Eaton’s FHF DGH21 signalling hooter range is designed for warning, calling, and indicating purposes in potentially explosive areas of group II and for rough ambient conditions.
The DGH21 housing is manufactured from glass-reinforced polyester (GPR) a durable and reliable material to prevent corrosion. The hooter uses a pressure-resistant installation and terminal compartment “increased safety” as an additional explosion-proof protection layer.
The signalling hooter 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 disconnector, which ensures a significantly longer life cycle compared to conventional solutions
