Compressed Air/Vacuum Maintenance

House Air/Vacuum Performance Work Statement USMA Bartlett Hall Science Center has compressed air and vacuum distributed throughout building. These services emanate from two central facilities. One is in the subbasement; the other is on the roof. Preventive maintenance is required on both systems. The equipment in the subbasement consists of: ? Quadraplex Hitachi model 110U-8.5CG2H air compressors with Weg 15HP motors and two dual-tower dryers (Trident Dryspell with DS 31-200 controllers). ? Triplex Busch model RC0400.B033.1037 vacuum pumps with Baldor 15HP motors. ? Both have control systems integrated by Amico Air and Vacuum Systems. The equipment on the roof consists of: ? Triplex Powerex OBS150700E air compressors with Baldor motors and a single dual tower dryer. ? Duplex Busch model RC0400.B033.1035 vacuum pumps with Baldor 15HP motors. ? Both have control systems integrated by Engineered Medical Systems and Equipment. The preventive maintenance being sought will be performed quarterly and annually.
