Air Separators

Working Principle:

Air separators leverage the principle that air is less dense than the liquid in the system. As fluid flows through the separator, the design (e.g., baffles or mesh) slows the flow, causing air to separate and rise. A float valve or automatic air vent then releases the collected air. Some models use coalescing media to enhance air capture.

List item

Air separators, also known as air eliminators or air scoops, are devices used in heating, cooling, and hydronic systems to remove entrained air from liquids, typically water or glycol mixtures. They work by directing the fluid through a chamber where the flow slows, allowing air bubbles to rise and collect at the top. The trapped air is then vented automatically or manually through a valve, improving system efficiency and preventing issues like corrosion, noise, and reduced heat transfer.

Key Functions

Air Removal: Separates dissolved or entrained air from the system fluid, ensuring optimal performance.

Types: Common designs include centrifugal, tangential, and in-line air separators, each using different methods to isolate air.

Materials: Typically constructed from cast iron, steel, or brass for durability and corrosion resistance.

Applications: Used in HVAC systems, chilled water systems, hot water heating, and industrial processes.

Benefits: Reduces pump cavitation, extends equipment lifespan, and enhances energy efficiency by minimizing air-related blockages.

Features:

Body – Mild Steel

Size – 80MM to 650MM

End Connection – Flange

Installation and Maintenance:

Air separators are critical for maintaining system performance, reducing maintenance costs, and ensuring quiet, efficient operation in hydronic and HVAC systems.

Installed at points where air is likely to accumulate, such as high points in piping or near heat sources.

Regular inspection is needed to ensure vents are functioning and no blockages occur.

Some models include strainers to capture debris, requiring periodic cleaning.
