Dozens of customers for
Terra modular cleanrooms
  • Complete turnkey clean room meets cleanliness standards for control of submicron particles, ensuring a clean compounding environment
  • Internal partition with swing door creates a separate gowning ante-room, in accordance with USP 797 regulations
  • Powder-coated steel support frame creates a rigid, durable structure that requires no external bracing or ceiling support
  • BioSafe® interior Fiberglass-Reinforced Plastic (FRP) or C-PVC panels resist damage from physical contact, and stand up to IPA and other sterilizing agents
  • Includes two differential pressure gauges to simplify USP 797 certification

Terra's Compounding Clean Rooms provide the ideal environment for compounding sterile injectables and other critical operations.

Designed to meet or exceed the ISO 7 requirements of USP 797, the turnkey rooms include three HEPA filter/fan units that provide a total of 1950 CFM (3315 m³/hr) of 99.99% particle-free air (measured at 0.3 µm diameter). Class C FRP panels meet ISO 7 (Class 10,000) standards, while Class A panels perform to ISO 5 (Class 100) cleanliness requirements, and are Factory Mutual (FM) approved. C-PVC panels meet ISO 5 requirements and are FM approved.

Select between 6'W x 8'L and 6'W x 10'L floor plans, or specify a custom dimension. Both rooms include an internal partition with a swing door that creates a separate antechamber for personnel gowning or product staging. Both the entry and partition doors open inward, allowing workers to avoid potential contamination by backing-in, never having to touch the handles. In the typical configuration, the primary compounding room accommodates a 6'-long workbench, which provides ample space for a laminar flow hood, as stipulated by USP 797 requirements (order bench and hood separately).

FRP Panel Options

Both Classes of FRP panels feature a unique advanced polymer non-outgassing adhesive, allowing installation on surfaces such as drywall. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. Finally, a patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

Class A BioSafe interior panels are the only FRP wall panels certified to ISO 5 standards for added cleanliness, and FM approved for increased safety and fire hazard protection.

C-PVC Panel Option

Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels also offer excellent chemical resistance and prevent particle emission and microbial growth.

Their unique solvent-free silicone adhesive allows installation on wallboard substrate mounted to Terra's steel frame structure, creating a strong, rigid structure. Seams are welded to provide trim-free seams, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning (see photo above). More information on C-PVC panels...

Dual Magnehelic® pressure gauges, located on the outer control panel, monitor the cascading pressure levels in the anteroom and main room, simplifying USP 797 certification.

Call your Terra Product Specialist to discuss installation options, whether work is performed by Terra or an independent contractor. The USP 797 Compounding Clean Rooms below do not include floors; they are designed for installation on a flat, sealed, non-particulating, crevice-free surface, which can be caulked to the clean room frame to form a seal. Coved vinyl flooring can be added as an optional feature. Terra does not provide a finish for the exterior wallboard. When installation is completed, however, this surface can be finished and painted easily and inexpensively to match your facility.

Select 7-ft. or 8-ft. ceiling height (filter face to floor).
