Product Details
• Terra's Horizontal Laminar Flow Hood exceeds ISO 5 particle requirements for critical operations in the biotech, pharmaceuticals, electronics and semiconductor industries
• Powerful, low-energy fan/filter modules provide a back-to-front laminar flow of HEPA-filtered air across the work surface
• The variable-speed, electrically commutated filter/fan(s) provide average air speeds of 109 FPM (0.55 m/s) while maintaining an industry-best noise level of 50 dBA and energy efficiency
• Internal baffling plates and anodized aluminum diffuser panel ensure uniform air speed across the work area
• All models include a powder-coated steel stand with adjustable leveling feet that raise the work surface to 31” (787 mm) above the floor
• Take-up ducts along the edges minimize turbulence in the work area, providing a smooth exit for airflow
• Built-in recessed illuminator provides diffused lighting without interfering with laminar flow
• Interior surfaces, including the side panels and work surface, are 304-stainless steel; as an option, components can be electropolished to remove subsurface contaminants for an ultra-clean finish
• Exterior surfaces feature a chip-resistant, powder-coated finish

UV Germicidal Lamp
The V-Ray germicidal UV lamp is installed within a Terra hood to inhibit microbial growth on the work surface -
Static-Neutralizing Ionizing Bar
Airflow from the blower distributes positive and negative ions onto the surfaces below, neutralizing static charges that can lead to electro-static discharge and attract particles. -
Utility Valves
Ball valves (petcocks) are available for utilities such as nitrogen, compressed air, vacuum, DI water, or other process gases. Valves are composed of chrome-plated steel or ABS plastic. -
Explosion-Proof Power Switches
UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points. -
Replacement HEPA or ULPA Filters
Choice of HEPA (rated 99.99% efficient @ 0.3 µm particles) or ULPA (rated 99.999% efficient @ 0.12 µm particles) -
Work Station Drawers
Available in ABS plastic or stainless steel, these cleanroom-compatible drawers come in a number of sizes and drawer configurations (6” top drawer/12” bottom drawer shown).
