Glen,
You might consider a Universal Silencer (brand name). Here is a brochure.
The probable closest crossover to what you have is the SD series (# SD-2). You may find that this size is a tad small for the CFM you are running, and may want to consider a larger size. I am supposing however that your reason for posting is that you find the existing price a bit exorbitant. However, Universal's offerings are going to be comparably priced.
Some users have found alternative types (not designed for PD blowers at all), mainly for automotive engine applications, to be "satisfactory". To each, his own I suppose. The truth is that for the particular sound characteristics of a roots-type blower, the combo absorptive/reactive silencers, tailored for the resident frequencies, are most effective. That is why Stoddards, Burgess Manning, and Universals are so common.

We only use Stainless for blower silencers.
I've seen too many rust clogged OEM silencers to rely on them any longer.

IMO the automotive type silencers(mufflers) don't do the job if your turning the blower anywhere near optimum speeds. I've tried on and two mufflers in several configurations and have not been happy with the results. Get the Stoddard/Universal type silencers, even at the higher cost. Just wondering why you need a replacement? These things last a long time if you not sucking a lot of water thru them.

We used to use a quality flo-thru Automotive muffler (ss) and had absolutely no problems. You might want to look into those at a local store...........................

ya ...i jus woke up...thought i'd get up a little early today....my silencer is the old Steam Genie one off a 45..no holes..just rusty!
ya those 3' Flowmasters worked good if you welded up one end shut and cut a 3' hole in the side...no straight thu sound..but ya HAD to have TWO....to knock the top AND bottom off the sound sine wave....the stoddard is straight thru wit a lot of baffles...

We tested many different silencer db levels . . . . View attachment 5223
before deciding on the stainless models we use now.
FloMaster did not make the cut.

Bob, you must have some serious OCD because that dual set up on your old Steam-Genie 47 was awesome. I loved the way you had one of the FloMasters off the vacuum blower and another underneath the van after the 90* elbow on the blower exhaust. Man alive, that was so quiet, I kept looking at the RPM gauge in disbelief, couldn't believe a 47 blower could sound so subdued.

Glenn;
It is available in 2.5" ID , which is actually 2 5/8" O.D.
We would add these 2 items to fit to 2" pipe :

Plus a secure clamp :

Even without knowing how your machine is configured/installed/vented I can tell you with confidence that a double walled dual chamber blower silencer will give you the maximum suppression you may be looking for. I've messed with this for almost 10 years with 3 universal silencers and probably a dozen automotive mufflers (funny how truckmount manufacturers call them silencers). If I state here the actual decibel numbers comparing silencers with mufflers the b.s. around here will stack up faster then can be shoveled. However I will say look at your configuration with all its measurements and attempt to find a Universal brand blower silencer that fits the cfm flow and inlet/outlet pipe dimentions.

I have spent 1000 $$ over the past year trying to find blower silencers for my 2 naamco's....been thru 3 and they are some kinda messed up loud mufflers.....don't work...I don't trust any thing that even looks like a muffler...I have 4.5 blowers
The original silencers rusted over 10 years and namco in houston only has mufflers,!
I may look into these stodard silencers Or any others who can tell me where to get a good solid silencer
Thanks

Looking around the garage yesterday I found 3 silencers of various sizes. All 2 inch openings. They don't look like they have been used. They are for sale cheap. Anyone need a 1 million btu furnace or heavy duty shop carts. I have about 10 of those I need to get rid of.
