This versatile laminar flow hood gives you a particle-free work environment on any available work surface.
Portable, economical system converts any benchtop surface into a laminar flow station
Low-energy, electrically-commutated fan motor (ECM) reduces operating costs and enables remote, automatic monitoring and control of FFU (sold separately)
Provides air flow speed 109 feet/minute (0.55 m/s) measured with HEPA filter; internal baffling plates and anodized aluminum diffuser panel ensure uniform air speed across the work area
Quiet operation: 50 dBA measured 12" (305 mm) from filter face
Select vertical or horizontal flow configuration to meet your requirements
Available with many application-specific wall panels, including polycarbonate, static-dissipative PVC and stainless steel
Work surfaces available to meet any cleanliness requirement
Standard widths to 72" (1829 mm), with 24" (610 mm) or 30" (762 mm) depth (for horizontal laminar flow hoods, add another 13" [330 mm] for rear-mounted fan/filter unit)
Standard outside height of 40.8" (1036 mm); horizontal flow hood height is 24" (610 mm)
Horizontal Flow Configuration: No. 1688-93-48-SD with static-dissipative PVC Panels
Select the panel material for your application. Polycarbonate wall panels afford full visibility of work in progress and resist a broad range of chemicals, including cleaning agents. Static-dissipative PVC panels provide broad chemical resistance and prevent the buildup of static, making it ideal for processes involving delicate electronics or powders that are prone to clinging to surfaces. These panels slide into an all-stainless steel frame that provides
durable support for the Fan/Filter Units (sold separately). The stainless steel-walled hood is built as one solid piece of stainless steel (no
separate frame), offering the highest cleanliness and durability.
Each model also includes recessed LED lighting and a hinged access shield that increases air speed by restricting the air exhaust. Hood orders are shipped completely assembled, ready for operation.
Specify hood panel material by adding the appropriate suffix to the part number of the desired hood size and configuration below. The price for a hood of a specified size and configuration is the same, regardless of non-FM 4910 panel material selected.
-SD for static-dissipative PVC (panels and sash)
-PC for polycarbonate (panels and sash)
-SS for 304 stainless steel (with static-dissipative sash)
-AA for amber acrylic (panels and sash)
-BA for black acrylic (with clear acrylic sash)
-WA for white acrylic (with clear acrylic sash)
These fire-rated materials are available at the specified upcharge:
-FP for FM 4910-rated polypropylene (panels and sash): add 50% to price specified below
-FV for FM 4910-rated PVC (panels and sash): double the price specified below
Please note the following:
Fan/filter units are sold separately; refer to the tables below for configurations and pricing
All models incorporate a sash of the material specified above

Smart WhisperFlow Fan/Filter Units
Low-energy electrically-commutated (EC) fan/filter units comply with energy-efficiency standards such as California's Title 24 and the European Union's ErP 2015 Directive. Their brushless 1/3-HP DC motors have internal
micro-processors to enable remote monitoring and control (such as off-hour energy-saving
mode). ECM FFUs produce lower heat, vibration and decibel levels than
mechanical AC motors. At medium setting (2"x4" model), the FFU uses 280W/2.4A power at 1000 RPM.
Vibration-isolated work-surface stand with free-standing hood frame isolates vibrations caused by the hood blower
Two-piece design separates WhisperFlow Hood from sealed laminate top work surface to isolate fan vibration (order both a work surface and a frame unit from the table below). Adjustable model height range = 25" to 32": height adjustment in 1" increments.
*Includes ionizing bar, power supply, and installation kit; Ionizing kit and FFU must be ordered together.
Vapor-Sealed Fluorescent Illuminator This fluorescent light fixture is enclosed in a vapor-sealed static-dissipative PVC housing. Price includes installation. Be sure to select a length that fits inside your enclosure. Operates on 120VAC or 220VAC (50/60Hz).
Vertical vs Horizontal Laminar Flow Things to consider when deciding between vertical or horizontal flow. There are advantages and disadvantages to each airflow direction and hood design, depending on your application and laboratory lay-out.

Airflow Uniformity and Fan Filter Units Fan filter units help to remove contaminants from controlled environments. They are effective if designed well. Variables like speed and baffles contribute to an FFU's ability to maintain uniform air speed and direction. Read more about how FFUs help you comply with ISO and other regulations.
