H-Y Tumble Drum Details
VAI’s Environmental Control Monitoring Division (ECMD) has addressed the needs of cleanroom laundries, and the pharmaceutical, biotechnology, semiconductor, and electronics industries with the Helmke-Yeich (H-Y) Tumble Drum.
The purpose of the H-Y Tumble Drum® is to test garments, wipers, gloves, and other cleanroom ready products to determine the amount of particulates and shedding. The H-Y Tumble Drum provides effective measurement of quality levels to ensure facilities are meeting the required standards.
In the Institute of Environmental Sciences and Technology document, “Garment System Considerations for Cleanrooms and Other Controlled Environments IEST-RP-CC003.2” the H-Y Tumble Drum is recommended for testing garments, wipers, gloves, and other cleanroom ready products.
The H-Y Tumble Drum tumbles items in a rotating drum to release particles from the surface of the item. It is designed to be connected to an automatic particle counter in order to sample the air within the drum to determine the average particle concentration of the air. Results depict the level of contamination the product will emit to the cleanroom environment per minute.
