LAB Heat Lances burn vapor propane and mix it with super heated compressed air in a specially designed and pantented combustion chamber. High velocity hot air is produced and directed towards the pavement surface. Since no flame touches the pavement, you can fill cracks immediately behind the lance operator without the worry of burning or charring the pavement surface.
Unlike other lances or torches, LAB Hot Air Lances dry and clean surfaces without an exit flame. The flame is completely retained within the heating head, jetting hot compressed air only. Surfaces prone to oxidation are easily softened and removed, leaving an impingement free area.
High temperature hot air insures sealant adheasion with fast, efficient drying in one easy step. Our lances are precision engineered and outperform all imitators. The units light easily and can be operated with only a few minutes of training.

FACTS
* Crack sealants will not stick to wet and dirty asphalt or concrete pavements.
* Cleaning, drying and heating the pavement crack improves the adhesion of crack sealants.
* The Strategic Highway Research Program (SHRP) recommends treating cracks with a Hot Air Lance prior to sealant installation.
* A clean, dry crack is your first step to ensuring successful crack repair. LAB Hot Air Lances can help you achieve this goal by blowing out and drying moisture and debris in pavement cracks in one quick step.
BENEFITS
* Maximizes the adhesion of any crack sealant.
* Will increase productivity and decrease job delays by allowing crews to work after a recent rainfall, dew or cold temperatures.
* Eliminates other costly preparation tools, routers, blowers, wire brush crevice machines.
* Easy to operate and maneuver, lightweight yet durable.
* Constructed with high strength steel and stainless steel tubing.
* Precision engineered to exacting standards for safe reliable operation.
* Adjustable temperature and air volume controls.
* Patented combustion system.
* Cracks are cleaned at operators walking pace.
* Built with pride in the USA.
