If you overflow your job and get resin in the pot, you can bust open the base and clean it out after the resin cures or you can just leave it if its a small amount. This is really useful for bagged wet-layup where you want to limit resin bleed, and in some cases for infusion too. Use these straight plastic push-fit barb connectors to join lengths of vacuum hose. Home:Articles:Tools and Equipment: Vacuum Stuff. Contact EHRS if you are unsure how to properly vent your vacuum pump. Typically these are rated to take heat in the 150C / 300F range which is fine for most non-aerospace pre-preg work. To accomplish this, tubing must be connected directly to the exhaust outlet on the pump and routed into the hood or exhaust duct port. Locate in a vacuum pump cabinet (if one is available) or other ventilated cabinet such as a fume hood. If you dont want to spring for a fancy pot you can make catch pots from PVC pipe for about $20US each. At the left we have regular air hose fittings which can work but are meant for pressure instead of vacuum and so they can leak and give you all kinds of trouble.

All rights reserved. Some vacuum pumps cannot accommodate the type of oil-mist separator that has an outlet for exhaust tubing. This can result in pump damage. Vacuum pumps which are used to evacuate systems containing toxic, corrosive or volatile substances must be vented into the buildings exhaust system. You have to know how much vacuum you have got or how much air is not in your bag. With all those nice hoses, youre going to need some way to connect them to each other and to you pump and bag. Pipe threads are designed to get tighter as you screw them in but they also need some thread sealant to make them fully vacuum-tight. It wont take pre-preg heat but it will be fine up to 140F / 60C or so and good for post-curing.
For all systems involving potentially hazardous materials, vacuum exhaust for must be vented to a laboratory exhaust duct or fume hood. This is the knob-equipped brass item connected to the back hose. First a bit about connector types the image to the right shows five different options, and only three are really good for composites-level vacuum work! This one has two inlets the brass looking ones to the sides and a single vacuum port on top to connect to the pump. Materials, equipment and training for advanced composites. Routine maintenance such as pump-oil changes may be performed by lab workers. PVC pipe is ok, metal is better. Get one with a big enough dial to read and ideally an oil-filled one. Dont use these nice through-bag fittings for infusion because youll ruin em! My favorite of this kind is Gorilla Hose (a Continental or Goodyear Brand) which is a 500psi-rated hose and its yellow which is cool. The black hose here is a pre-made 300psi air hose with vacuum fittings instead of air fittings. So you place your vacuum fitting inside a secondary piece of 4 tube-bag that has strips of infusion flow media inside. Failure to properly vent the pump can result in contamination of the lab with hazardous chemical vapors. Connect the exhaust line to the exhaust port in the vacuum cabinet (if one is present) using a thimble connectionorrun the hose into the fume hood. Measure before you order. Philadelphia, PA 19104, E ehrs@ehrs.upenn.edu Small pumps local to different work areas are good because they are reconfigurable and provide local control over the system. For vacuum infusion, this is a different story this here applies to bagged wet layup and pre-pregs work. The Safety Alertalso provides guidance for selecting the appropriate pump for your research needs. Vacuum pumps which are used to evacuate systems containing toxic, corrosive or volatile substances must be vented into the buildings exhaust system. Dont just jam a hose under the bag without some distribution medium over the end because it will suck the bag into the hose and pop it or it will fill up with resin and choke off the flow. This is a set of 1/4 ISO 7241-B or Parker ISO-B style fittings with 1/4 NPT thread. You may need to use them to interface with pumps and filters though so they are good to now about. See SOP: Cryogens and Dry Ice for more information aboutpreventing theformation of liquidoxygen and what steps to take if you observe that oxygen has condensed. Use these push-fit plastic T-connectors to split or branch sections of vacuum hose. The exclusive offers are REAL. Ask me how I know! If the pump cannot be unplugged directly, contact EHRS for information about lock-out/tag-out before attempting to service the equipment. Keep combustibles away from pumps. The base is a piece of PVC (or metal, or something vacuum-tight) that is held on with tacky tape (yellow). Extreme care must be exercised to prevent the introduction of room air into a trap containing liquid nitrogen. A lot of time youll see fittings with vacuum bag sealant tape wrapped around the threaded connections. Use a cold trap to prevent the degradation and contamination of pump oil. Any place that makes hydraulic hoses to order can make you air or vacuum hoses too and it can be much cheaper than McMaster-Carr or your local equivalent! Belt guards must be in place for all belt-driven pumps. What kind of hose you use depends on what you are doing and what kind of conditions youre doing it in! A cold trap must be placed between the pump and the experiment to, The trap must be adequately sized and cold enough to condense vapors in the experiment. Youll just need a way to plug the unused ones. This is often the type of fitting found on high-vacuum pumps and this is one I used to interface with a Leybold pump I used to have. These are small-diameter ones, which is generally what youd need for individual parts. These can be good for cheap connections for room-temperature wet-bagged and infusion work. Lots of my fittings are like this. Keep detailed records of all pump maintenance including routine maintenance and vendor-provided services. If vacuum pumps are not properly installed, trapped and exhausted they may expose you to hazardous chemicals and vapors. Check frequently for blockage. When in doubt add some bag sealant tape! Both PTFE tape and liquid thread-sealant work ok. Brass fittings are nice because they are softer and less likely to corrode and they are cheap.
