Horizontal Flow Cleanroom

Features Key
  Standard
  Option

A Status Indicator Lights: Glow to indicate FFUs are operational; flash when FFUs are off
B HEPA or ULPA fan/filter units provide a uniform flow of particle-free air
C Fluorescent or LED light modules (LED strips available for mounting directly to steel grid)
D Control panel includes internal room pressure gauge and other selected instruments (not shown)
E Several door designs: aluminum swing or sliding, vinyl strip shields (not shown)
F Select acrylic, static-dissipative, glass or polycarbonate wall panels
G Steel frame supports weight: no bracing required
  Options include Night Service setting, pass-through chambers, A/C, vacuum, DI water and gas utilities
Laminar-Flow Cleanroom

Flexible vinyl strip-shield entrance removed to show interior of this custom
12-foot-high polypropylene cleanroom. Options installed: three 2'x4' HEPA fan/filter units and two LED light modules.


  • Horizontal laminar-flow (HLF) cleanrooms meet any ISO or size requirement
  • Critical processes placed in direct line of laminar flow for maximum cleanliness
  • Side-mounted blower modules are ideal for facilities with reduced overhead clearance
  • White powder-coated steel frame supports walls, fan/filter units and ceiling grid modules

Terra's unique Horizontal Laminar-Flow Cleanroom is designed as an alternative to traditional vertical-flow, positive-pressure cleanrooms; some processes or samples are best handled when placed closer to the source of filtered laminar airflow, as well as upstream from personnel. The turbulent effect of air striking the work surface is reduced in a HLF environment.

In buildings with ceiling-height restrictions, top-mounted fan/filter units may not be possible due to clearance requirements. Terra's lower-profile HLF cleanroom solves this problem. The powder-coated steel frame supports wall panels, ceiling , control panel, lights and fan modules.

Available wall panels:
Acrylic is strong and affordable. It is the clearest of the cleanroom-compatible plastic materials
Polycarbonate also strong, resists many common acids, including those used for cleaning
White Polypropylenestands up to acids while shielding processes from view
Tempered safety glass is transparent, non-porous and the best choice for aseptic applications
SD PVC prevents electro-static discharge or the attraction of contaminating particles

Choose a swing or sliding door, or a flexible strip shield entrance (with strip shields, no wall vents are necessary for air release).

WhisperFlow™ FFUs make laminar airflow uniform across the entire filter face; dead zones cause turbulent eddies that compromise cleanliness. Internal baffles and blower speed control ensure balance and homogeneity. In a Horizontal Laminar Flow cleanroom, the FFU proximity makes filter replacement easier and faster; no need for ladders or standing platforms.

WhisperFlow Fan/Filter Units

Cleanroom Light Modules

Typical HLF Cleanroom internal height is 7' (8' external), but the room will be designed to your specifications. The fan/filter units need a 24-inch clearance from walls or other furnishings: 13" for FFU housing, with an additional 11" for proper air flow.

Strip Shield Door

Strip Shield Door
Strip shields can be mounted in place of a standard door or 4-foot (1219 mm) hardwall panel at any location along the perimeter of the cleanroom. Click Here for ordering information.

Control Panel with Operation Status System

Control Panel
Status Light
Mounted to the right of the access door, this panel allows convenient control of filter/fan units, lights, ionizing modules, and other environmental monitoring equipment selected for your hardwall modular cleanroom. Fabricated of mirror-finish 304/316L stainless steel or powder-coated steel to match cleanroom design. This system includes top corner operation status indication (OSI) lights that display cleanroom status: lights glow when FFUs (fan/filter units) are in operation, and flash intermittently to indicate they are off. For Hardwall and BioSafe® Cleanroom designs only, it includes a Magnehelic® Differential Pressure Gauge (0.25-0-0.25"WC).
