Power Distribution Module Diagram
- PDMs house electrical components in an easy-access housing that makes it easy to add fan/filter units or lights if requirements change
- Control Panel with Operation Status Indicators provides convenient access to all controls and a visual confirmation of cleanroom operation
- Plug-and-play, modular design speeds up installation, whether of Terra-furnished modular cleanroom or Terra cleanroom components used in your own cleanroom structure
Terra’s Power Distribution Modules (PDMs) dramatically simplify connection of fan/filter modules (FFUs) and ceiling lights, while providing low-voltage power for one or more Control Panels
Each PDM accommodates up to 5 lights and 5 FFUs and must be wired to a dedicated 35A fused 120V circuit or a 30A fused 240V circuit. Select among four PDM types (see configuration chart below):
UL-Listed for Highest Safety and Quality
Ensuring the safety of your employees, customers, and products is essential. Terra's UL-listed PDM's and air filtering systems are manufactured to the highest standards to reduce the risk of damage, injuries, and electrical hazards such as electric shock and fires. UL (Underwriters Laboratories) is recognized around the world as the leader in product safety testing and certification. The UL listing helps meet municipal and other permitting requirements that may be required before a cleanroom can be approved for operation. It ensures safety and integrity of high voltage cleanroom electrical system, as evaluated by independent third-party UL.
Leave Room for Growth!
If there’s chance that you may require additional FFUs to accommodate cleaner conditions, leave each PDM below its maximum FFU capacity. FFUs and lights can be added at any time, with no need for an electrician or hard-wiring, as long as the maximum of five of either module per PDM is not exceeded.
Control Panel
- Provides centralized control and monitoring of cleanroom functions
- Typically mounted at the main entry of the cleanroom
- Optional Night Service Mode switches FFUs into low-energy mode during off-hours to lower operating costs without shutting down the cleanroom.
- Can be upgraded to Smart Control System for added environmental sensors and FFU control to meet critical performance/monitoring requirements.
Filter replacement alarm
- Helps avoid unexpected and costly cleanroom operational interruptions by automatically alerting for cleanroom filter replacements
- 1 Filter Replacement Alarm can cover for all Filter Fan Units (FFUs) in the cleanroom
- Provides both audible and visual alarm
- Audible: Buzzer with silencer
- Visual: TUI Logo flashes
- Includes adjustable alarm set-point to adjust frequency of filter replacement based on backpressure within a FFU
- Typically mounts next to the cleanroom control panel
- Connections:
- Power: power connects to either the cleanroom’s power distribution module, or to a standard 120V/220V outlet
- Pressure: ¼” plastic tubing connects from the alarm unit to one FFU
Night Service Switch
- Energy-saving mode saves 25% of fan operating costs by reducing power consumption during off-hours
- Maintains round-the-clock cleanroom integrity at lower cost
- Easy to activate via panel-mounted switch (Wireless Cleanroom Control System also available)
Why Pay More for Less?
Terra cleanrooms are designed to meet a specified ISO cleanliness rating when a cleanroom is in use: with operations in progress, process machinery humming, and personnel in motion. So why pay to maintain that level of FFU performance when a production shift ends and people, the greatest source of contamination, leave the room?
With a greatly reduced contaminant load, a cleanroom at rest maintains its target ISO cleanliness standard with much less airflow, fewer air changes—and decreased power consumption. Terra’s Night Service Switch provides this cleanliness at a nominal cost, giving you immediate cost savings.
Simply select the “Night Service” Switch when you turn off the lights and go home. A separate operation circuit drops all Fan/Filter Units (FFUs) into low-energy operation mode, shaving 25% of energy costs off your power bill while maintaining uninterrupted cleanroom performance at your specified cleanliness level. With Terra's Night Service Switch, operators can save up to 7,000 kilowatt-hours per year with a return on investment in slightly over a year.*
Ordering Information
A complete system includes fan/filter units and Terra's standard Power Distribution Modules (order separately), in addition to the units specified below. The Night Service Switch includes electronic configuration of each FFU controlled by this system. The Control Panel includes switch settings and indicator lights for Normal Mode and Night Service Mode, as well as a tamper-resistant master FFU Off switch.

