Dust Doctor B onding and grounding of dust collection system components is a critical step if you handle combustible dust or powder, meaning that the dust can be ignited when dispersed in the air in a sufficient concentration. In general, static electricity can ignite a combustible dust cloud if the minimum ignition energy of the dust is very low.
Keep your shop and your workers safe with metalworking dust collectors from JET. Quiet, easy to use and set up, dust collection is a must in any metal shop. Trust JET to handle the dust collection so you can focus on the work ahead of you.
Dec 11, 2008 I have read several articles on the pros and cons of using metal instead of PVC piping for dust collection systems. There are also articles stating that grounding and bonding PVC does little good in the effort to prevent static discharge.
Here is an example if instruction from Shop Fox, a popular portable dust collector manufacturer. System Grounding. Since plastic hose is abundant, relatively inexpensive, easily assembled and air tight, it is a very popular. material for conveying dust from woodworking machines. to the dust collector. We recommend using flexible hose
Design-Your-Own Dust Collector Duct System. Use these components (sold separately) to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations. Hose clamps are available. For maximum safety and to avoid a dangerous buildup of static electricity, you must use the grounding kit (sold ...
All dust collection systems build up static electricity, and if not grounded, that electricity could become a hazard that could start a fire. Our grounding kit provides everything you need to ground a dust collection system, including directions for installation. A large system may need more than one kit. Kit includes 50' of 14-gauge bare copper wire, electrical connectors, grounding screws ...
Jan 26, 2017 To ground your dust collection piping system, run your wire along or around the pipe throughout the system. This gives a place for built-up static electricity to be dispersed. At joints, you should either provide extra slack wire or install bayonet connectors. Attach one end of the wire to the metal housing or frame of the dust collector itself.
Run a ground wire along each branch, and splice each into the main wire. Connect the ground wire's conductor to the dust collector's metal frame or housing. The other end should extend to the outlet port on the tool, but it doesn't need to connect to anything, except to keep it in place. (Think of the wire as an antenna rather than as a ...
Connect the wire to a surface that is connected to a grounding electrode conductor system of the building. This may include a grounded metal pipe, grounded junction box, grounded wire or any equipment grounding electrode. The wire should also be grounded to the equipment connected to the duct work (i.e., the tool and the dust collection unit).
Apr 12, 2009 Dust Collector Grounding Question. I’ve never posted before, here or anywhere. I have a question about grounding a poratable dust collection system for a small basement shop. I’ve read that if using PVC, one must ground both the inside and outside of the pipe. Makes sense. If plastic fittings are used in metal ductwork system, jumper around ...
Mar 05, 2014 At my shop I use PVC for my dust collection and have installed grounding wire warped around the pipe and taken to a single point of ground. In our training and system configurations we only use a single point of ground and not multiple points of ground to keep form having a different ground potential, with multiple grounding points “Different ...
The dust collection ductwork is the hose and wand that draws the dust away from the machine creating pollutants. And the dust collector is the vacuum cleaner filtering dust and returning clean air either to the building or outside. Helps eliminate the risk of fires and possibly explosions, created by the buildup of “combustible dust”.
Jan 19, 2011 A Dust Explosion that begins in the Dust Collection System can lead to the destruction of an entire facility. Most solid organic materials, in addition to many metals and inorganic nonmetallic materials, when reduced to a finely divided size, and sufficiently dispersed into the atmosphere will explode under the right conditions.
Fire prevention systems are designed to remove ignition sources, before an event occurs, through the following means: Spark Detection and Extinguishing Systems – Infrared sensors or detectors are placed in the ductwork upstream of the dust or fume collection equipment to sense a spark or burning material and extinguish it with a minimal amount of water before it becomes an ignition source.
Oct 06, 2015 As a SERIOUS hobbyist wood worker, I run a 1 1/2 hp dust collection system in my shop with dedicated ducting to stationary tools including the XC and I don’t run grounding wire. I can get a bit of a jolt from my drum sander’s DC hose while in use but never enough to generate a spark
The dust is in contact with the grounding for only a fraction of a second, even in a metal pipe. You will remove very little charge from the dust. 8. Metal ducts keep the dust from charging. Dust charges perfectly well in metal ducts. Grounding metal ducts keeps the ducts at an equal potential so you don't get metal to metal sparks.
With a metal dust collection piping system, static electrically won't develop. Elbows and other various fittings are properly designed for conveying dust. The diversity of fittings and accessories will enable you to meet design requirements.
Jul 31, 2013 2. The AMS is not used to vent or serve metal grinders, hot work processes, or machinery that can produce sparks. 3. The AMS is not used to vent or serve sanders, abrasive planers, or similar sanding process equipment. 4. Each collector system has a maximum air flow handling capacity of 3000 CFM (1.4 cu m/sec). 5.
Aug 15, 2016 Most dust collection companies that sell plastic parts also sell a grounding kit. Make sure to follow their installation directions to the letter, and use a continuity tester or a multimeter to verify that the ground circuit is in fact continuous. To prevent leaks, use silicone to seal any holes you drilled into the pipe for the ground wire.

Jan 14, 2018 When I put dust collection on the grinders in the metal working area, I used both spark arrestors and cyclones before the fans, and had flame retardant MERV 15 cartridge filters custom made. A spark would have to make it through the arrestor and the cyclone to start a fire in the collection bin, or go through the fan and into the filter plenum ...
Jul 16, 2012 Dust Collector. The heart of any dust management system is the dust collector, and Delta was kind enough to send me the Delta 50-786. This unit features a 1-1/2 HP induction motor, 1 micron filtration, and 1,200 cubic ft. / min (CFM). It can accommodate two 4″ ports or one 6″ port.
Static electricity requires grounding a dust collection system which is why Air Handling Systems pro-vides galvanized metal spiral pipe and fittings and flexible hose with wire helix. A plastic or PVC pipe system cannot be adequately grounded. National Fire Protection Association (NFPA) requires pipes and duct be constructed of metal and be grounded and that non conductive pipe or ductwork should not
Matt, the main purpose of grounding a DC system is to avoid electrostatic discharge & effects. Body discharge is annoying but very minor. The effects might be even worst for some people, where your body hairs raise when too close. Some people are more subject to electrostatic.
Jun 30, 2013 Promptly turned it off and installed a grounding wire. In the new shop the main dust collection trunk line is 5″ 26 gauge galvanized duct, but the branches leading to the machines are mostly 4″ PVC tubing. I carefully fed bare copper wire (supplied by Lee Valley for this purpose) through each of the plastic ducts and attached it to metal at ...
Feb 01, 2010 Grounding provides a path for this excess charge to flow harmlessly to the earth, which is why dust-collection systems in all commercial shops are required by code to be grounded. However, an insulator is a very poor conductor of electricity.
Should you ground your dust collection system? Whatever the risks of explosion or fire, taking a better safe than sorry attitude and equipping your PVC ductwork with a grounding system will at least prevent you from suffering a nasty zap when you brush up against a dust collection port.
I’m finally getting around to grounding my 20' length of dust collector 4 flex hose. I’ve read to use a bare stranded copper wire, 16AWG, and that antenna wire will work too. The only problem is I can't find any bare stranded wire in San Diego!
Feb 25, 2011 I'm with Greg. I use a flexhose that has a metal slinky inside the plastic hose; I poked through from the outside to tie a ground wire from the slinky to my DC then wrapped a ground wire around the metal trash can I use for the dust. I only did it because whenever I'd walk by either, you'd feel this static draw on your skin.
