PNEUMATIC AIRLAMPS with fluorescent lamp - zone 1

(new lamps will not be offered and supplied, only repairservice is available)

Using SBE - pneumatic airlamps in hazardous areas is very safe mode of illumination.

example of use    

The lamps type sPL 63020 and sPL 63040 are used in workstation without an stationary powersupply. The lamps work with a low air consumption. 
- tunneling works
- tank - ships
- canalisation
- boiler plants 
The lamps can be used in all hazardous areas zone 1. 




Due to its special construction an ignition of hazardous atmospheres inside and outside the lamp are avoided by several means. At first the air flows into the lamp housing and generates an overpressure before it flows into the generator housing to drive the turbine wheel of the AC-generator to induce the voltage for the bulb.
If the lamp housing or the protection glass is damaged, the air flows outside first. The generator stops immediately and cannot induce any voltage for the bulb.
The exhausting air prevents a penetration of explosive gases inside the lamp and can cool the spiral of a broken bulb, too.

Pressure-fluctuations of the air are compensated by the air regulating system inside the lamp. The lamp-housing is made of brass.  .
