High Pressure Scuba Diving Breathing Compressor

The SLT-680 high-pressure breathing air compressor is designed for professional scenarios requiring a supply of high-pressure, clean breathing air. Typical applications include:

• Firefighting and Emergency Rescue: Deployed at fire station air supply depots or on fire vehicles, it enables on-site refilling of breathing air cylinders for firefighters during operations involving fires, heavy smoke, toxic gases, or chemical leaks, ensuring personnel safety.
• Diving and Underwater Operations: Widely used in sectors such as diving clubs, offshore aquaculture, commercial fishing, maritime rescue, underwater engineering, salvage operations, shipbuilding, and water parks, providing divers with compressed breathing air that meets international standards.
• Industrial and Mining Operations: Provides a safe and reliable air supply for personnel working in environments where oxygen deficiency or hazardous gases may be present, such as underground mining, tunnel construction, and chemical plant maintenance.
• Other Emergency Rescue Operations: Can be used at the sites of natural disasters-such as earthquakes or floods-to provide breathing air support for rescue personnel.

Although both are air compression devices, there are fundamental differences in terms of design standards, output pressure, air quality, and safety requirements:

Although the SLT-680 is a cabinet-enclosed model, its safety protection system applies equally to both portable and stationary high-pressure breathing air compressors. Key safety measures include:

• Pressure Safety Protection: Each compression stage is equipped with an independent safety valve that automatically releases pressure if the limit is exceeded; the system also features an automatic shutdown function that stops operation when the cylinder pressure reaches the preset value, preventing over-pressurization during filling.
• Electrical Safety Protection: Includes multiple safeguards such as motor overload protection, over-voltage and under-voltage protection, phase sequence protection (to prevent motor reverse rotation), and star-delta soft starting (to reduce startup surge).
• Temperature Safety Protection: An integrated temperature control system monitors exhaust temperature in real-time; it triggers an alarm and shuts down the unit if the temperature exceeds safe limits, preventing equipment damage or lubricant carbonization caused by high heat.
• Emergency Shutdown Protection: A manual emergency stop button allows operators to instantly halt the machine and cut off operation upon detecting any abnormality.
• Structural Safety Protection: The enclosed cabinet design prevents accidental contact with hot or moving parts while also providing sound insulation and noise reduction.
• Automatic Condensate Drainage System: High-pressure condensate is automatically drained from the separators at timed intervals, preventing liquid accumulation that could cause liquid hammer damage to the compression chamber.

Yes. Regular maintenance is crucial for ensuring the equipment's long-term stable operation, extending its service life, and guaranteeing that the output air quality meets standards. The recommended maintenance schedule is as follows:

Before long-term shutdown (exceeding one month) and upon restarting, the following measures are recommended:

Preparation before shutdown:

• Clean the exterior of the equipment to remove accumulated dust and oil stains.
• Replace lubricating oil and filter elements that have been in service for a long time to prevent the old oil and filters from degrading or harboring bacteria during the shutdown period.
• Drain condensate from all separators and pipelines to prevent accumulated water from corroding internal piping.
• Store the equipment in a dry, well-ventilated, and dust-free indoor environment.
• Cover the equipment with a dust cover to prevent dust from entering air intakes and crevices.
• Disconnect the power supply and properly stow the power cord.

Checks before restarting:

• Thoroughly inspect the power cord and electrical connections to ensure they are intact.
• Check the oil level; top up or replace the lubricating oil if necessary.
• Check for loose pipe connections and ensure the safety valve is in good condition.
• Manually check that all drain valves operate smoothly.
• Perform a brief low-pressure test run to monitor pressures, temperatures, and drainage; proceed to normal operation only after confirming there are no abnormalities.
• If the equipment has been idle for more than six months, it is recommended to contact the manufacturer or a professional technician for a comprehensive inspection before restarting.
