Apeks Tek 3 1st Stage Set

Apeks Tek 3 1st Stage Set. Apeks has developed unique 1st stages specifically for use on a twin set.

We have now launched the new TEK3 1st stage regulators designed for use with twin cylinder configuration.

The system benefits from streamlined hoses with little chance of accidental snagging and also improved ease of access to cylinder valves.

Each 1st stage has 3 medium pressure ports and one high pressure port.

They are balanced, cold water compatible and extremely robust. TEK3 looks great too.

Another clear benefit for divers is the ease of access to the cylinder valve knobs.

Vitally important during dives.

The TEK3 1st stages have been designed and tested for use with any Apeks cold water spec second stages.

The choice is yours. We are sure this is a leap forward for extended range diving, wreck diving, cave diving, in fact any diving where twin set use is preferred.

Cressi First Stage Ac10

Cressi First Stage Ac10. The AC10 1st stage is the latest version of the Cressi balanced piston model, manufactured for many years and highly appreciated for its exceptionally durable and reliable characteristics.

1st stage AC10



The 1st stage is the renowned Cressi AC10 balanced piston model.

It can be supplied with international yoke or with 200 or 300 bar DIN connections.

This balanced piston first stage means performance remains constant, irrespective of depth and pressure from the tanks.

With the continuous reviews and improvements over the years all the air passages inside the first stage have been completely redesigned and considerably increased so as to give the excellent performance that AC10 offers today.

Alongside this excellent performance, the AC10 boasts simple mechanics, resistance to wear and tear and requires so little upkeep that it has become a product with legendary reliability.

It has some 5 low-pressure ports located right around a swivel head, which guarantees rational hose positioning on any valve.

We must also point out the quick and really handy external system to regulate intermediate pressure, which can be calibrated in a few seconds with a normal Allen key and the extremely powerful sintered filter system to filter air from the tanks.
