Terra Universal's USP 797-compliant Compounding Cleanroom uses modular construction to provide a turnkey ISO-rated Buffer Room/Ante-Room combination at an economical price point.  

  • All standard room configurations meet and often exceed the ISO 7 and ISO 8 ratings required by USP 797
  • Adding a single FFU upgrades the ISO classification to at least ISO 6 and smaller rooms can achieve ISO 5 air quality
  • Double-wall, insulated 304 stainless steel panels with radius corners provide smooth, ISO 5-compatible interior surfaces that stand up to daily cleaning and sterilizing procedure
  • Optional Environmental Control Systems can automatically record differential pressure data for auditing purposes
  • Internal partition with two-way swing door creates a separate ISO 8 ante-room for gowning and hand washing
  • Roomside replaceable fan/filter unit modules can be removed from ceiling grid without breaching the aseptic room seal and forcing a shut-down
  • Snap-in-place wall panels create a rigid, durable structure that requires no external bracing or ceiling support
  • Recommended Additional Equipment: USP 797-Compliant Sink, Tier II Environmental Control System, and Wall-Mounted Garb Dispensers

These turnkey sterile compounding cleanrooms include: (3) roomside replaceable fan/filter units, (2) fluorescent lights, (2) Magnehelic®gauges, (1) air speed gauge, (1) external swing door, (1) internal swing door, (1) tempered-glass viewing window, and (1) 115V/60Hz duplex outlet.

Hidden Costs of FRP Cleanrooms

Why use stainless steel panels when neither FDA nor USP call for them? The answer is simple: everything else costs more in the long run. We know because we tried.

Although FRP (fiberglass-reinforced) panels may seem an attractive approach to an FDA- or USP-compliant cleanroom, hidden installation and maintenance costs pose significant challenges. FRP panel application, a multi-step process requiring an extended installation schedule, involves specialized adhesive, fast-drying and unforgiving seam sealants, and – most critically – installers with the tools and know-how to apply them uniformly and consistently. Mistakes are costly because re-do is nearly impossible and can require cleanroom shut-down and re-certification. Although Terra installers can avoid these problems, projects outside Southern California require travel and living expenses that can extend for weeks. Working with contractors local to you is a hit-or-miss proposition since most lack experience with cleanroom

FRP projects performed to FDA guidelines. To make matters worse, finished FRP rooms cannot be easily modified, expanded, or repaired if damaged by repeated cleaning and sterilizing.

By contrast, Terra modular BioSafe® stainless steel cleanrooms offer both lower cost of ownership and a showcase facility that simplifies certification to FDA and USP regulations. These pre-engineered, quick-connect panels require no installation expertise; rooms typically go up in a day and offer smooth, easy-clean, durable surfaces. Ease of assembly also means ease of relocation; these cleanrooms can be disassembled and reinstalled quickly and inexpensively. Best of all, as a major steel purchaser and fabricator, Terra can offer its BioSafe stainless steel cleanrooms at the same price previously charged for FRP structures.

Given the hidden costs and installation risks of alternative designs, does anything but a BioSafe stainless steel cleanroom make sense?

Ask the USP Expert

Chris Munoz
Compounding pharmacists face a challenging regulatory environment that is rapidly evolving as state standards move into compliance with FDA and USP mandates. It's important to work with an equipment supplier that understands the complexities of licensing and accreditation procedures.

Schedule a one-hour consultation with Chris Munoz, PharmD to help clarify how the regulations impact your facility and what equipment you are required to use for your compounding activities.

Dr. Munoz teaches pharmacy compounding at the University of Southern California (USC) School of Pharmacy, and serves on the California Pharmacists Association's Policy Committee and Board of Directors. Following Chris's earlier work in compounding pharmacies and for pharmaceutical companies, he began a consulting firm specializing in the business of, and regulatory affairs for, pharmacy compounding.

Chris is an active member of the International Academy of Compounding Pharmacists. He earned his Doctor of Pharmacy degree at the University of Southern California, and his Masters of Business Administration at Chapman University's George L. Argyros School of Business and Economics.

503A Traditional Compounding Pharmacies and 503B Outsourcing Facilities:

How to Optimize Your Compounding Cleanroom for FDA Inspections

As a result of the 2013 Drug Quality and Security Act (DQSA), all traditional compounding pharmacies and outsourcing facilities are subject to FDA oversight. Since enactment, the FDA has taken aggressive steps to strengthen enforcement and implement stricter standards for sterile compounding. Any “insanitary conditions” are in direct violation of Sections 501(a)(1) and (a)(2)(A) of the FD&C Act (Title 21 CFR), which gives the FDA inspectors broad secretion for determining what constitutes sterile conditions.

Because adverse events and sterility test failures are a surefire way to attract the undivided attention of the FDA and State Board of Pharmacy, experts in the field of pharmaceutical compounding strongly recommend using an ISO 5 cleanroom to substantially lower the bioburden of the cleanroom environment and restrict the number of colony-forming units (CFUs) introduced into the critical areas.

Specify the following for compliance with cGMP requirements:

  • 1 additional FFU in the Buffer Room
  • 1 additional FFU in the Ante-Room
  • Tier II Environmental Control System

Please contact us to add these options to your compounding cleanroom.

Door and Window Options

Automated Sliding Doors
A no-touch motion sensor opens sliding door for passage into or out of the clean room. Get single or double doors to transport personnel and carts with hands-free operation. Sliding doors conserve forward space and close automatically to preserve pressure and cleanliness within the controlled environment. Urethane wheels stay locked in upper and lower tracks to ensure smooth sliding, and a microprocessor monitors door position to adjust speed of movement and braking. Visit Automatic Sliding Door Systems for more details and ordering information.

Automated Swing Door Opener
For hands-free door opening when side-to-side space may be an issue, opt for Terra’s Automated Swing Door Opener. The space-saving unit fits above the swing door; trigger the door motion with the swipe of a hand in front of the sensor pad. Operation is quiet and open/close speed is programmable. An on-board power supply eliminates the need for secondary power. This opener can be installed on single or double doors, and is ADA-compliant. Visit Automatic Swing Door Opener for more details and ordering information.


Tempered Glass Window
The 0.5" double-paned tempered glass window is secured between two 304 stainless steel retaining frames; the internal frame has no fasteners or other cleaning obstructions. Standard size: 47"W x 36"H (nominal); specify other desired size.