You also want to be sure to remove them from the bag before disposing of the film too many of these get thrown out by mistake. Pumps for rotary evaporators must be located in a fume hood, vent to dedicated lab exhaust, or be equipped with adequate condensers and traps to prevent emission of solvent vapors into the lab. They are secure and when you get ones that are rated for it can handle vacuum very well. This is a great way to handle situations where you dont have room for a fitting under your bag. The sketch shows my basic design which is far from perfect but worked for me. For larger hoses, cam-lock style connectors (far right) are a good choice. Follow all manufacturer recommendations for oil changes and routine maintenance. Maintain trap during the experiment. It will handle low pressure autoclave use too. Moving up to a more permanent solution, we have the rubber coated air-hose style black hose. Youll want an in-line gauge to see what your vacuum is as you adjust the dial. Infusion is all about vacuum as much as possible in many cases. General purpose vacuum fittings in 1/4" and 1/2" BSP threads (the same as 'G' or 'Gas' threads in Europe) can be used to connect vacuum pumps and vacuum equipment in a wide range of configurations. The best solution in my opinion is either several cell or station-specific vacuum pumps (ideal) or a larger factory-wide vacuum system. These are called: plates, frogs, vac. Easy Composites Ltd, registered in England 7486797. do not use hydrocarbon pump oil with oxidizing gases or vapors) with the vapors that will pass through the pump. Place the pump on a tray so that spilled oil is contained. See and test specialist products in our on-site demo room. Be safe! If you look at very high vacuum systems used in lab / science / fancy industry work youll see these are the standard for vacuum. This fan helps remove excess heat from the pump cabinet. Finally the simplest vacuum connection of all that big curvy guy at the right a hose with something wrapped around the end and a quick connect fitting on the other. I see lots of people use this for infusion and it is a poor choice at least for the vacuum side. If you find yourself doing pre-preg or infusion at any commercial level, a digital gauge will really give you a better feel for whats going on especially an absolute gauge. All content copyright (C) Easy Composites Ltd, 2022. The vacuum port connects through another hole, so resin will drip into the pot and air will pass through to the vacuum pump free of resin. Pre-pregs bring high heat to the mix and potentially lots of extra pressure in an autoclave.
You can make one with only one inlet or more than two. My goal is not to tell you exactly what to use, but to show you what I use and explain why, and point out the key ingredients to successful vacuum systems. This is the low-end of autoclave hoses and fancy metal ones are available that handle up to 1000psi of pressure and 1000F / 500C. P (215) 898-4453 It reads vacuum relative to absolute pressure, so it is not swayed by the atmospheric pressure. The pump may not vent into the cabinet interior.

You can put a paint pot inside to catch any resin that flows in. You can use it in disposable fashion, but it can also be fit with barbed or push-to-connect (shown) fittings and made a more permanent option. Vacuum pumps must be serviced by an authorized vendor on the schedule recommended by the pump manufacturer. You can use heavy gauge PVC in large diameters and have they vacuum plumbing be the accumulator!
This one has a gauge and a small regulator on it and was sold by Airtech. ], Need any help or advice?+44 (0)1782 454499. Liquid Nitrogen condenses oxygen and this may cause an explosion.
