"Energy costs are on the rise - Take control with a waste oil fired heater package from Lanair. Waste oil not only eliminates the cost to haul used oil off-site, but it can reduce your heating bills too. In addition, burning waste oil to get 'free' heat deals with a major pollution problem in an environmentally friendly way. Complete package is designed for commercial use. Advanced atomization technology with monthly maintenance eliminates the tedious daily cleaning required by old vaporization technology.
