AMETEK Adds New Combustion Blower to Advanced Motion Solutions

June 28, 2021 by Alessandro Mascellino

Electronics manufacturer AMETEK has added a new combustion blower to its Nautilair Combustion Product Line.

The Nautilair Pro 14" combustion blower is designed to provide hydronic system manufacturers with a bigger, more powerful, and performant option.


Designed for Larger Boiler Applications

Many hydronic systems today require larger boilers, which, in turn, need more airflow. The Nautilair Pro 14" is designed to fit into this market segment, alongside the existing 7.6", 8.9", and 12.3” blowers. For context, the Nautilair product line can accommodate airpower levels from .05M up to 6M BTU/hr. It can also withstand voltage inputs of 120VAC, 240VAC, and 380-575VAC.

“The Nautilair combustion blower line offers a comprehensive selection for the most common applications on the market today,” said Kevin Martin, Applications Engineering Manager at AMETEK DFS, commenting on the news.


Technical Specifications

The Nautilair Pro 14" is capable of airpower to reach heating levels up to 6M BTU/hr. It also features a high sound reduction design and high power density for more reliable performance, offering up to 1700 CFM and 28 inches of water.

To facilitate installation, AMETEK’s new combustion blower features retrofit capabilities with design flanges the same size as the existing Nautilair 12.3". In addition, the Pro 14" offers global compatibility with a three-phase line voltage of 380-575 VAC, and with Siemens PBA137 valve and LMV-3 controller.


The Nautilair Combustion Blower Line

AMETEK first started the Nautilair combustion blower line in the late 1990s. All the devices in this family are variable speed brushless blowers, engineered to deliver a measured air/fuel mixture in gas-fired burner systems to optimize combustion and reduce nitrous oxide and carbon monoxide emissions. 

These Nautilair combustion blowers are currently used in various applications, including commercial and residential boilers, hot water heaters, furnaces, food service equipment, kilns, and fuel cells, among other industrial applications. The devices are also typically used as alternatives to several traditional solutions.

These include speed and two-speed blowers, intake damper systems on fixed speed blowers, and inverter-driven variable-speed blowers. The Nautilair combustion blowers can also be used with a modulating gas valve to suit a wide range of system designs.

The combustion blowers’ speed can either be adjusted internally with an onboard potentiometer or externally via a PWM or DC control that varies the blower’s performance, thus eliminating the need for complex air intake damper systems. 

In terms of power supply, the Nautilair’s internal electronics convert AC input to DC, and the blowers can typically operate for more than 20,000 hours, with reportedly very little maintenance required.
