Features and Benefits

BioSafe® WhisperFlow Hoods: One-Piece Design With Seamless Tracks

BioSafe® Whisper Flow Hoods feature a one-piece design free of cracks or crevices that harbor microbes and contaminants. Surface are easy to wipe down, resistant to alcohol-based cleaners and harsh biocides.

HEPA-Filtered Reverse Flow Fan Unit

High Efficiency Particulate Air (HEPA) Filter Fan Unit provides clean micro-filtered air, shown in reverse-flow hood that captures contaminants generated in the work area for safe cleanroom release.

Recessed LED Lighting Illuminates Work Area

Laminar flow hoods include long-lasting LED lighting to illuminate the work area. The LED strip is flush-mounted for easy disinfection.

Versatile Removable Panels

Removable side-panels increase the versatility of your hood by improving visibility plus simplifying equipment access. The side-panels are lined with foam gasket and slide into the hood’s frame for a simple yet effective seal. Each panel is easily removed to simplify cleaning and disinfection.

Tilt-Up Sash

Tilt-up sash enhances laminar airflow and prevents air from blowing directly at the operator’s face. Static-dissipative PVC material resists chemicals and eliminates particle attraction from static charges.

Integrated Status Indicator Light

Operation status indicator (OSI) light glows continuously when hood is plugged in and turned on to confirm filtration unit is operational. The OSI blinks when the unit is plugged in but switched off.

BioSafe®: Terra's Ultimate Cleanliness Rating

Terra's BioSafe products are designed for the most critical applications: no gaps and crevices where microbes colonize, rounded corners for easy disinfection, won't produce contaminants during sterilization, and exceeds cGMP, IEST, ASTM and ISO 14644-1 requirements.
