A new course introduced by popular demand from DITC students to teach the skills necessary to service and repair the Oxygen Booster pumps that support rebreather operations worldwide. More than 10,000 recreational rebreathers are now in use, which together with a century of military rebreather use in the worlds navies generates a requirement for technicians with the specialist skills to service these items.

The course covers general maintenance, operation, standards and relevant legislation across all major manufacturer’s products.

Includes:

• Haskel Oxygen Booster Pump Maintenance Certification establishing the legally competent person status of the technician to work on these systems.
• All student training Manuals used during the course + online access to the ScubaEngineer.com technician database.
• All spare parts & consumables used during the course.
• Free Tea/Coffee and high-speed Wi-Fi internet access at the training center.

Pre-requisites:

• Applicant must show proof of Oxygen service technician training (Any agency accepted)

Key Benefits

• Prevents costly damage to the Haskel unit through incorrect use/lack of proper maintenance
• Provides proof of formal Haskel pump service & repair training. When a new Booster pump stops working, manufacturers often blame the operator or the owner if the person responsible for the unit has no training. If the Haskel Booster pump operator has formal training and the unit was being maintained and used correctly, the blame for the system failure shifts to the manufacturer, supplier or previous repair agent involved in servicing the unit.
