Terra's Powder Containment Room combines many benefits of a modular cleanroom and biological safety cabinet, including a filtration system that maintains cleanliness levels to Class 10 (ISO 3).

Unlike conventional cleanrooms, it features a versatile air handling system that lets you configure the working space for your requirements.

Neutral Pressure Room: 100% Air Recirculation (Fig. A Below)

Configured as a neutral pressure room, this system ensures 100% recirculation of exhausted air and complete protection of the external environment.

An outlet filter/blower module recessed in the wall at the rear of the processing area draws air away from the operator into dual HEPA outlet filters, which contain any airborne chemical powder. These filters can be discarded or processed for chemical reclamation.

Outlet air then passes through a make-up air duct and back into the ceiling filter/fan unit mounted on the ceiling. Filtered air flows downward from above the work area at a speed of about 90 feet/minute, in accordance with cleanroom standards.

Positive Pressure Room: Filter/Fan Units (Fig. B Below)

This additional protection optimizes product purity by controlling airborne aerosols, microbes, and other submicron particles.

Ceiling filter/fan units (FFUs) create a positive pressure inside the room that blocks the inrush of contaminants. FFUs can be positioned at the access area to form a contamination barrier, or uniformly throughout the ceiling grid to create laminar airflow.

Negative Pressure Room: Exhaust Ventilation (Fig. C Below)

For additional protection of personnel inside the room, the CleanZone Recirculation System lets you adjust the percentage of air recirculated into the containment room.

By exhausting a portion of the air drawn into the filtration system, you create a negative pressure that pulls air away from the operator. A flanged adapter panel, either with or without adjustable damper, lets you duct exhausted air to an in-house ventilation system. Terra's Air Handling Modules include a high-volume fan and filter for ductless ventilation.

Ordering Information
Use the catalog numbers at right to indicate the cleanroom material for your application. Each system includes a BioSafe™ all-steel room manufactured to the floor plan you specify, including ceiling grid. Select one or more CleanZone Recirculation Systems (see specifications). Unless otherwise specified, this system is mounted at the center wall opposite the access opening, with filters mounted 33" above floor. Specify multiple zones for larger rooms.

A four-foot opening on the shorter wall accommodates one of Terra’s standard door options. Standard height is 7' from filter face to floor (8'3" overall, including filter/fan units), allowing placement beneath standard 9' ceilings. Indicate other desired heights.
