APOLLO Bio Regulator A-320 YOLK NRX

A yoke-connection version of Apollo’s adjustable A-320 NRX regulator, built for divers who want the same nitrox-ready and cold-water-oriented performance in a standard yoke configuration. The balanced, environmentally sealed first stage and adjustable second stage are aimed at providing smooth, controlled breathing and better long-term versatility than a basic entry-level regulator. Ready for up to 40 percent nitrox and supplied as a polished higher-spec option, it is well suited to divers who want comfort, reliability, and room to grow into more advanced diving without switching systems. 

The High Pressure Seats are tested and can perform 3,000,000 breath cycles or approximately 3,000 dives

The Apollo High Pressure Seat has been tested to temperatures of -29°C with no reduced performance

Bio Air System

B.A.S. means Bio Air System. Apollo use a high performance internal bypass venturi system in the 2nd stage.

The internal bypass venture system supplies smooth consistent gas delivery irrespective of the air pressure and change of depth

Low Pressure Hose with Swiveling Ball Joint

The Apollo high quality hose has ball shaped joint that allows the 2nd stage 39°movement to each side.

The Apollo Low Pressure Hose with Ball Joint leads the world in comfort and reduced jaw fatigue

Purge Cover

The soft durable purge cover is made from high quality polyurethane

Airflow adjusting knob

Simple and easy to operate

Turn the adjusting knob clockwise to decrease gas volume supply. Turn the adjusting knob anti-clockwise to increase gas volume supply

Corrosion repellent plating

The metal components of both the 1st and 2nd stage of the regulator are processed using a corrosion repellant plating (Zeomic Plating) This offers you unrivalled protection against corrosion and bacterial formation

Viton O-ring

All O-rings used on the 1st and 2nd stage are made from Viton this allows Nitrox use up to 40% straight out of the box

High Pressure Seat

The Apollo High Pressure Seat is made from incredibly tough urethane.

This Apollo High Pressure Seat has gone through an extensive testing program. The High Pressure Seats are tested and can perform 3,000,000 breath cycles or approximately 3,000 dives

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.

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
