This can require more pressure but nothing like prepreg or infusion. The low vacuum (20-25 inHg or so) is plumbed to a high capacity pump (40+CFM) and is used to seat bags and to hold vacuum on parts after infusion is complete. Many manufacturers recommend installing an oil mist eliminator on the exhaust to coalesce the oil mist. Piston pumps are just like piston air compressors but backwards. They dont make actual pumps but they set them up on carts with manifolds and catch-pots. 619378 The article has more in-depth information though!

Please do not copy without permission. 0000101400 00000 n Both of them were bought used from surplus dealers and for substantially under $1000 total. You dont need much of a pump here maybe 10-20 inHg and a few CFM. Some were great. Some designs of vacuum pumps contain an internal oil mist separator inside the exhaust cavity.

410643 This article discusses the options and my opinions on what the best choices are for different types of composites work.

4.) If you are a professional, here you will want the best high vacuum pump you can get and a digital vacuum gauge to monitor it. hb``a``f`c`bd@ AV haX?q*wcd4$.30H20`b*P,_D!Q)qC1S>&VW+xf230Xq1dhe``bhg1Kg`H3N &! endstream endobj 17 0 obj <>>> endobj 18 0 obj <>/Font<>/ProcSet[/PDF/Text]/Properties<>>>/Rotate 0/TrimBox[0.0 0.0 396.0 612.0]/Type/Page>> endobj 19 0 obj <> endobj 20 0 obj <>stream Backpressure can lead to leakage in the seals as they are forced backwards to their design, and in some cases can even damage or break the seals. Torr makes some crazy rugged metal sheathed hoses but I havent used them. You will need to vacuum bag some foam core and then several layers of fiberglass in epoxy resin. For small shops or hobbyists looking for a good quality pump for either high (oil) or lower (oil-less) vacuum, a rotary vane pump is a good choice. It has a switch and a handle and pulls 15-25 inHg at 1 CFM. Of course it works with lower vacuum levels (to a point) but youll have more to worry about. Better to buy three used ones for $1500 total and have two that work than to spend $2500+ on one new one and not have a backup. 1401D Includes Phenolic vanes

These pumps handle less-than-perfect bags better and provide more reliable service in a less then perfect industrial environment so ideally this is what you should get for high-vacuum vacuum-bagging. So now you want a low vacuum pump maybe 20inHg or even lower. Replacement for:

In this case, the ideal pump would be a large (30+CFM, but maybe much larger) oil-lubricated rotary vane pump. This introduces a little bit of airflow that allows the pump to vent off water vapor or other contaminants coming out of the oil.

With an oil-lubricated pump the exhaust will include oil mist if the pump is run at less than full vacuum for much time. Shaft Seal Gasket

Theyre like hammers different types and sizes for different jobs! Here you dont need lots of vacuum pressure, maybe only 10-15 inHg (500 mbar, 380 Torr) but the bag seal may not be perfect and a lot of it is overhead so youll want some capacity, maybe 10CFM or more. The rotary-vane Gast pump shown above is also nice, and it has more volume capacity but its a little noisier. McMaster Carr sells (you can also buy by the roll and have your hose-maker use this) a yellow vacuum-rated Gorilla-brand hose that works great at room temperature. 0000100213 00000 n 412962 You are responsible for your own judgement and outcomes.

Weve tested over 10,000 automotive products over the past few years so that we can show you the very best of them.

QUANTITY PART NUMBER Here is where Id recommend switching over to a oil-less (or dry) rotary vane pump that can handle running at reduced vacuum. These pumps often have an oil filter (looks like a car oil filter) and an exhaust filter, which keeps the oil from blowing out with the exhaust air. You will notice more vapor/smoke when there is more pressure. This site contains information that reflects the opinions of individual authors mostly me, Chris. Generally bagged wet layup or core bonding is the least demanding of the types of vacuum bagging. The high vacuum is used before and during infusion and can be a smaller pump, but will most likely be an oil-lubricated rotary vane pump capable of pulling high vacuum (28-29 inHg.)

1 More vacuum equals more compaction pressure and there are few reasons to use less pressure. Vane Spring And make sure you get the right oil for your pump.

Your first goal with the bag are to consolidate and clamp the material against the mold or the part youre secondary-bonding, or part youre repairing.

For room temperature use, heavy-duty air hose is fine for vacuum if youre not shooting for high performance. This is a perfect place for a small diaphragm, piston or dry rotary vane pump. Over the years I have owned more than a dozen vacuum pumps and have dealt with many dozens more that belonged to friends, customers or employers.

We can measure the amount of air removed from a vacuum bag relative to the air outside (atmospheric pressure) with a relative vacuum gauge. You wont get super high vacuum from a diaphragm pump but small ones are portable and you dont have oil to deal with. This applies to rotary vane pumps oil-less and oil-lubricated. First a bit about vacuum in general. A vacuum pump has several essential parts, and the oil reservoir is one of them.

Here are short descriptions of each: Diaphragm pumps are a lot like piston pumps except that they are often quieter because instead of a piston they use a flexible diaphragm! 0000029730 00000 n

The reason a vacuum bag presses down on its contents is that the atmosphere (air, sky, all the clear stuff up there) weighs a whole lot. They dont like having lots of air flowing through so it is best to only use an oil-lubricated rotary vane pump for very high vacuum. This is a situation where two pumps are ideal. And heres another reason to trust us: all our products come with a warranty and service anywhere in the world. One company worth looking at if you are in a manufacturing environment is Vacmobiles in NZ.
