Valulie Dust-Free Hood two-operator
Model shown: 1715-06B
These economical hoods provide a dust-free enclosure for a host of contamination-sensitive operations, including pharmaceutical packaging and weighing, microelectronics assembly and testing, and chemical processing.

To configure a system, select the desired hood size and material below, and then add Filter/Fan Unit(s). Optional accessories include vibration-isolated stands, flange adapters (for use with in-house clean air or ventilation systems), and several lights.

Each hood comes with a swing-up access shield of a compatible material, indicated on the ordering table. Access shields can be selected in other materials or with custom cut-outs; let us know your requirements.

Narrow Fan/Filter Unit
Includes a 99.99% efficient HEPA filter and a low-noise, low-vibration 3-speed motorized impeller to provide a continuous wash of particle-free air. The narrower, 16"-deep FFU allows Terra to make space-saving enclosures with smaller footprints. An Operation Status Indicator flashes when the unit is turned off, providing a convenient visual monitor of hood operation. Select one FFU for single hoods, and two for twin models. One Power Distribution Module per hood is required (see below).

Power Distribution Module
Simplifies operation by providing a single power connection for FFUs, lights, ionizers, and other electrical components. Includes relays and circuit breakers for overload protection. Operates on standard 15A circuits. One required per ValuLine Dust-Free Hood (price includes system integration of selected options).

Stands
Hoods Vibration-isolated stand with free-standing hood frame   Laminar Flow Hoods Non-isolated (one-piece) stand
Vibration-isolated work-surface stand with free-standing hood frame isolates vibrations caused by the hood blower   Non-isolated (one-piece) stand
The bottomless design of the ValuLine Dust-Free Hood allows it to be placed on either one-piece stand or two-piece stand/frame. A two-piece stand/frame isolates the work surface from the hood itself to minimize transmission of blower vibration—perfect for use with high-precision scales or microscopes.

Both designs feature raised lips to hold the hood securely in place. All frames (whether isolated or not) are made of rigid square tubing with a white powder-coat finish, and include stainless steel scuff sleeves to prevent scuffing along the bottom leg support. The work surface stands 32" above the floor. Be sure to select the size (large or small, single or twin) to match your hood.