Tips for Passing ISO, cGMP, FDA and Other Certifications
Know your ISO requirement
A Terra product specialist can offer general design advice or make a consultation referral. Regulated industries such as pharmaceutical compounding maintain clear requirements for ISO cleanliness and related cleanroom characteristics. Other operations may require a certification consultant to specify these design requirements based on specific operations being performed. Either way, make sure you know the applicable performance requirements before you select a room design or cleanliness level.
FFU Ceiling Coverage and Air Change Rate
ISO specifies permissible particle counts for each cleanliness level but not how many fan/filter units are required to meet these target values. Other organizations, including the Institute for Environmental Science, provide recommended ranges for FFU ceiling coverage.
Terra recommends the high value within each range, which in most cases accommodates typical contamination loads presented by personnel and equipment. Modular Power Distribution Modules make it easy to add as requirements change – plug-and-play connections eliminate the need for hard-wiring by an electrician.
Cleanroom Design and Materials
A Terra Product Specialist will advise on the proper panel and other component materials to meet specific requirements for ISO compatibility, sterilization, chemical resistance, static safety, and other environmental concerns.Environmental Control and Documentation
Adjustable exhaust vents and manual FFU speed controls on all Terra cleanrooms allow regulation of air change rates. For centralized display and control, select low-cost automated FFU speed controls, which also allow remote Building Management System (BMS) fan control and even dynamic fan adjustment in response to programmed pressure levels. Air pressure, temperature, and humidity data are logged for a traceable operating history. Modular cleanrooms are available with stand-alone air conditioning modules or can be integrated with existing A/C systems. Humidification and De-humidification systems meet specific RH requirements.
Cleanroom Wall Partitions
Modular cleanroom wall partitions serve as vertical dividers to separate existing internal spaces into class 100,000 to class 10 cleanroom environments. Wall partitions feature 2"-square all-steel frames to support pass through chambers, doors, and wall panels.
Modular Cleanroom Ceiling Grid

Converting an Office or Lab into a ISO 5, ISO 6, ISO 7 or ISO 8 Cleanroom
Facility managers who need classified cleanroom space generally face a difficult choice.
New construction requires a suitable site and can take months, even years, to complete. Depending on area requirements, installing a modular cleanroom inside an existing room is a faster, more economical alternative, but this room-within-a-room approach often creates unusable or inaccessible space.
Terra’s BioSafe Cleanroom Conversion System offers a more economical, space-efficient approach: converting an existing unclassified room into a cleanroom, using modular components to meet a wide range of environmental and access requirements.
Modular Ceiling Grid
This modular structure mounts directly to existing walls to form a drop ceiling, or rests on top of walls that have no ceiling. Its all-steel, interlocking design requires no external bracing (either column support or suspension cables) for spans up to 20 ft. (6096 mm). Larger spans entail a single internal support column or external ceiling support cable.
The grid's 2-foot x 4-foot (610 x 1220 mm) ceiling bays support cleanroom ceiling components: room-side replaceable HEPA fan/filter units (FFUs), LED or fluorescent lights, and polypropylene ceiling panels.
Terra’s WhisperFlow™ Room-Side Replaceable FFUs provide the vertical flow of micro-filtered air that removes contaminants inside the room. By selecting the proper quantity of FFUs, you can meet any cleanliness classification to ISO 5 (Class 100). Their design allows filter replacement from inside the cleanroom, without breaching the cleanroom ceiling. Lights and blank ceiling panels complete the ceiling structure. See additional information below.
BioSafe® Cleanroom Wall Systems
Our Class A fiberglass-reinforced plastic (FRP) panel system is the only one that is certified for use in ISO 5 cleanrooms. Applied with a non-outgassing polymer adhesive to nearly any wall surface, including gypsum wallboard, this material features a patented finish that creates a durable, noncontaminating surface that is highly resistant to chemicals and microbial growth. More economical Class C panel are available (see ordering information).
CPVC (chlorinated polyvinyl chloride) Class A wall panels also meet ISO 5 requirements. A solvent-free, non-outgassing adhesive adheres them to walls. Seams are welded to close all gaps and make this system a great choice for converting current building space into a cleanroom. CPVC resists damage from a broad range of chemicals, making clean-up faster and easier.
The links below provide more information on these and other components that comprise this system, including cleanroom doors, pass-through chambers, and flooring. Installation of smooth Class A BioSafe panels, with proper wall and ceiling coving, meets stringent ISO 5-6 and cGMP requirements for the most critical applications, including sterile processing. For less critical cleanroom requirements, consider FRP Class C panels.
