The purpose of this project is to develop a personal air-sampling pump with the following specifications:
1. The pump will draw 10 liters of air per minute against a pressure drop of 12 inches of water, operating continuously for 24 hours from a rechargeable battery pack.
2. The design will be optimized for quiet operation and low power, with a low noise level.
3. The pump will contain sophisticated control and data logging capabilities.
4. This device will be lightweight, user-friendly, and compatible with Dr. Sioutas’ sampler.
This project was initiated by the Center in October 2000, under a previous grant (Grant No. R824834C007), and it will be continued under this follow-on grant. The project was developed in response to NUATRC RFP 2000-01 "Development of a High Efficiency Pump for the Personal Particulate Matter Monitor." Within 60 days of signing the contract, SKC provided an appropriate quality assurance and quality control (QA/QC) plan that is in compliance with the NUATRC and EPA QA/QC procedures.
Significant progress has been made with the development of the pump. The initial design phase has been completed. The pumping mechanism has been designed, and the machined prototype has been produced. The prototye was refined to achieve required flow range, and the power consumption and noise were reduced to minimum levels. The flow control sensor and electronics were designed, as well as the microprocessor-based control system.
Production of the first sampler prototype has been completed. The case and battery pack were designed. The first prototype sampler was built from machined parts. Microprocessor software was developed to allow performance testing.
A working unit/sample pump was demonstrated at the October 2001 NUATRC Scientific Advisory Panel-Investigators' Meeting in Chapel Hill, NC.
· Case design and mold tools are not yet completed. The initial design drawings were sent to the mold tool suppliers for evaluation and price quote. The feedback from the mold tool suppliers suggested parts of the design that could be improved. SKC has heeded these improvements and is working closely with the mold tool vendors. Consequently, a delay in the production of the molded cases will occur. They are expected to be delivered to SKC, Inc., in early January 2002.
· SKC has decided to develop all its future pumps based on the electronics developed for the Leland Legacy pump. SKC expects to launch the pump at the Association for Industrial Hygiene Meeting to be held in June 2002, in San Diego, CA.
