Nanotechnology continues to advance in a variety of industries, including aerospace, research, pharmaceutical, and academia, yet few effective containment solutions for particles that range in size from 1nm to 100nm exist. The Purair® NANO enclosure is designed to contain nanomaterial particles that are 100nm or less in diameter (ultra fines). With a stainless steel infrastructure, powder coated FFU, and dual filtration options to ensure superior containment, the Purair NANO provides a safe work environment at an affordable price.
Purair NANO Features & Benefits
- Protects the operator from nanomaterial particles (less than 100nm in size) encountered during processing of carbon nanotubes, lithium batteries, and rare earth metals. SafeSwitch™ Filter Shutter System (optional) for safer bag-in/bag-out filter exchange.
- Innovative filter clamping eliminates bypass leakage.
- Exhaust canopy allows for thimble ducting to the facility exhaust system.
- Airflow monitor with low airflow alarm built-in.
A. Filter I.D. Window: A strategically placed front cover window shows the installed filter part number and installation date to encourage timely filter replacement.
B. Glass Side Panels: (Optional) Purair NANO hoods are available with glass side panels which allows greater visibility and ambient lighting into the work area.
C. Rear Internal Baffle: Rear baffle provides smooth horizontal airflow pattern. Removable for easy cleaning.
D. External Exhaust Connection: Standard 6 in. diameter exhaust connection port to allow for outside ducting.
E. Built-in Lighting: Hoods include standard 60W lights to fully illuminate the work surface.
F. Air Velometer: (Optional) An analog air velocity meter in the field of vision of the user.
G. Hinged Front Sash: When closed, the cabinet sash protects the contents from inadvertent external contact, and better isolates the air within. The sash is easy to open and close and features a self-locking feature.
H. Control Panel: Electronic controls and displays include switches for the blower and low airflow alarm. Ergonomics, safety and aesthetics all come together with the 10° pitch of the face.
I. Stainless Steel Support Frame: The 304 grade stainless steel provides excellent strength and chemical resistance and is cleanroom compatible. The satin finish enhances illumination.
J. Electrostatic Pre-Filter: The 99.5% effective electrostatic pre-filter is accessible from inside the chamber to contain the release of any particulates that it traps. The pre-filter can be changed while the unit is operating to prevent operator exposure to chemical vapors.
K. Pass-Through Ports: Electrical cords and cables are safely routed into the cabinet through 1 5/8" diameter ports on the back and side walls.
L. Airflow Alarm: A continuous air velocity monitoring system alerts the operator upon unacceptable values.
M. Built-in Blower: All models include an internal blower. The powder coated metal fan filter unit withstands tough environmental conditions. The addition of an optional remote blower and additional ductwork allows the cabinet to be connected to an existing facility exhaust system.
N. Internal Manual Speed Controller: Authorized personnel may set the centrifugal fan motor speed as desired.
O. Stand: Optional mobile cart with locking casters.
P. Work Surface: The epoxy resin worktop has excellent chemical resistance and spill retention.?An optional stainless steel worktop is available; see Accessories.
Q. Filter Door Key: Filter access keys prevent unauthorized removal or accidental exposure to dirty filters.
R. Construction: (Optional) All polypropylene construction is available if desired; see Accessories.
SafeSwitch™ Filter Shutter System:(Optional) A unique filter shutter system closes the exposed filter media face and minimizes exposure to the contaminated filters, protecting the operator and the environment.
The Purair NANO Series ductless nanoparticle enclosure maintains a constant face velocity of 100 FPM in compliance with USA and international standards for safety and performance. Contaminated air is pulled through the Multiplex™ filtration system and clean air is returned to the room.
A. The main filter is easy to replace, no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and maintain filter integrity. The optional SafeSwitch HEPA Filter Shutter system also ensures that operators are safely separated from trapped contaminants during filter changes.
B. Exhaust is thoroughly scrubbed of nanomaterials produced from actions within the hood.
C. Choose from HEPA (ULPA optional) or activated carbon. If HEPA/ULPA is chosen the cabinet can be used without connection to an outside exhaust.
