MAKO COMPRESSORS MAKO DOLPHIN Breathing Air Compressor: Common Faults and Maintenance

MAKO COMPRESSORS is an American manufacturer of diving and breathing air compressors. The MAKO DOLPHIN is typically used for rescue and emergency response. This guide summarises its applications, typical faults and the consumables that keep it running reliably.

Common faults and diagnosis

Oil carry-over

Excess oil consumption often signals worn rings or a blocked separator element; both affect air purity and should be checked early.

Filter saturation

Clogged activated-carbon and particle filter cartridges cause pressure drop and longer fill times. Replace filter elements at the recommended interval and after any noticeable taste or odour.

Low or unstable pressure

Intermittent pressure loss often traces to an intake restriction or a sticking check valve rather than the pump itself.

Compatible consumables

We supply generic, compatible consumables for the MAKO COMPRESSORS MAKO DOLPHIN, including breathing-air compressor lubricating oil and breathing filter cartridges (activated-carbon and particle stages). These are aftermarket replacement parts; we are not affiliated with MAKO COMPRESSORS and do not represent the original manufacturer.
