Perforated Metal HVAC Applications
Perforated metal products are used in the HVAC industry in diffusion systems and air ducts. It's the perfect medium to:
- Distribute air evenly
- Act as a silencer
- Be aesthetically pleasing as a filtration media holder
Perforated Spiral Coil – Perforated Ductwork
Perforated metal serves as the inner wall of HVAC ductwork. The prime coils we perforate are sent to be formed into a pipe through a spiral lock seam method.
We stock perforated coils for the HVAC industry based on the following specifications:
• 5.394” x Coil
• 22 Gauge (.0296” min)
• 24 Gauge (.0236” min)
• Coils Up to 60" Wide
• Perf Pattern RS027 (3/32” on 3/16” Staggered, 0.093” x 0.187”)
• 22.7% Open Area (32.84 holes per square inch)
• ASTM A653 Type B
• Material is Hot Dipped Galvanized at the Mill
• G60 Coating Weight – Inquire about others
Other Application - Inner Metal Shell
- Perforated metal – standard material is a 23% open area pattern with 3/32" holes on 3/16" centers, staggered.
- Perforated metal with erosion barrier—This is a standard perforated material with an additional protective layer of Mylar between the insulation and the perforations opening into the airstream. Please note that the Mylar film is an excellent erosion and vapor barrier. Still, its use may affect the acoustical performance of a double-wall duct and alter the flame spread and smoke development numbers.
Diffusers
Using perforated metal in HVAC air diffusers helps to initially distribute the airflow. There are no cold floors, blasts of heat or arctic temperatures on occupants, or stale air. A room with dispersed air is the best environment for work or play.
Accurate Perforating supplies perforated metal components in various materials to manufacturers and suppliers in the heating, ventilation, and air conditioning industries. With a 50 percent to 60 percent open area in the perforated metal, we can ensure even temperatures and airflow in any size building.
Silencers
Fan noise and HVAC system noise can move right through air hoses in the duct system, sending undesirable sounds throughout an entire building. No one functions well in an environment with unwanted noise.
The use of an HVAC perforated metal silencer can mitigate this. It's the ideal medium to break up the linear airflow and quell noise pollution. Many silencers have an open area of 18 percent, but Accurate Perforating supplies components have an open area of 23 percent, which is the ideal percentage that really works. Perforated metal also acts as a media (filter) holder in the ducts, holding the filter that delivers cleaner, more comfortable air.
