• Provides air flow speed >90 feet/minutes (.46 m/s) measured with HEPA filter
• Quiet operation: 50 dBA measured 30" (762 mm) 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

Horizontal Flow Model

Vertical Flow Model 1688-30C-SS, 60"W x 24"D (1524 mm x 610 mm)

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
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 (768 mm); horizontal flow models are 24"H (610 mm).

Cleanroom IonBar™

Vapor-Sealed Fluorescent Illuminator
Standard hoods above include a fluorescent light fixture. This upgrade fixture is enclosed in a vapor-sealed static-dissipative PVC housing. Price includes installation. Select length that fits inside your enclosure. Operates on 120 or 220VAC (50/60Hz).

Vibration-Isolated Stand
Two-piece design isolates WhisperFlow Hood from sealed laminate top work surface to isolate fan vibration. Adjustable models (shown in photo) allow height adjustment in 1" increments. 30"D and other materials available at TerraUniversal.com.
