The Flamco Smart series of air and dirt separators from Nexus remove even the smallest microbubbles and minuscule dirt particles from the system water. Thanks to the innovative design, the pressure loss in the system is kept to a negligible minimum. The 360° rotating connection and compact dimensions of the Flamco Smart series enables them to be easily installed even when space is limited.

Curious about what’s on the inside of Nexus’ ASME rated air & dirt separators? Nexus produced a new video to take a look.

As you’ll see, there is no coalescing media that can become clogged. The video showcases a close up of the separating element, the stack of powerful Neodymium magnets in the base, and the dual dirt scraper at work inside the separator.

Nexus utilizes an engineered stainless steel separating element. The separator pushes the air up to the Flexvent Super air vent and the dirt particles down into the base. The stack of powerful Neodymium super magnets in the base grabs the magnetite from the fluid stream until the dual-edged dirt scraper breaks it loose in preparation for a clean, complete blowdown. The dirt scraper feature is unique to Nexus.

Sometimes really cool projects fall your way. This giant stainless-steel air separator was one of them. A customer called asking if Taco made “custom” tanks, air separators, etc. Of course, Taco is capable of building virtually anything made of metal / steel that can be fabricated, and everything is ASTM certified. The customer needed a VERY large, custom air separator for a process application and the system required that the air separator be constructed entirely of stainless-steel.

Removing air and dirt from any hydronic system is critical to maximizing system efficiency and most importantly, for prolonging the life of the pumps and the rest of the equipment in the system. The project was a tall order, literally, but Taco was up to the task!

Custom Design

The design was based on Taco’s top-of-the-line 4900 series air and dirt separator with some very unusual dimensions; 132” (11 feet) tall and 66” (5.5 feet) in diameter. Flow requirements necessitated the tank to be 30” in diameter!

Once we had the requirements from the customer, we asked Taco engineering to provide design and full submittals, including drawings, pressure drop calculation and minimum / maximum conditions of the unit. After the submittals comments and design were finalized, the unit was released for fabrication using ½” wall, 304 stainless-steel. All work was performed in-house by Taco craftsman, using Taco equipment, including rolling the ½” wall steel on their own rolling equipment. Taco’s fabrication shop, certified welders and capabilities are second to none in the industry!

A Small COVID-19 Setback

The project began, just as the COVID-19 virus hit, requiring Taco to shut down briefly, then adjust to local (Massachusetts) state ordered production rules. This reduced the total weekly operating hours, limiting them to four-day shifts, and requiring sanitization of the entire facility at the end of each week to ensure the safety of their employees.

Despite this, Taco’s Fall River Massachusetts facility (the pumps and drives are made in Rhode Island) completed the fabrication, pressure tested the unit and shot-blasted it prior to shipping it. According to Anthony DeMoura, Taco’s Vice President of the Fabricated Products Division & PIFA Foundry Operations, this was the largest stainless-steel vessel they have ever made.

Specialized Shipping

A specialized cartage company had to be used because the air separator weighed four tons! As you can see from the photos, the design, transportation, and install was a tremendous success! Everyone involved in the project pulled together in order to make this custom air separator and the unit was featured in this month’s Taco newsletter.

One of our top selling manufacturing product lines, Nexus Valves, has started a new Fast Facts video series on some of their products. They are short, to the point, and very helpful. Please take two minutes to watch them and you’ll be glad that you did!

The first one is on the Flamcovent Clean Smart air separator, which removes even the smallest microbubbles from the system water. Air and dirt in an installation cause problems like unnecessary breakdowns and extra wear or noise, but also lead to disruptions in the installation, less heat transfer and reduced pump performance. The result: higher energy consumption and an unreliable installation.

The Flamcovent Clean Smart air separator is virtually maintenance-free with a negligibly low flow resistance. The air and dirt separator can be incorporated in a variety of heating and cooling systems and in every desired direction. The absence of obstructions in the main flow ensures that clogging or blockage is prevented which guarantees superior and continuous operation over its service life. The air chamber of the separator is conical in shape leaving little chance of contamination. According to Nexus, the Flamcovent Clean Smart air separator offers 60% better performance compared to conventional separators.

Here’s the Nexus Fast Facts video, hosted by Nick Hallowell, featuring the Flamcovent Clean Smart air/dirt separator.

And, here’s an illustrated video of how the product works.
