Our policy for after-sales is to be able to repair and service all the equipment we sell. This is achieved by training our staff at the mother companies, investing in repair equipment and fully equipped workshops, have the necessary availability of spare parts in stock and above all have the right experience and knowledge!



SCUBA Cylinder hydrostatic pressure testing, visual inspection and valve repairs


Scuba cylinders are designed to be extremely tough and to provide many years of safe and trouble-free diving. Nonetheless a cylinder must be well cared for and properly maintained by visual inspection and hydrostatic testing. Scuba cylinders must undergo visual inspection every 2.5 years and hydrostatic testing every 5 years.


We service (scuba cylinder visual inspection and scuba cylinder hydrostatic pressure testing) all kind and sizes of gas, scuba cylinders and BA cylinders according to standards such as EN1986 and EN1802. SalpaSub also offers sand blasting (shot blasting) of diving cylinders, tumbling, oxygen compatible anti-rust treatment, repainting (1 or 2 compound paint) and accessories such as cylinder valve parts, replacement valves, nets and boots.

Compressor Repairs and Installation


SalpaSub is the authorised distributor, repair and service center for Aerotecnica Coltri compressors in Malta and Gozo. Units vary from small portable pumps filling 100l/min of air to filling stations (up to 600l/min) and can be fully equipped with all safety features, digital control panels, air dryers, filling panels and automation. The compressors are driven by electric motors (single or three phase) or petrol or diesel engines.  Silenced versions and units for temperate regions are also produced for most sizes. The compressor chassis is also available in stainless steel.  If you would like to fill Nitrox you can choose from the range of LP Nitrox compressors or membranes.


Coltri compressors are used for SCUBA diving, SCBA (firefighting applications) and also in other sports such as paintball! Have a look at our product range HERE.


Apart from selling compressors we also hire compressors and we offer a replacement unit until the repair on your filling station is finalised.


SalpaSub technicians repair and service compressors and can overhaul the compressor completely to 0 hours including sand-blasting and repainting of chassis, setup of additional filtration system  and repair electronic sensors, boards and components.  We stock a large range of spare parts and consumables thus we offer a quick and timely service. Repairs can be carried on site (ships, private boats and super yachts, diving schools) or at our workshop and a log of all the repairs carried out will be registered. We will take complete care of your compressor and we will also inform you when the next service is due to make your life easier!


Coltri Compressors now also have a range of fill containment cabinets (also known as boom boxes) that can fill from a single cylinder up to four cylinders at a time. You can find these products here
