Air Vent Head for Marine Tank Protection
Reliable Tank Ventilation with Seawater Protection
The Pres-Vac Air Vent Head is designed to provide safe and efficient ventilation of ballast and fuel tanks across a wide range of vessel types, including oil tankers, chemical tankers, container vessels, drilling rigs and passenger ships.
The primary function of the air vent head is to allow air to enter and leave the tank freely preventing excessive overpressure or vacuum conditions and prevent seawater from entering the tank.
Controlled Ventilation and Tank Protection
During loading and discharge operations, air must move in and out of the tank to maintain structural integrity. The air vent head ensures:
- Free passage of air during normal operation
- Prevention of excessive tank pressure or vacuum
- Protection against seawater ingress
- Controlled overflow discharge in case of overfilling
- Some sizes certified for flame transmission for fuel tank installation
The integrated float mechanism prevents seawater from entering the tank in heavy weather conditions, safeguarding cargo quality and vessel safety.
Designed for Marine Compliance
The Pres-Vac air vent head is engineered in accordance with international maritime requirements and classification society standards. The robust mechanical design ensures long service intervals and reliable performance in harsh marine environments.
Key Benefits
- Suitable for multiple vessel types
- Prevents seawater ingress
- Protects against overpressure and vacuum
