Our 8″ Blower Silencer is designed as a drop-in compatible replacement for common 8″ flanged blower silencers used in pressure and vacuum applications.

Same Fit. Same Performance. Built Here. Built to Last. 🇺🇸

The B8-LAF 8″ silencer delivers equivalent acoustic attenuation and pressure drop performance to established industry models — with the added advantages of domestic manufacturing, BABA compliance, thicker steel and a durable powder coat finish.  The silencer has an L-style layout with 8″ ANSI flange connections and it can be used on either the inlet or discharge side of the blower.

Designed for Easy Replacement

Our 8″ flanged blower silencer is engineered to match the dimensions of common industry models, making it ideal for fast maintenance swaps, emergency replacements, retrofit upgrades, and municipal compliance conversions.

This 8″ blower silencer is a drop-in equivalent for other common silencer models: RISY-8, SDY-8, D32H-8. If you’re unsure about compatibility, send us details about your existing silencer and our experienced team will be happy to assist you with replacement.

Equivalent Performance you can rely on

Our industrial blower silencers have equivalent acoustic attenuation and pressure drop performance to established industry models. 

These silencers can be used on either the inlet or discharge side of the blower.  For the best performance, your blower silencer should be located as close as possible to the blower connections, and should sit between the blower and any control or check valves.

Built for Durability, Even in the Harshest Environments

After extensive testing, we determined that constructing our silencers’ shells from thicker 11 gauge steel met our attenuation requirements while also making our silencers much more durable.  And unlike other brands that ship silencers with only a basic primer coating, our pdblowers blower silencers feature an industrial-grade powder coat finish for the most dependable performance.

• Better corrosion resistance
• Improved abrasion durability
• Longer service life
• Cleaner appearance over time

In facilities where moisture, chemicals, and constant operation are part of daily life, durability isn’t optional.

Custom Options to meet your unique requirements

We’re not just an industrial supplier, we’re blower system specialists with over 35 years of engineering and fabricating pressure and vacuum systems. If your application has unique challenges or requirements that need to be met, our engineering team would be happy to discuss.

• Alternate coatings – If our standard powder coat finish does not meet your project requirements, we are no stranger to custom finishing; including specific paint products and colors, high performance ceramic polymer coatings, and even Rhino polyurea linings.
• Stainless steel construction – We have manufactured silencers from stainless steel when corrosion is a major concern.
• Custom connections and brackets – From metric DIN flanges and special instrument connectors to different connection layouts or special mounting brackets, we work with OEMs to produce the silencers that fit your specific needs.
• Testing – If your products must be tested for performance or air tightness, we have the ability to provide on-site testing to meet your requirement.
