Constructed of polypropylene. The workstation is constructed of tough, chemically-resistant polypropylene. The three sides, top and base are thermally fused to provide a seamless shell. No glue to breakdown and no metal to rust. The blue work surface provides easy detection of spilled powders.

Air Flow Manager. For maximum containment, stable and uniform air flow is maintained by the air flow manager. The enclosure's face velocity is constantly monitored and displayed. Any change, often due to laboratory conditions or filter capacity, automatically initiates an adjustment to the blower speed keeping the air flow constant.

Alarms. A low airflow alarm visually and audibly alerts the user to insufficient airflow. The filter alarm monitors the filter life and alerts the user when the HEPA filter is saturated and needs to be changed.

Full protection during filter change. When changing the primary HEPA filter, the backup HEPA filter provides complete containment. Simply remove the pre-filter and primary HEPA filter from inside the enclosure. Then bag them and seal the bag, safely inside the workstation.

Ergonomically designed. Denver's Powder Safety Workstations feature an ergonomic, energy efficient design with angled face for worker comfort. The clear polycarbonate face can be opened completely to install equipment. The front sash can be raised to a height of 9", while maintaining full containment, allowing for greater accessibility to the workstation.

Aspen 200 Air Flow Diagram

1. Air from the room enters the Powder Safety Workstation and is drawn in a laminar flow toward the rear plenum of the enclosure.
2. This air is mixed with the contaminated air which contains powder which is not dense enough to fall to the work surface.
3. Next the air passes through the pre-filter. Here 95% of particles greater than 0.5 microns are trapped. Pre-filters extend the life of the more expensive HEPA filter by capturing large particles that take up precious space in the HEPA filter.
4. The air then enters the primary HEPA filter. Here 99.997% of all particles greater than 0.3 microns are captured. The air that leaves the primary HEPA is filtered and safe to return to the room.
5. The air then passes through the back-up HEPA filter. The back-up HEPA filter is only used during changing of the primary HEPA and comes with a 10-year warranty. Simply stated, if during normal use, the back-up HEPA filter ever needs changing we will send a certified fume hood expert to perform the task at no cost to the customer.
6. Clean, room-temperature air is returned to the room. Compared to traditional fume hoods, energy costs are saved. Instead of taking room air and venting it to the outside, the air is filtered and circulated back into the room.
