As a professional manufacturer with its own advanced factory in China, SunKai has long been committed to providing high-quality marine anti-collision solutions for global customers. The SunKai Marine Low Pressure Pneumatic Fender is a professional anti-collision equipment specifically designed for ship berthing and mooring scenarios, serving as a core protection tool in port, wharf and ship operations.
This fender adopts a low-pressure inflatable structure, which can effectively absorb and disperse the impact force between ships and docks or between ships, avoiding damage to the hull and port facilities. Its core structure uses high-strength synthetic fiber fabrics (such as nylon and polyester) as the inner tube skeleton, and the outer layer is covered with wear-resistant and anti-aging rubber or PVC materials. By filling low-pressure air (usually working pressure 0.02-0.08MPa), it forms a flexible buffer that provides soft and reliable protection. With excellent performance characteristics such as high impact capability, strong environmental adaptability and outstanding cost-effectiveness, it is widely applicable to small yacht berths, large container ship terminals and other scenarios, becoming a cost-effective choice for factories and ports.
The fender is manufactured through a strict four-step process: material pretreatment, inner tube forming, outer wrapping, and detection and repair. Each step is subject to strict quality control, ensuring that every product meets high standards of airtightness, impact resistance and durability. Its unique characteristics include high anti-collision shrinkage and twisting capacity, new explosion-proof structure design, optimized structural layout, and strong seawater corrosion resistance, making it capable of maintaining stable performance even in harsh marine environments.
Our advanced Low Pressure Pneumatic Rubber Fender is engineered to deliver exceptional performance and durability. This system is the ideal choice for a wide range of maritime applications, from large commercial harbors to specialized terminals. Specifically designed for vessel protection, the Ship Low Pressure Pneumatic Fender offers a robust barrier that minimizes hull damage and reduces maintenance costs. The core technology utilizes a Pneumatic Fender Low Pressure Type design, which allows for a larger contact area and smoother energy absorption curve compared to high-pressure alternatives. For operations requiring enhanced visibility and stability in dynamic water conditions, our Floating Low Pressure Pneumatic Fender provides a reliable and highly visible solution that remains effective even in challenging sea states.
The Marine Low Pressure Pneumatic Fender distinguishes itself through a combination of superior material science and precise engineering. Its construction features a reinforced rubber casing that is highly resistant to abrasion, ozone, and weathering, ensuring long-term performance in harsh marine environments. Internally, the low-pressure air chamber is designed to compress gradually upon impact, providing a consistent and predictable reaction force that safely decelerates vessels. This design principle offers significant advantages, including higher energy absorption per unit weight and a lower reaction force for a given energy absorption level, which directly translates to enhanced safety for both the vessel and the berthing structure. Key operational parameters are detailed below to illustrate the product's specifications and capabilities.
- Regular Air Pressure Inspection: Use the built-in pressure gauge to check the internal air pressure regularly (it is recommended to check once a week under normal use). Ensure the pressure is within the standard working range of 0.02-0.08MPa. If the pressure is insufficient, use the inflation valve to supplement air in a timely manner to avoid affecting the buffer performance.
- Surface Cleaning & Inspection: Regularly clean the outer surface of the fender to remove seawater stains, sludge, debris and other attachments, preventing the outer rubber/PVC layer from being corroded or worn. At the same time, check for scratches, cracks, bulges or damage on the surface; if any damage is found, repair it promptly to avoid air leakage.
- Sealing Performance Check: Conduct an airtightness test every 3 months. Fill the fender with low-pressure gas (approximately 0.05MPa) and let it stand for 24 hours to observe the pressure change. If the pressure drops beyond the standard range, find the leak point immediately and repair it to ensure the fender’s sealing performance.
- Proper Storage When Not in Use: When the fender is not in use for a long time, deflate it completely, clean and dry the surface, and store it in a cool, dry and well-ventilated place. Avoid direct sunlight, high-temperature baking, or contact with sharp objects to prevent aging or damage of the outer layer material.
- Accessories Maintenance: Regularly check the inflation valve, pressure gauge, lifting ring and other accessories. Ensure the inflation valve is tightly sealed without air leakage, the pressure gauge displays accurately, and the lifting ring is firm and not loose. Replace damaged accessories in a timely manner to ensure the normal use of the fender.
- Avoid Contact with Corrosive Substances: Prevent the Marine Low Pressure Pneumatic Fender from contacting strong acids, strong alkalis and other corrosive substances, which may damage the outer rubber/PVC layer and inner tube skeleton, affecting the service life and performance of the product.

- Q: What is the working pressure range of SunKai Marine Low Pressure Pneumatic Fender?
A: The usual working pressure range of our Low Pressure Pneumatic Fender is 0.02-0.08MPa. We recommend maintaining the pressure within this range to ensure optimal buffer performance and avoid potential safety hazards caused by excessive or insufficient pressure.
- Q: Can the fender be used for both small yachts and large container ships?
A: Yes, it has high flexibility and adaptability. We can customize fenders of different diameters and lengths according to the berth width and vessel tonnage requirements, making them suitable for use at both small yacht berths and large container ship terminals, meeting the anti-collision needs of various types of vessels.
- Q: How long does the airtightness test of the fender take, and what is the standard?
A: The airtightness test of each fender takes 24 hours. We fill the fender with low-pressure gas (approximately 0.05MPa) and let it stand. If the pressure drop does not exceed the standard range within 24 hours, it is considered qualified, ensuring that the fender has good sealing performance and no air leakage.
- Q: What is the difference between the 80Kpa and 50Kpa fenders in terms of use?
A: The main difference lies in the initial internal pressure and performance parameters. The 80Kpa fender has higher guaranteed energy absorption and reaction force, suitable for larger tonnage ships or scenarios with greater collision impact; the 50Kpa fender is more suitable for small and medium-sized ships or scenarios with relatively small collision force, and both can be selected according to actual needs.
- Q: Can the fender be used in seawater for a long time, and will it be corroded?
A: Yes, it can be used in seawater for a long time. The outer layer of the fender is made of wear-resistant and anti-aging rubber or PVC materials, which have strong seawater corrosion resistance. Long-term immersion in seawater will not cause cracking, aging or corrosion, ensuring stable performance.
- Q: Is professional personnel required for the installation of the fender?
A: No, professional personnel are not required. The fender has a lightweight design, and installation does not rely on large lifting equipment. It can be completed manually with simple tools, and the whole process is simple and efficient, which can be operated by ordinary operators.
- Q: What should I do if the fender is scratched and leaks air?
A: If the scratch is small, you can use the special repair material provided by us to repair the leak point by following the maintenance guidelines; if the damage is serious, please contact our after-sales team in a timely manner, and we will provide professional repair suggestions or replace the damaged parts.
