Product Details
  • Available Certified ISO Grade Designs: ISO 6, ISO 7, ISO 8
  • Portable base stand safely mounts cleanroom FFU’s above floor for horizontal laminar airflow
  • Horizontal flow FFU stand is ideal when ceiling space is unavailable or overhead system unsuitable
  • Versatile horizontal FFU system can be customized for compatibility with most Terra FFU’s
  • Includes adjustable leveling feet for optimal stability, optional casters for increased mobility
  • The FFU base stand can serve as a horizontal flow wall module, compatible with many cleanroom or laboratory applications that require positive laminar airflow. It can also be configured for negative pressure exhaust applications such as isolation rooms.
  • Economical alternative to a laminar flow hood, suitable for mitigating airborne contamination in semi-sterile operations such as food processing.
  • For positive pressure: Choose an FFU with standard airflow direction. Simply position the module to supply clean horizontal laminar airflow into a room, or enclosure. It can also be positioned next to sensitive equipment or materials that are mounted close to the floor.
  • For negative pressure (exhaust): Choose a reverse flow FFU design. Flexible ducting can be connected to the exhaust flange of the reverse flow FFU to direct exhaust through a window or wall.
  • Custom stands can be built for specific applications - call or chat with a product specialist for details.
  • All materials are non-shedding and cleanroom-compatible.

• Certified ISO Grade Design: ISO 6

• Unit of Measure: of 1
