LA*B Hot Air Lance in operation - cracksealing preparation done the right way.

This is the LAB Hot Air Lance in full operation cleaning and drying pavement joints in concrete prior to the application of a hot applied joint sealant. This video shows the unit running off a 100 cfm compressor. Notice the unit does not use any external flame, the units produces high velocity concentrated hot air. Unit may also be used on asphalt. Much faster and effective than any other "heat lance" on the market.
