Hood Materials Ordering Guide

How to Order:

Optional panel kits are available for models with interchangeable side panels. Application specific materials help support required conditions inside your laminar flow hood.

    Standard Panel Configurations:
    • [-SS] 304 Stainless Steel (with transparent SD-PVC sash)
      • Solid stainless steel walls simplify cleaning by minimizing cracks and crevices where particles or germs can accumulate.
      • Superior durability resists corrosion from a wide range of chemicals/solvents
      • Preferred material wherever frequent cleaning and sterilization are required
      • Not compatible with interchangeable panel kits
    • [-SD] Static-Dissipative PVC (SD-PVC)
      • Transparent with blue-gray tint
      • Safely conducts surface charges to ground, protects against particle aggregation
      • Broad resistance to wide range of cleaning agents such as isopropyl alcohol for easy sterilization
    Additional high performance panel kits available:
    • [-PC] Polycarbonate
      • Transparent with slight gray tint
      • Cracks less easily with approx. 250x impact resistance of glass and 15x impact resistance of acrylic
      • Increased thermal resistance (115–130 °C (239–266 °F)) helps withstand repeated steam sterilization
      • Broad resistance to wide range of cleaning agents such as isopropyl alcohol for easy sterilization
    • [-BA] Black Acrylic (with transparent SD-PVC sash)
      • Opaque black panels block ambient light for photo-sensitive applications or improved privacy
      • Economical, and provides high tensile strength
      • Damaged by frequent contact with alcohol and other common cleaning agents
    • [-TG] Tempered Glass
      • Combines visual clarity with broad chemical resistance
    • [-AA] Amber Acrylic
      • Orange tint filters out UV and blue light to protect light sensitive materials from degrading, or changing composition
      • Economical and provides high tensile strength
      • Damaged by frequent contact with alcohol and other common cleaning agents
    • [-WA] White Acrylic (with transparent SD-PVC sash)
      • Translucent, diffuses ambient light and provides some privacy
      • Economical and provides high tensile strength
      • Damaged by frequent contact with alcohol and other common cleaning agents
    • [-FP] FM4910 Polypropylene (with transparent SD-PVC sash)
      • Opaque white panels block light for light-sensitive applications or improved privacy
      • FM 4910 compliant, flame retardant
      • Excellent chemical resistance
    • [-FV] FM4910 CPVC
      • Transparent with slight blue tint
      • FM 4910 compliant, flame retardant
      • Controls static electricity, prevents charge generation on the surface thereby controlling particle attraction
      • Excellent chemical resistance, surface hardness, and mar resistance

Recirculating Design Minimizes Turbulence

Recirculating 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 durable and long-lasting LED lighting to illuminate the work area. The LED strip is positioned behind the front shield to prevent direct exposure to the operator's eyes.

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. Easily configure with power cord passthroughs and choose application specific panel materials to support required conditions inside the hood.

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.
