Whisperflow™ Benchtop Laminar Flow Hoods

• Portable, economical system converts any benchtop surface into a laminar flow station (standard widths to 72", with 24" or 30" depth)
• Provides air flow speed >90 feet/minutes (measured with HEPA filter)
• Quiet operation: 50 dBA measured 30" from filter face
• Select vertical or horizontal flow configuration to meet your requirements
• Available with a variety of hood materials, including static-dissipative PVC
• Work surfaces available to meet any cleanliness requirement

This versatile laminar flow hood gives you a particle-free work environment on any available work surface.

FFU: Quiet, Reliable Operation
It consists of two modules: a filter/fan unit (FFU), which houses a particle filter, and a hood. The FFU houses a HEPA filter, rated 99.99% efficient with 0.3 micron particles. Its internal baffle system ensures uniform face velocity. The low vibration level ensures minimal disruption of high-precision assembly or test procedures performed inside the hood. ULPA FFUs, rated 99.99% efficient @ 0.12µm particles, along with ionization units are also available.

Hood Provides a Versatile Enclosure Configured to Your Requirements
Terra manufactures hoods out of several materials to meet a broad range of chemical and cleanliness requirements.

Lightweight acrylic affords full visibility of work in progress. Static-Dissipative PVC eliminates static charges and the particles they attract, making it ideal for the most critical contamination requirements. Powder-coated or 304 stainless steel provides outstanding durability and resistance to most cleaning solvents. All hood materials are housed in a powder-coated steelor stainless steel frame for strength and easy cleaning. All hoods include a hinged front access shield that restricts the air exit and enhances laminar flow.

Hoods
Hoods Stainless steel frame provides durable support for hood material indicated below. Each model includes a fluorescent light and a hinged access shield that increases air speed by restricting the air exhaust. See chart below for nominal hood widths and depths. Vertical flow models are 30.25"H; horizontal flow models are 24"H.
