Features and Benefits

Recirculating Design Minimizes Turbulence

Recirculating ISO 5 vertical laminar flow hood exceeds Class 100 cleanroom conditions to protect your work area from particle contamination. The adjustable rear vents pull air back through the fan/filter unit mounted on top. Bench top hoods can also mount on top of base cabinets (sold separately) for easily accessible storage space underneath your workstation.

Adjustable Top Vent and Removable Rear Plenum

Recirculating laminar flow hoods feature an adjustable top vent to control the amount of recirculated air. The rear plenum is removable for cleaning and maintenance.

Adjustable Rear Plenum for Precise Airflow Control

Recirculating clean bench designs feature an adjustable rear plenum to minimize turbulence in the work area and extend the life of the HEPA filter.

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

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.

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.
