Taughannock Aviation's oxygen and nitrogen boosters are built to make your low-pressure bottles useful down to 250 psi while boosting to higher specified pressures. This allows greater utilization of low-pressure bottles, thus lowering the number of cylinders kept in inventory and significantly decreasing the amount of wasted oxygen and nitrogen. The boosters are compact, user friendly, save time and money, and automatically shut off at desired set pressure. For more information call (607) 257-1666 or visit www.flytac.com.
