Big compressor filter silencer

[thinktwicez71]

So I got a saylor beall 4500 pump compressor dirt cheap ($100) , I got the new single phase motor and it's almost done . The only thing is it's missing the filter silencer . It's about 2" npt fitting . The previous owner had it in a machine shop and the intake air was plumbed into it from outside . So my question is for the sake of quietness should I also plumb it outside in my workshop eaves , or get a solenberg silencer for it ?

Even mounting the filter on a section of pipe will quiet it down i bet. Years ago we had these tools that had air motors and the exhaust port was open to atmosphere. They were loud as hell. I took like a 20 foot section of air hose and screwed it to the exhaust port and it was so quiet you could just hear the shafts turning.

Would pvc pipe be ok since it's lighter ? If I piped it outside and attached a filter on it outside .

And will a clamp on auto air filter work? Or should I still get the Solberg silencer and just attach that outside

What do u do modify the muffler to put a filter on it also ? Doesn't this need to filter the air coming into the compreasor as well ?

Question regarding plumbing to the outside-
Wouldn't there be a lot of condensation, meaning a lot more water in your tank, when sucking cold NY winter air into a hot compressor?
Maybe not a concern, but would like to hear from anyone with experience doing this.

"Wouldn't there be a lot of condensation, meaning a lot more water in your tank, when sucking cold NY winter air into a hot compressor?"
Just the reverse. Temperature of the compressor is not a factor as to moisture.

Once your temperature hits freezing condensation is basically a none issue, the closer to 32°, the less moisture the air has. Also with lower the temp, the more dense the air gets, the more efficient the compressor gets.

Personally I would plumb for outside air intake. If you do use inside air, use the Solberg silencer filters, added mufflers do very little to reduce sound. On my units, I use 2 Solberg filters (double the recommended size) off a Tee setup, runs quieter, filter maintenance is extended.

I'm interested as well , but for some reason I feel like on a hot humid day there would be more moisture in the air than on a cold winter day . Plus by the time the air got through the pipe that was ran in the building to the compressor I doubt it would be freezing cold . But yes I'm interested to hear people's thoughts on this

Thanks for clarifying.
I knew the humidity level of the outside air would be low, but just wondered what would happen when the cold, albeit dry, air was introduced to the hot compressor.

 

[pcmeiners]

On a hot humid day, the air is loaded with moisture, if your garage is not A/Ced, it will likely have more moisture if it is as hot as the outside, even if somewhat cooler the humidity will still be close to outside. So for the spring , fall and winter, the outside air will have less humidity then inside the garage (generally) due to moisture coming through the concrete, off human bodies, wet cars, wet wood etc.

Double Solberg setup,

You should be able to but a complete filter assembly for that machine. Any brand will do, you just have to adapt to the correct thread size. Solberg makes inlet filters for a lot of manufacturers. You can mount the filter outside if you'd like, just keep it out of the rain. Keeping the filter outside will cut down the noise of the machine by quite a bit.

Try one of these filters: https://www.solbergmfg.com/ViewProductLineList.aspx?FamilyId=1

What's the difference between a fs-31p-200 and a f-31p-200 ?

I thought fs meant filter silencer ? Maybee that's why the one that's 88 was more cause it is the fs version and the one u sent me is f only ?? Any idea

Just looked on their website , I was correct. The FS version is their filter silencer line and the F series is just a filter , no silencer built in.

I didn't notice the "F" vs "FS" difference.....

The campus where I work has many air compressors. Some for equipment and some pneumatic HVAC systems. They run, as needed, 24/7. Some the old, leaky HVAC systems cause their compressors to run a lot.

Most of the compressors have the intake plumbed to the outside of the buildings. It REALLY cuts down on the noise the unit makes inside.

Sorry I don't know what kind of housings/filters are used. They are a louvered metal dome with a replaceable filter cartridge that threads onto the pipe from the intake of the compressor.
The compressors all have automatic drains and are maintained on a schedule with filters and oil changes. They do not seem to mind outside air as there are no premature failures.

No worries, I appreciate you trying to help tho .

before dropping big money on a silencer, why not try it as is? yes, pvc would be fine to extend and an automotive filter is also fine.

 

[malibu101]

If you go outside, or anywhere remote from the compressor---
Keep that 2" the whole way. You don't want it sucking through a straw.
Forgot to mention above that the units at work are all 1.5" or 2" intake pipes.

And yeah, my opinion is as mike93lx, PVC is OK for this.
PVC and a compressor together.? The world may explode!

OK, another question for the folks with more experience.
If I personally were to run an outside air intake to my compressor, I would be looking at 30' to 35' with at least 4 90* bends due to the location of my compressor, and the fact that otherwise the intake would have to come out of the front of my house. Not an option. Not going to move the compressor, plumbing, built in storage, electrical, etc. not moving it. I'm already half deaf, so it doesn't bother me so much except it's hard to hear the stereo or tv while it's running.
Is there a concern with running the intake plumbing too far or should it be upsized running so far?
