Wheelock WH-DB1HPULA Explosion Proof Horn Grey 110 VAC


Our Price : $2,902.00

Product Code: WH-DB1HPULA


This range of light weight, flameproof horns has been designed with a high weatherproof rating to cope with the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries. New electronic circuitry allows the DB1P and DB1HP to be switched between two selectable tones by either reversing the supply polarity, or connecting a second voltage supply. The higher output DB1 HP is particularly suitable for noisy environments.
