Double Diaphragm System

The Bio regulator has double diaphragm system that prevents any water from entering the 1st stage. If there is no water inside the 1st stage you eliminate the possibility of any corrosion

The Double Diaphragm System makes the Bio regulator ideal for cold water diving. If water enterers the 1st stage it is possible for metal components to freeze. By eliminating water entry in to the 1st stage you also prevent metal components from possibly freezing and then sticking which would prevent the 1st stage from working correctly

Stainless Steel Bucket Mesh Filter

The Apollo Stainless Steel Bucket Mesh Filter has more surface area than standard flat filters. The bucket filter with a larger surface area gives it the ability to filter the incoming gas from the scuba cylinder without reducing air flow

Regulators that do not use Stainless Steel Filters need to be replaced when serviced. The Apollo Stainless Steel Bucket Mesh Filter is cleanable and then reused. By reusing the filter you reduce the parts cost of an annual service.
