Each situation regarding fume hoods and there usage must be evaluated individually to determine the best approach to using fume hoods to capture and filtration. Fume hoods must be designed to maintain a predictable flow rate through the face opening. The proper combination of blower capacity and hood face opening size will accomplish this. Many of our systems are custom designed enclosures. We work together with lab managers, plant operations supervisors, and health and safety engineers to determine an environment's filtration requirements. We then recommend a highly functional, worker oriented solution. Since the rise in drug discovery technology we have been provided the opportunity to put our expertise in fabricating custom enclosures to work. Over the past several years we have built many custom Laboratory Robotics Enclosures for numerous companies. We have the capabilties of working from your drawings or providing you with an AutoCad drawing to your specific requirements.
An enclosure can be: Positive Pressure - creates a dust-free work area of better than 100ppm for highly sensitive samples or instruments. Our portable clean rooms provide a particle and bacteria free work area for a fraction of the cost of a full size clean room. Units will protect product and samples from contamination with Class 100 or better clean air. Negative Pressure - designed to enclose materials and operations under negative pressure, thereby preventing airborne contaminants from escaping into the work environment. Contaminated air is drawn through a variety of filters to remove pollutants and/or particulate and recirculates clean air back into the room. Carbon Filters are available for vapors and Hepa filters for particulate. Our ductless hoods recirculate clean air back into the room. Containment Hood Only- enclosure without blowers or filtration to protect equipment from dust or for connecting to an existing ventilation system. Most Airfiltronix enclosures are constructed of clear 1/4" thick acrylic panels with sturdy aluminum framing (other panel materials are available if required, i.e. chemical resistant, polycarbonate, polyethylene etc..). Custom ports and hinged doors can be designed to accommodate your particular application.
Airfiltronix portable tabletop ductless fume hood systems are designed to enclose materials and operations under negative pressure, thereby preventing airborne contaminants from escaping into the work environment. Contaminated air is drawn through a variety of filters to remove pollutants. Filters are available for both vapors (activated Carbon) and particulates (HEPA) and they can be combined for multiple substance filtration. Our fume hoods are constructed of clear, 1/4" thick, acrylic and polycarbonate panels with sturdy aluminum framing (other panel materials are available if required). They come equipped with a clear vinyl curtain providing easy access while maintaining optimal airflow across the opening (optional door and sash configurations are available upon request). The ductless hoods can be made to order with custom sizes and features tailored to your specific needs. Blower/Filter modules are normally mounted on top of the hood, however, if space is limited they can be remotely located and connected to the fume hood via PVC hose. A high efficiency fume hood's, brushless AC motor with dynamically balanced backward curved impeller moves up to 530 cfm at a noise level of less than 68 db. If required the hood can be purchased without blower and filter units for connection to an existing venting system. Alternatively, a venting adapter kit is available for the blower to provide for both filtering and outside venting.
