ventilation and air quality view from below of ventilation ducting in a factory space requirements ventilation equipment is not provided by carbon and can be a long lead item therefore, planning and installation should be started early in the site preparation process you must have either built in mechanical ventilation or a stand alone unit that meets the requirements below before scheduling your printer installation item flow rate requirement additional requirements m1 / m2 printer minimum flow rate 34 51 m³/hr (20 30 cfm) per printer printer exhaust outlet 4” diameter exhaust on the back of the printer m3 / m3 max printer minimum flow rate 34 51 m³/hr (20 30 cfm) per printer printer exhaust outlet 4” diameter exhaust on the back of the printer post processing area 85 m³/hr (50 cfm) per wash area adjustable snorkel or fume hood optional fp3d requirements for customers that will use fp3d (pre release access) docid\ u cqe4ai3bbu3avcjqwlo resin, a thermal curing docid 7ne6rgdaszpapohh5qozm is necessary see facility requirements below item flow rate requirement additional requirements convection oven 34 m³/hr (20 cfm) per oven convection oven exhaust outlet 4” diameter exhaust on the top of the oven high temp hose convection oven ventilation example your onboarding consultant will ask for a picture of each ventilation connection before scheduling the installation we recommend a central line central line of ventilation with multiple drops multiple drops , each with an installed blast gate blast gate rear view of oven with adapter additional oven ventilation notes your oven is equipped with an adapter adapter to ensure flow rate is not too high please attach the oven to the ventilation system using the provided adapter, which is shipped inside the oven the adapter is a flanged ventilation duct with an outer ring held with three wing nuts that should be installed on top of the oven you should connect it to the oven first so you can easily connect it to your 4 inch round exhaust duct do not seal the outer ring (a common customer issue) this arrangement pulls air from the room rather than sucking heat out of the oven, but in doing so also removes oven fumes as oven exhaust temperatures can exceed 220 °c , use metal duct or metal duct hose metal duct or metal duct hose , plus a hose clamp, to withstand the high temperature air for at least 10 feet to allow for sufficient cooling you can also use a flexible hose with a high temperature rating, such as the silicone hose from mcmaster carr once the oven has been installed and ventilated, please conduct temperature checks, using any precision oven thermometer , at 60, 120, and 220 °c to ensure your oven is maintaining the proper temperature facility air quality printer must be installed away from sources of particulate matter smoke, dust from grinding, milling, sanding, or polishing, or any other known sources of dust or air contaminants (internal optical equipment is highly sensitive and will degrade when exposed to significant pollutants) room where printer is installed should have air filters to maintain air cleanliness above requirements do not apply to post processing areas ventilation options stand alone units (fume extractors) built in mechanical ventilation for other questions about your specific ventilation situation, contact the onboarding team total ventilation capacity the minimum ventilation requirement for a single m1 / m2 or m3 / m3 max printer lab plus the post processing area is 119 m³/h (70 cfm) building capacity for plenty of ventilation is a good idea for your carbon lab because excess ventilation will make it easy to accommodate more printers and adopt future products or accessories without the need to re engineer your lab faqs and additional information how do we know if our installation site has adequate air quality? for most installation sites, air that is filtered and clean enough for workers not to wear dust masks will likely be adequate in addition, the printer must be separated from any machines that emit smoke, dust, mist, or particles for additional assurance, air particle counts may be tested to meet iso 8 classification, which provides acceptable particle limits for carbon printers what are the ventilation options available? there are two options to consider when planning ventilation for your printer either option must meet the following requirements mechanical ventilation mechanical ventilation is the intentional fan driven flow of outdoor air into a building mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of the building and thereby cause equal ventilation flow into a building), or a combination of both ductwork is required along ceilings and/or walls to create the pathway for air to be vented to the outside of your building if you don't already have a mechanical ventilation system, you may need to consult with a contractor about building such a system for your lab mechanical ventilation is a long lead time item if you choose to proceed with mechanical ventilation, carbon recommends that you begin this step early in the site prep process stand alone ventilation or fume extraction a fume extractor has two flexible hoses to accommodate up to two locations (the printer and the post processing area) fume extraction costs less than mechanical ventilation and is easy to install if you have questions about ventilation, contact the carbon onboarding team can i use a stand alone ventilation system (fume extractor) instead of mechanical ventilation? yes, most dental customers purchase a fume extractor instead of installing mechanical ventilation to meet the site prep requirements however, there are several instances in which you cannot use a fume extractor the fume extractor is not compatible with the following non dental resins (carbon 2 part engineering resins) any oven other than a uv cure unit multiple m series printers (you will need more than one fume extractor) for more information on fume extraction, contact the carbon onboarding team what are the trade offs between mechanical ventilation and stand alone ventilation? installation of mechanical (traditional) ventilation is costly and time consuming however, it is a more effective option if you are currently using or plan to use multiple printers or additional equipment that requires ventilation the fume extractor is recommended for single printer sites that do not plan to add additional equipment it is relatively low cost and will meet appropriate health and safety requirements carbon has validated the following stand alone ventilation system sentry air systems model # ss 400 fsd do i need a contractor for traditional/mechanical ventilation? in most cases, you may want to use a contractor to install mechanical ventilation a contractor can help ensure that your ventilation system meets all local and regulatory codes, as well as carbon recommended specifications why does carbon have a ventilation requirement? carbon printers require ventilation because liquid resins and solvents are classified as hazardous materials without ventilation, your facility could be exposed to fumes that could pose a health risk for your employees for more information regarding health and safety, contact your local regulatory agency electricity power plug in a wall socket in a lab requirements you will be required to supply power to the following equipment and accessories m1, m2, m3,
