Inquiry (采购产品): air shower prefilter Good morning, We boutght an air shower about 2 years ago and we would like to know when we are supposed to change the HEPA filter and also we would like to change the prefilter but we don't have any information about this product such as catalog number, price, etc. So can you give me these informations so I will be able to place an order quickly. N.B. Our air shower looks like the AS-200E model. The prefilter is 2 pieces taped together (why???) with dimensions 12x18x1 each and have been supplied by Dayton. Thank you very much! cm **** Hidden Message ***** cynthia moore 2950 chemin polytechnique Montreal, QC H3T 1J4 CAN Company: IRIC, Montreal University Title: animal facility supervisor Phone: 514-343-6111, ext 0516 Fax: 514-343-2379 E-mail: cynthia.moore@umontreal.ca **** Hidden Message ***** cynthia.moore@umontreal.ca
