/ L\I * K. Geisen September 13# 1965 W. K. Biotler Polymerizer Evacuation System, Buildings 111 and 121 he polymerize? evacuation system in Buildings 111 and 121 were Installed in 19t2. An Inveetl^aticn was made cn the evacuation uyetemo in these buildings end the results arc as follows* BT7ItI>IH3 111 W3ST SIDS fcucti work partially plugged and motor on the blower was turning in the wrong direction. The duct work was cleaned and the motor leads reversed. llxo blower is now moving approximately 120 CPS at the polymerioer manhole with throe hose bfeations In use. Thi3 is slightly under one air change per minute per polymeriser. HJXLDXHS 111 EAST SIDE /.ucKomcter readings indicate that the duct work to polymorizers It. 15.

It is suggested that these ducts be cleaned in the came manner as the ducts on the west side of the building. amoBffl 121 west sion Anemometer readings indicate that the dxict work to polymer!zero 33# 33 36, 41, 42, 43, and 44 is partially plugged. The main duct is badly dented and tbex*e are several leaks in the branch lines due to the rusting. Also, it appears that there is water trapped in some of the branch linea. It is suggested that the duct work be cleans! whore possible end be replaced at the rusted out and badly dented places. 1't might be advisable to install ft larger horsepower meter and increcsp the blower speed In order to obtain more CFH for evacuation of the larger polymerizers. - *v BFG63441 2 SUjX?I:T3 121 2AS? 5I5S Anemometer readings indicate that the duct work is badly plumed. Alec, there are fc'-ro large holes In the main duct end several rusted crab spst3 in the branch lines. It la susseated that the duct work be cleaned where possible and replaced at the badly deteriorated sections. It might be advisable to install a larger horsepower motor and increase the blower speed in order to obtain more CFH for evacuation of the larger polymerlocra* Presently all four evacuation systems are equipped with an American Blower #3, Type T Mover to deliver 625 CFll-ii ! S.P.; those blowers are- driven by a one horsepower, 1725 RPM motor. *. /sjr* h,cc-i H* H. Striby - ", Woods, Jr* ?* CA.. CWoagllnyer A. >/, Clements File W.K. Uistler ZOdSCT2 ' 13 BFG63442
