The rescue, using an air lance
to free the area around the girl, took around 20 minutes once the crews were on the scene on Sunday night.
Its compressor is rated at 300 cfm at 220 psi with an air lance
, and 300 cfm at 100 psi for air tools such as a jackhammer or a pneumatic tamper.
Compressed air for excavation is delivered through a proprietary air lance to penetrate, expand and displace all types of soil.
Its compressor is rated at 350 cfm producing 250 psi air through an air lance for excavation, and 100 psi to power accessory air tools.
The controlled atmosphere calciner is a natural gas, direct-fired, rotary unit whose effectiveness is enhanced by a unique method for introducing secondary combustion air via an air lance
The basic system includes Utiliscope's unique air lance
, making the VE-75 the world's most portable dry type vacuum excavator.
The Utilivac's standard hopper is a 75-gallon tank; optional larger tanks are available, in addition, the patented Air Lance
allows non-destructive excavation without high pressure water.
The truck-mounted air excavation unit has a vacuum rated at 1,000 cfm at 15 inches of mercury; for soft excavation, the unit delivers 300 cfm at 220 psi through the air lance
used for potholing.
Mounting repair air lances
oxygenation to the bottom;4.
Technicians clear surfaces and cracks of unwanted debris, unruly grass and excess moisture with blasts from hot air lances
delivering 2,800-degree heat before spraying on a professional-quality flat black sealcoat, more durable than that available in local home improvement stores.
In addition, air lances and blowoff devices are manually operated and exhaust high volumes of uncontrolled air.
As a result, manually controlled points of use, such as air lances, can have a profound effect on more sensitive equipment like robotic handlers or stackers.
