ISO Class7 (Class 10,000) up to 350° C.
The Lytzen class 10,000 depyrogenation oven is without internal filters. Only filters on the air inlet and exhaust are necessary. The chamber construction and the sealing of the chamber guarantee, that class 10,000 is obtained without use of internal HEPA-filters throughout the complete cycle. As it can be seen from the adjacent particle report, Lytzen is actually far below the class 10,000 limit. The absence of internal filters reduces the overall price for the depyrogenation oven considerably.
