EFM DAMPERS

With over 35 years of experience Effox-Flextor-Mader (EFM) offers time tested robust dampers to achieve a 20+ year low maintenance design life. Constructed with carbon steel, stainless steel, alloy, and/or corrosion resistant materials our dampers are capable of withstanding temperatures up to 2400° F (1315° C) and the most chemically punishing environments. Our engineering and design team is involved with every project to ensure the structural and dynamic integrity of our products.

BUTTERFLY/WAFER DAMPERS

EFM has installed butterfly dampers from 12 inches (304 mm) in diameter to greater than 120 inches (3048 mm) in diameter. Our butterfly dampers can be found in some of the harshest environments where abrasion, corrosion and dust loading are prevalent.

GUILLOTINE/SLIDE GATE DAMPERS

EFM manufactures heavy-duty low-leak slide gate and zero-leak slide gate dampers to provide isolation for flue gas and air systems. Slide gates, also referred to as guillotine dampers, are required to isolate systems for maintenance or for bypass purposes.

HIGH-PERFORMANCE METAL SEAT WAFER

EFM manufactures high performance metal seat dampers for elevated temperature applications in thermal oxidizers and dirty abrasive environments such as pulverizer outlet dampers. Utilizing a sectioned adjustable metal seal and machined blade seating surface these dampers provide tight shutoff for critical applications.

POPPET DAMPERS

Poppet Dampers are ideal for applications that require quick cycling time and tight shutoff. Poppet dampers are used for isolation capabilities for fabric filter applications and incineration systems. They are engineered to control the reverse gas flow, outlet flow, and bypass flow of gases, in turn enhancing filtration.

RADIAL VANE DAMPERS

Radial vane dampers are used primarily on the inlet of centrifugal fans to direct flow and assist in pre-spinning the flow into the wheel. Radial Vanes are commonly referred to as Variable Inlet Vanes (VIV).
