The level of containment is dependent on a few variables: Quantity of the substance you are using, the frequency of use, and the Standard Operating Procedure you are using. Many of our enclosures contain below 1 µg/m³. See the performance page below for surrogate powder testing results:
Yes, you can! In order to receive your containment solution sooner, a 25% expedite fee is required. This will take 1 to 3 weeks off the delivery time.
Many times, users forget to plug the enclosures into the wall. Check to make sure this step is complete. If your fan is still not working, please refer to your manual and contact us.
The correct filter is determined by your application. Most applications use HEPA filters, however, some do require carbon or ULPA filters. Contact Flow Sciences for specific help regarding your enclosure.
Some broken parts of enclosures can be fixed. Flow Sciences can help you decide if your enclosure is repairable.
There are many factors that determine if your Flow Sciences enclosure is working properly. Problems with your HEPA filter, exhaust system, cross currents, and other possibilities can tamper with your enclosures ability to work properly. Contact Flow Sciences for further assistance regarding your specific enclosure.
The Certification Guidelines and manual are helpful tools to further understand your Flow Sciences enclosure.

It is time to change your filter(s). Contact your certifier if you have not already.
When the enclosure is first set up and certified for use, take the reading on the gauge and record it. When the reading doubles, it is time to change the filter.
To determine what filter is needed, we will need the serial number from your enclosure:
On the left outside wall of the enclosure near the back lower corner (near the black base). The fan housing or filter serial number does not give us the same information as the enclosure serial number, so be sure you give us the enclosure serial number.
The serial number refers us to the date of manufacture and the original order. If we know when the unit was built, we can look at the correct revision of the engineering drawing for that period of time. This is extremely important as slight design improvements are made occasionally.
This depends on what the operator is working with so that the correct filter can be recommended. For example: powder, vapor, etc.
These alarms work like a hotwire anemometer to measure air flow in the plane of the front opening of the enclosure (in most cases, where you put your hands in below the door). This safety feature assures the operator is working within the recommended air flow range.
USP 800 is a standard for pharmaceutical compounding that is done in local pharmacies. The requirements depend on if you are using hazardous or nonhazardous products. All USP800 is non-sterile compounding. If the user is working with non-hazardous compounding, then you are required to have a single HEPA system that recirculates back into the room. However, if you are working with hazardous compounding, it has to be done in its own room. The room has to be under negative pressure with 12 air changes per hour. The Length times Width times Height gives you the cubic feet of the room and you would multiply it by 12 and that will give you the cubic feet per hour that has to be recirculated. This may be accomplished by house exhaust or if the room is small enough it can be accomplished by our hood. You can have a single HEPA unit connected to house exhaust and exhausted out of the building or you can have a double HEPA unit that recirculates back into the room. All of your hazardous materials (raw drugs) have to be stored in the designated hazardous room separated from the non-hazardous drugs/room.
It depends. We would have to know the model number and serial number of the enclosure. If it is a 2000 series EVA that has a remote blower, it depends on the configuration. Upon verification of the model and serial number, we can either do the conversion kit to convert a single HEPA unit to a dual HEPA unit. Or, they would have to connect to house exhaust. Or, they can buy a new fan housing that is dual HEPA. For top mount there is no way to convert a single HEPA to a dual HEPA. So, they can either exhaust out or buy a brand-new unit that is dual HEPA. And, they can use the single HEPA for non-hazardous compounding.
Yes, we have done extensive surrogate powder testing and have available testing data. We can share those results on an independent basis. Keep in mind all testing is specific to the style of hood and application. Start here : https://www.flowsciences.com/performance/
Yes, we can work directly with a client or through distribution. We will customize the hood to the client’s specific application, equipment, and process. For more information about our process please visit https://www.flowsciences.com/about/
Yes, we have an extensive standard product line of both bench mounted and floor mounted fume hoods. We also have the capabilities of doing custom fume hoods per the customer’s specifications.
Do not unplug this alarm. A common cause is the alarm was never calibrated. Contact Us at 1-800-849-3429
A qualified technician uses an anemometer to set air flow and calibrate the alarm. There are 4 screws holding the face plate on the alarm that have to be removed. Under the faceplate, there is a circuit board which has a set button and a delay button. The set button is for the low air flow point. (If air flow drops below this point, the alarm will sound indicating it may be time to change the filter.) Once the set point is established, the delay point should be turned out to the full 30 seconds. This allows the user time to open the door to put equipment in or take it out without having to hear the alarm. Once the set point and delay point are set, replace the cover on the alarm. Then the air flow should be increased for the operation point. Optimal performance is 75 linear feet per minute, plus or minus 5, for operation.
Please contact us and we can check this for you.
Each enclosure is made with a base air foil sometimes referred to as an “arm rest”. However, the air foils are designed to improve air flow, not to be used as an “arm rest.”. If your air foil is acrylic, and breaks, we offer an anodized aluminum retrofit kit to replace the broken air foil. We will need the enclosure model and serial number. We will also need to know if the alarm you are currently using is the FS1645 or FS1650.
We have installation manuals that come with our enclosures. They are not difficult to put together. We are here to help and are happy to answer any questions that you have.
The optimal air flow is 75 (+ or – 5) feet per minute for optimal performance. For more information, please visit:

Through built to order engineering and manufacturing, Flow Sciences will use the proper materials for your application. These materials can include steel, plastic, glass, and other materials necessary to contain your applications.
Materials of construction are dependent on what is being contained or protected for the application. Flow Sciences takes a lot of pride in recommending task specific enclosures to contain the application to the best of its ability. Materials are recommended based on information we receive and what is being used inside the enclosure, so please contact Flow Sciences with that information.
