Envotec Model ETA-4 Automatic Air Vents: Elevating Plumbing, HVAC, and Firefighting Systems

Envotec’s Model ETA-4 Automatic Air Vents are indispensable components in plumbing, HVAC, and firefighting systems. They serve a crucial role by continuously eliminating potentially hazardous trapped air from these systems, all without the need for manual intervention.

Key Benefits of the Envotec Model ETA-4 Automatic Air Vents:

• Enhanced System Performance: Air trapped within piping systems can lead to a host of issues, including excessive noise, reduced precision of control valves, and compromised heating and cooling equipment efficiency. Envotec Automatic Air Vents tackle these challenges head-on.
• Efficient Air Release: One of the primary functions of the Envotec Automatic Air Vent is to expel air during the water-filling process, ensuring a smooth, air-free system operation. It then seamlessly isolates and prevents water loss from the system.

Top-Notch Construction for Enduring Performance:

• Solid DZR & Heat-Resistant Polypropylene: Crafted from high-quality solid DZR (Dezincification Resistant) brass and heat-resistant polypropylene, these vents are built to last. Their durability ensures optimal performance even in demanding piping systems.
• Resistant to Dezincification and Corrosion: The vents exhibit excellent resistance to dezincification and boast high general corrosion resistance, providing longevity and reliability.
• Ease of Inspection and Cleaning: Designed for practicality, these vents can be easily disassembled for inspection and cleaning, ensuring they remain in top working condition.
• High-Temperature Resistant Float: The float within the vents is constructed from high-temperature-resistant polyethylene, guaranteeing its effectiveness even in high-heat environments.
• Impurities Resistant: These vents are engineered to maintain functionality, as impurities typically do not interfere. The maximum float line of water always remains below the valve seal.

Technical Specifications:

• Maximum Working Pressure: The vents are rated to handle a maximum working pressure of 174 psi (12 bar), making them suitable for various applications.
• Maximum Working Temperature: With a capability to operate reliably at temperatures up to 120ºC (248ºF), they are versatile and compatible with diverse environments.
• Connection: Featuring male threaded connections, they seamlessly integrate into your existing system.

Upgrade your plumbing, HVAC, or firefighting system with the Envotec Model ETA-4 Automatic Air Vents. These vents offer not only reliability and longevity but also efficiency in eliminating trapped air, ultimately optimizing the performance of your system. Say goodbye to excessive noise and control valve inaccuracies – trust Envotec to keep your systems running smoothly.
