Salvage Bureau Heavy Diving Helmet Surface-Supplied Diving Equipment

The diving helmet is made of glass fiber material, featuring lightweight, sturdiness, crack resistance, impact resistance, and non-conductivity. The rigid helmet body serves both as a framework for mounting various components and as a head protector. The left, right, and rear counterweights of the helmet body offset its buoyancy in water, providing the diver with a well-balanced feeling underwater.

The diving mask offers advantages such as safety and reliability, sensitive air supply adjustment, comfortable breathing, comfortable wear, clear communication, a wide field of view, and ease of movement underwater, making it an ideal diving apparatus for underwater operations.
The diving equipment has a wide range of applications, suitable for conventional diving and saturation diving using air and mixed gases. It can be used for underwater cutting, welding, filming, inspection, salvage, aquaculture, and other underwater operations.
The diving equipment can be used in conjunction with dry suits, wet suits, or hot water suits as needed, or used independently, adopting a mask-style structure.
The diving equipment is supplied with air via an umbilical or self-contained air cylinders.

Product Parameters:
Operating Depth: 300m
Supply Air Overpressure: 0.6-1.4MPa above ambient
Flow Rate: >500L/min
Weight: 5kg
Product Performance:
When the supply pressure is 0.05-0.15MPa above ambient, rotate the adjustment knob to the fully open position, and the supply valve self-supplies.
When the supply pressure is 1.35MPa above ambient, rotate the adjustment knob to the fully closed position, and the supply valve should not self-supply.
When the supply pressure is 0.9MPa and the breathing flow rate is 40L/min, the inhalation resistance is less than 69Pa, and the exhalation resistance is less than 500Pa.
(Self-supply rate in static state is less than 10L/min)
