Optional 316L stainless steel material upgrade available for enhanced corrosion resistance.
Acrylic
Economical Acrylic provides excellent clarity and provides high tensile strength it is damaged by frequent contact with alcohol and other common cleaning agents
316L Stainless Steel
Aseptic, low bio-burden, withstands high temperature and humidity fluctuation; low carbon rating indicates reduced percentage for enhanced corrosion resistance
Powder-Coated Steel
Durable powder-coating protects steel housing and minimizes contamination; these models incorporate filters with aluminum frames.
Polypropylene
Opaque (white) polypropylene resists most acids and bases
Static Dissipative PVC
Static Dissipative PVC: Safely conducts surface charges to ground, protects against particle aggregation, and has broad chemical resistance for easy sterilization.
Optional 316L stainless steel material upgrade available for enhanced corrosion resistance.
Corian
Corian is non-porous and chemical resistant, making it easy to clean and sterilize with alcohol and other cleaning agents.
Non-Dissipative Laminate
Cleanroom-grade laminate is sealed along all edges to prevent particle release
Static-Dissipative Laminate
Combines the chemical- and heat-resistive properties of plastic laminate with a controlled path to ground for dissipation of static charge without voltage suppression ambiguity. This laminate has a micro-thin layer of aluminum oxide (Mohs hardness of 9; diamond = 10) integrated directly into its surface, creating an extremely hard protective layer, which provides long-term resistance to surface abrasion. This material has also been specifically tested for particle trapping (see test results below.) Each sheet used in fabrication is individually certified to meet the values set forth at below.
Polypropylene
Polypropylene tops provide superior resistance to chemicals, particularly acids
HEPA filter combined wih high-capacity 2'x4'x3.75" thick activated honeycomb carbon. Carbon filter adsorbs up to 7.5lb VOCs including fumes, odors, and other pollutants.
Smart WhisperFlow models use an energy-efficient EC motor that meets low-energy regulations; allows centralized FFU flow adjustment and room pressure balancing to meet ISO requirements.
Permanent Split Capacitor (PSC)
AC fans provide low cost, reliable operation – ideal for most laminar flow hoods and small cleanrooms; unique WhisperFlow FFU baffling system ensures quiet operation
Automated system controls nitrogen flow rates to maintain RH set point across entire cabinet. Built-in dilution fan efficiently distributes inert gas to reduce recovery time after door is opened and eliminates moisture plumes or collection areas that degrade sensitive components.
Doors can be removed and autoclaved for complete sterilization
Leak-Rated
Pass-through doors with sealing integrity are leakage-rated by UL; built with unique gasket and lift latch assembly to control leakage of air and cross contamination between rooms. Ideal for cleanrooms and USP <797/800> pharmaceutical applications.
Heated WhisperFlow fan/filter modules include a heating element mounted inside the FFU housing.
Vapor-Removal & Sanitizing
Carbon prefilter removes volatile organic compounds (VOCs) to ensure a safe, clean process environment. The prefilter also helps compensate for VOC spikes that might occur during certain operations.
UV Sanitizer kills most bacteria, viruses and molds to eliminate biological hazards inside the cleanroom. It also energizes the PCO, boosting its vapor-adsorption efficiency.
Negative pressure Reverse-Flow WhisperFlow™ Fan-Filter Units remove sub-micron particles, aerosols, and fine dust generated inside an enclosure, allowing safe release of HEPA- or ULPA-filtered air. They are perfect for hoods, enclosures and modular cleanrooms that contain operations that produce particles unsuitable for exhausting into the surround space.
Positive Pressure
Positive pressure WhisperFlow™ Fan-Filter Units provide a uniform flow of microfiltered air to meet cleanliness standards down to Class 10 (ISO 4).
Ideal for frequent use applications and maximum service life. Unique non-outgassing rubber "e" shaped gasket combined with robust door latches and rigid stainless steel construction provides a tight seal and maximizes service life.
