The package combines cylinders, manifold and bands; additional mono valves are not required.

Oceanauts setup & collection

Select “Oceanauts setup & air fill — collection only” to add £85 including VAT to the component package price. The displayed setup-option price includes this charge.

• Initial inspection of both cylinders
• Manifold installation, band assembly and alignment
• Contents stickers and leak check
• Initial air fill for both cylinders

Collection from Oceanauts only. Assembled, filled cylinders cannot be shipped. We will contact you when your order is ready; setup does not imply immediate collection. The listed manifold and bands are included. Oxygen cleaning and Nitrox fills are separate services.

Available to order — usually at Oceanauts within 1–2 working days when in stock with our UK supplier. This is the estimated time to reach Oceanauts, not delivery to your address. We will confirm supplier availability and your dispatch or collection timing. If you select Oceanauts setup and an air fill, collection will be arranged after inspection and assembly are complete.
