Terra's Powder Containment Room combines many benefits of a modular cleanroom, including a filtration system that maintains cleanliness levels to Class 100 (ISO 5).

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.*

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 capture 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 (0.5 m/s), in accordance with cleanroom standards.

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

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

Ceiling fan/filter 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.

* The CleanZone Ventilation System is designed to draw environmental nuisances away from personnel inside the Powder Containment Room. It is NOT designed to protect personnel against biohazards. Regulated hazardous materials should not be used inside this system.

Fig. A. Neutral Pressure Room: Protects Outside Lab
CleanZone Recirculation system creates a HEPA-filtered clean zone that captures hazardous powders, protecting the external environment against nuisance powders.
Positive Pressure Room   Negative Pressure Room
Fig. B. Positive Pressure Room: Protects Product
Addition of ceiling HEPA filter/fan units creates a positive pressure of filtered air, providing enhanced protection of product against airborne nuisances.
Fig. C. Negative Pressure Room: Protects Personnel
Optional Air Handling Module expels air to create a negative pressure that draws air away from personnel. Can be operated with or without ceiling filter/fan units.

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" (838 mm) above floor. Specify multiple zones for larger rooms.

A four-foot (1219 mm) opening on the shorter wall accommodates one of Terra’s standard door options. Standard height is 7' (2134 mm) from filter face to floor (8'3", 2530 mm, overall, including filter/fan units), allowing placement beneath standard 9' (2743 mm) ceilings. Indicate other desired heights.
