Product Information

The Wolf Airturbo lamp is the longest established Wolf product still in manufacture today, although it has been upgraded many times over the years. Originally used in the Coal Mining Industry to meet the rigorous requirements of underground explosion proof lighting, it is now BASEEFA certified for use in zones 1 and 2 industrial hazardous areas. Today applications are in the Oil and Petrochemicals Industries, for tank cleaning and pipeline inspections, offering a safer alternative to low voltage lighting in dangerously wet conditions or in flammable gases and vapours. Once connected to a suitable air supply, continuous output of high quality general illumination is produced, even under water.

Airturbo Lamp A-0444 is fitted with a Bay Light type head to the generator providing all round illumination when the lamp is suspended above the work area. The moulded ball glass containing the bulb is surrounded by a protective polycarbonate dome.

Airturbo Lamp A-0445 provides a flood beam giving a well diffused 30° angle of light with the standard matt reflector, or with a polished reflector, a highly concentrated spot light. The lamp has a 15 mm toughened glass lens for high impact strength and pressure resistance.

The lamp 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. A gun metal 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, but if needed, suitable air-line filters can be supplied with the lamps. Another mandatory requirement of safe use is anti-static hose, designed to avoid a dangerous build up of static electricity.

The Airturbo lamp has many inherent safety features recognised in the BASEEFA Approval; an effectively pressurised and purged system, a 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.

All the lamps are run in, tested and set to the necessary output prior to despatch, full maintenance instructions and lock keys are supplied with every Airturbo unit. In-house training on the maintenance and repair of air lamps is available

Accessories

The Airturbo and Turbolite lighting systems are very flexible and can be adapted to all sorts of confined space applications varying from huge storage tanks to small sewers.

The Lamps can be suspended from bracing or spars, sited on platforms or mounted on tripod stands to illuminate the entry and working area as effectively as possible.

As previously emphasised, there are two important conditions of Certification which must be observed in any installation:

1. The supply hose must be of an Approved Anti-Static Type such that the electrical resistance between couplings must be within the limits of 10⁴ohms (Min.) and 10⁸ohms (Max.)

2. The compressed air supply should be clean, dry and uncontaminated.

Folding Tripod Stand A-300
This very strong and convenient tripod stand is available for mounting airlamps in such a way that illumination can be angled in most directions. The lamp can be clamped to the tripod head without the need of any tools. When not in use the tripod can be folded away for easy storage.

Anti-Static Compressed Air Hose (A-179 and A-180)
This special 12mm bore single braid hose is manufactured from an anti-static compound and is available in 18.3 metre (A-179) or 36.6 metre (A-180) lengths. Stainless Steel Hose Clips are provided but air line couplings are not for reasons of possible incompatibility.

Air Line Filters
A simple automatic drain airline filter (A-184) can be supplied, but where there are major difficulties in achieving the air quality required an ultra high efficiency filter system (A-186) is recommended, and, as with the simple filter, has the throughput capacity sufficient to power either two Turbolites or six Airturbo Lamps.

Tools and Spares
All of these items are available off the shelf and in special circumstances can be express shipped the same day in order to meet an urgent demand.

Repairs
The Company offers a repair and refurbishment service for all its compressed air safety lamp products with the aim of completing these tasks within 7 days of receiving confirmation instructions. Repair instructions and procedures are written in accordance with ISO 9000 Standards
