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

Horizontal Laminar Flow Station Airflow Diagram

Multi-speed filter/blower modules provide a continuous wash of HEPA-filtered air for process protection. Internal baffling plates and diffuser panel ensures uniform air speed across work area; make-up air return slots minimize edge turbulence and extend filter life.

Air Return Ducts

For enhanced air-stream control, the flow station features return ducts along the edges of the hood opening. These ducts reduce backwash caused by placing objects near the work surface edge, a common source of turbulence inside a clean bench.

Simple User Interface

Operator controls include the ON/OFF switches, blower speed controls, and a Minihelic™ backpressure gauge for monitoring the load on the HEPA filter. When the backpressure roughly doubles from the initial readings, the filter needs replacing.

Duplex Outlet

A GFCI power receptacle is installed on the right-hand side of the hood interior for operational convenience. Alternative mounting locations can be specified at time of order.

Status Indicator Light

The Terra Universal logo incorporates an LED light that functions as a status indicator. The TUI logo will flash when the unit is connected to power, but the blower is switched off. A solid glow indicates the station is fully operational.

HEPA Filter Access Panels

For horizontal laminar flow hoods, the rear vent panel can be easily removed to access the HEPA filters.

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.

Durable Powder Coating Finish

Terra’s durable powder coating formulation exceeds the ASTM and ISO paint standards for hardness, thickness, humidity resistance, gloss and impact testing.

  • 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).
