Among the almost limitless range of products that EMW can custom fabricate are dampers, and we fabricate dampers in stainless steel (as well as in mild carbon steel, galvanized and aluminum) for a range of industries, including the petrochemical, construction and power generation industries.
Why Stainless Steel Dampers?
For durability, corrosion resistance, tensile and shear strength, stainless steel is clearly a good choice. Its long lasting attractive appearance is another reason stainless steel is chosen for many applications, though this is probably not a factor where dampers are concerned. It retains its strength at high temperatures, which can be a factor in extreme environments.
Also a factor is stainless steel’s intrinsically hygienic advantages, making it the correct choice for damper components of ventilation systems in clean room environments, in laboratories, and in pharmaceutical or food processing situations. Stainless steel dampers do not require painting, anodizing or other surface treatments. Stainless steel dampers are also an obvious choice for corrosive environments. And while stainless steel is initially more costly than other materials, its low maintenance needs and long life expectancy can make it cost-effective over the long run.
EMW can use the most common 304 stainless steel alloy, as well as the even tougher and more corrosion resistant 316 stainless steel alloy in the fabrication of our dampers and other products.
Aside from cost, among the factors that might make stainless steel a less appropriate choice for your particular damper application is its relatively high weight.
EMW is a full service metal fabricator offering a wide range of capabilities in the fabrication of stainless steel dampers and other products. These capabilities include:
- CAD/CAM Design and Programming
- CNC precision shearing up to 12 ft. in 1/4" carbon steel, 3/8" aluminum, 3/16 stainless steel
- CNC punching up to 1/4" plate
- 12ft. press brakes up to 350 ton with CNC back gauging
- Saw, torch, and plasma cutting
- Mig and tig welding all alloys
- Rolling up to 1/8" x 5ft. long
- Structural Fabrication (Skids, enclosures, rails, ladders, stairs, stands and more)
- Water Jet precision cutting with a 12ft.x12ft working envelope
We have finishing options (powder coat or wet paint) available when needed. Although we are not paint experts by trade or claim to be, we do offer coating/application services through outside sources. All coating will be at the customer's request and specification. In order that the customer receives the proper coating for their exact application all specifications must come from and be approved by the customer prior to coating. EMW does not make coating recommendations for any application. Essentially, you tell us the kind of coating or finish you need or prefer and we will make sure that coating or finish is applied properly.
A variety of finishing options are available when needed.
Types of Dampers Fabricated in Stainless Steel
Diversification and custom fabrication are watchwords for us at EMW, so the following list is merely a summary of some standard types of dampers we can produce in stainless steel and mild steel:
- Backdraft Stainless Steel Dampers: Backdraft dampers only permit air to flow in one direction in a duct or airway. They are commonly used to prevent outside air from entering a building through an exhaust duct.
- Manually Operated Stainless Steel Dampers: Manually operated dampers are simply dampers, which are set by hand, as by the operation of a handle that sits outside the duct that the damper controls.
- Motorized Stainless Steel Dampers: In motorized dampers, the plates or flaps, which control, block or allow the draft or airflow are actuated by motors. These motors are often linked to thermostats, for instance in zone controlled air conditioning systems.
- Opposed Blade Stainless Steel Dampers: Opposed blade dampers are an alternative to the standard parallel blade damper configuration. Airflow characteristics are different when an opposed blade damper is fully open, versus an open parallel blade damper, and these differences can be significant in certain applications.
- Heavy Duty Stainless Steel Dampers: Heavy-duty dampers are similar to standard duty dampers except they are formed with special reinforcement to provide greater rigidity and strength. They may be needed for applications where especially high airflow velocities are involved.
Stainless Steel Dampers Formed to Fit Your Requirements
Our dampers are created through a metal forming process (not through a metal extrusion process), which gives us the flexibility required to fabricate a unique stainless steel damper product that fits the requirements of each customer's application. EMW's metal forming process also allows for the fabrication of a damper that meets close tolerances.
Whether you have CAD drawings ready or just verbal instructions to provide, you can be confident that EMW has the experience, know-how and determination to follow-through on your project and fabricate a custom damper that will fit your application.
