The Airturbo, originally used to meet the rigorous requirements of underground explosion-proof lighting
for coal mines, is BASEEFA certified for use in Zones 1 and 2 industrial hazardous areas, typically in oil and
petrochemicals industries for tank cleaning and pipeline inspections. Once connected to a suitable air supply,
continuous output of high-quality general illumination is produced, even under water. The A-0444 is fitted
with a bay light type head providing all-round illumination when suspended in the work area and a protective
polycarbonate dome surrounds the molded ball glass containing the bulb. Housings are spark-free cast brass
with a forged brass safety hook, all nickel-plated. The generator is a compressed air-driven turbo-alternator
of simple design and robust construction and a gunmetal impulse turbine wheel produces the energy to
power the 12v 55w Tungsten Halogen bulb. A clean dry air supply is a condition of certification and
essential for the efficient running of these lamps. Deposits of dirt on the inside of the lens will adversely
affect the level of illumination and if needed, air-line filters can be supplied. Another mandatory requirement
of safe use is an anti-static hose, designed to avoid a dangerous build-up of static electricity. The Air turbo
has many inherent safety features, recognized by BASEEFA; effectively pressurized and purged system,
protective curtain of air from the exhaust ports, instant cut-off of the lamp if the lens is broken, and cooling
of heat generating components. Lamps are routinely run in, tested, and set to the necessary output prior to dispatch.
