Overview
The PAE10 is a ball float air eliminator in cast iron construction with stainless steel internals, designed to automatically discharge air or gas present in a liquid system. It is installed vertically at the high points of a liquid system where air collects, with flow from bottom to top, and removes trapped air that would otherwise reduce heat transfer and air-bind pumps and equipment. Rated to 21 bar(g) maximum allowable pressure and 220°C, with orifice-dependent operating limits. This is a discharge-to-atmosphere device and is not suitable for hazardous or poisonous media. Supplied, sized and serviced for liquid systems across Nepal.
Features & Benefits
- The ball float mechanism responds directly to liquid level, so it discharges accumulated air automatically without any external control or power, which is what makes it reliable at unattended high points across a piping system.
- Removing trapped air from a liquid system restores heat transfer efficiency and prevents air-binding of pumps and equipment, which is the core operational reason to fit one at every high point where air collects.
- Three orifice sizes (1.0, 1.2, 1.5 mm) trade maximum operating pressure against air discharge capacity, so the unit is matched to the actual line pressure rather than compromising on one fixed orifice.
- Viton valve pin gives good chemical and temperature resistance at the sealing point, which is the highest-wear part, and it is available as a spare so the unit is serviceable rather than disposable.
- Cast iron body keeps cost down for general liquid service, appropriate given the non-hazardous media restriction and the 21 bar(g) ceiling.
- Being a discharge-to-atmosphere device, the air it vents escapes locally, which is why it is unsuitable for toxic or poisonous systems by design rather than by pressure rating.
