The HBP Desiccant Breather has been specially designed to provide an economical
protection device for smaller transformers having a low oil content. The Breather
body and oil seal cup are moulded in high strength polycarbonate, which offers
mechanical strength and weather resistance, the transparent material also allows
all round visability of the Desiccant at a distance.
The design of the HBP Desiccant Breather allows the capacity to be increased
for use on larger transformers. This is known as the HBP/2.
Hawke Desiccant Breather types HBP and HBP/2 are refillable.
