FHF dGW21 Explosionproof Alarm Bell Range

Eaton’s FHF dGW21 alarm bell range is designed for signaling purposes in potentially explosive areas of zones 1 and 2.

The dGW21 housing is manufactured from glass-reinforced polyester (GPR), a durable and reliable material to prevent corrosion. The alarm bell meets weatherproof type 4X/ 1P66 environmental ratings and provides ultimate protection.

The alarm bell produces a sound level of approx. 105 dB(A) at 1-meter distance and is available for all common supply voltages. All DC variants are equipped with an electronic contact breaker, which ensures a significantly longer life cycle compared to other solutions.
