AIR DRIVEN LAMP

Explosion-Proof Compressed Air / Electric Safety Light  – 330621-330638

IMPA CODE: 330621-330638

Explosion-proof pneumatic light for cleaning operations of tanker holds, etc. where hazardous gases may exist. Compressed air drives the generator which is directly connected to a turbine, and further enters the switch chamber which causes the lamp to light by activating a differential pressure switch.

Products characteristic

The product could work under the Ambient temperature from -20°C to +50°C, It is apply to explosion gas area (Zone 1 and Zone 2) and explosion dust area (Zone 21and Zone 22), apply to gas area of IIA、 IIB、II C class. Temperature classification is from T1 to T6.

Due to its special construction an ignition of hazardous atmospheres inside and outside the lamp are avoided by several solutions. At first the air flows into the lamp housing and generates an overpressure before it flows into the generator housing. 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.

The lamp-housing is made of brass or aluminum.
