Apeks

Apeks is manufactured in Blackburn, England, and is owned by the Aqualung Group. The brand was founded in 1974 specifically to produce high-performance dive regulators, and Blackburn remains the manufacturing location today. Apeks holds a number of supply contracts with military and professional diving organisations that maintain rigorous equipment performance standards - civilian recreational equipment is manufactured to the same production specifications.

Apeks uses a sealed piston first stage design with environmental sealing in most of their range - the piston and spring assembly sits in a silicone-oil-filled chamber rather than being directly exposed to ambient water. This prevents the entry of salt, particulates, and biological material into the first stage mechanism, which is particularly relevant for repetitive use in warm, organism-rich tropical water.

The XTX range is Apeks's recreational-focused line - breathing performance is excellent, environmental sealing is standard, and the price reflects recreational use rather than extreme-environment specification. The XL4 is Apeks's traditional piston design with a decades-long track record and a following among technical divers who trust a simple, proven mechanism. Both deliver more than sufficient performance for Malaysian recreational diving conditions.

The MTX-RC (Multiple Tank Crossover) series is specifically designed for technical diving - multiple gas mix capability, high-flow first stage ports for twinset hose configurations, and second stages suited to decompression diving beyond recreational limits. For deep wall diving at Layang Layang or planned decompression dives in Sabah, the MTX-RC provides the gas delivery reliability that technical profiles require.

Apeks equipment is serviced through Aqualung-authorised service centres. Confirm current service centre location and booking availability before purchasing - annual service is mandatory to maintain warranty validity, and the ability to have service completed locally without international shipping is a practical consideration for equipment used regularly at Malaysian dive sites.

Apeks regulators used by dive centres for instructor and rental use regularly accumulate 300-400 dives per year with no performance degradation when serviced on schedule. The Blackburn manufacturing standards produce components that hold tolerance across high usage cycles. For a private recreational diver logging 50-100 dives per year in Malaysian conditions, Apeks equipment can realistically perform without major component replacement for a decade of regular use.
