MK17 BALANCED DIAPHRAGM FIRST STAGE
The Icebreaker. Our highest performance diaphragm first stage regulator designed for harsh environments and for the use in cold water or contaminated environments. It is equally popular in all other environments with demanding and selective divers who appreciate smooth air delivery and maximum breathing performance in the diaphragm category.

DESIGN & PERFORMANCE
Balanced diaphragm design. Cold water dives often require special equipment, generate a high consumption of air and require a prompt delivery of air. The over balanced design meets these requirements and provides an instant and constant high performance at all tank pressures.

Dry ambient chamber. The diaphragm design prevents the entry of water into the first stage mechanism and enhances a trouble free operation even in the coldest conditions.

ENVIRONMENT & ADJUSTMENTS
Thermal Insulating System (TIS) and Anti Freeze (AF) System. An additional safety feature to the insulated first stage mechanism in real cold water. Both systems protect inner parts through ice repellent coatings and accelerate heat transfer. The result: even the stringent CE requirements for cold water are exceeded.
COMFORT
Compact Design. Remarkable low weight and volume compared with other conventional diaphragm stages.
4 low pressure ports (2 HFP)
