifically designed for hostile environment use in water wells and were never designed to clean silos.. 5. Several Bolt air guns are capable of � untinuous operation up to 3000 psi, AirBurst air gun discharge ports are configured to produce a single bubble for efficient mass displacement of the water produced by the i expanding Itiubble; it Is not just a ncurrow slot and jetting action as depicted by the Air -Shock literature. Creation of the hubhlk� and subsequent collapse creates a negative pressure which withdraws dislodged material through the screen or out of a rock ti-acture. 6. The Iitning between energy discharges is critical as energy bursts too close together do not allow for dislodged debris to settle before the succeeding burst occurs. AirBurst is the only process [hat cku3 electronictilly regulate the timing and allow the debris to exit the path of the next cnergy discharge, thereby reducing the amount of debris that is pushed back into the formation. 7. The Bolt au• gun is operated by a solenoid valve integral with the air gun which allows complete surface control of the duwn halt; energy discharge li•om the air gun and critical shuttle opening and closing timing which is of paramount importance especially at great depths and in extremely abrasive environments. The Air - Shook device has no such control and is operated by a preset pressure adjustment made prior to lowering the device into the well. When the preset pressure is reached the air gun fires, the unchecked timing results in a very rapid energy release every one half to three seconds and is controlled by inl ei Iou Ily changing an orifice. Air -Shook has no slttkttle timing; control and requires removal from the well to make pressure adjustments, resulting in a lot ofwasteti time. 8. The discharge ports of the Bolt Deep bole Service air gun are closed at all times except For the actual energy discharge. This keeps abrasive well debris out of the shuttle opening. which enhances dependability and greatly extends operational life of the air gun.
